Key Highlights:

• The FDA issued warning letters to five sunscreen manufacturers regarding mousse and foam formulations, citing their unapproved status under current OTC monograph regulations.
• These dosage forms are not recognized as Generally Recognized as Safe and Effective (GRASE) and require an approved application or final FDA order for lawful marketing in the U.S.
• Beyond regulatory compliance, concerns were raised about product packaging resembling food items, potentially increasing the risk of accidental ingestion, especially by children.

Introduction:

The summer sun, while a source of warmth and vitality, also necessitates diligent protection against harmful ultraviolet (UV) radiation. Sunscreens, in their myriad forms, serve as a primary defense. Over the years, consumer preferences and technological advancements have spurred innovation in sunscreen formulations, moving beyond traditional lotions and creams to encompass gels, sticks, sprays, and even foams and mousses. These newer formats often aim to enhance user experience, encouraging more consistent application and adherence. However, the path of innovation frequently intersects with the rigid framework of regulatory oversight, particularly in highly controlled markets like the United States.

Recently, the U.S. Food and Drug Administration (FDA) signaled a significant regulatory intervention, sending warning letters to several prominent sunscreen brands, including Supergoop!, Vacation Inc., Kalani Sunwear, Fallien Cosmeceuticals, and K & Care Organics (BOTAÓ). The crux of the FDA's concern centers on a specific class of products: mousse and foam sunscreens. These letters, dated August 6, 2025, and made public on August 12, explicitly state that these particular dosage forms cannot be legally sold in the U.S. without an approved application or a final FDA order. This directive sends a clear message to the industry, highlighting a critical regulatory gap and underscoring the complexities of bringing novel cosmetic-drug hybrid products to market under existing frameworks.

The FDA's action is not a sudden or arbitrary decision but rather an enforcement of long-standing regulations governing over-the-counter (OTC) drugs, under which sunscreens are classified. This move brings into sharp focus the distinction between consumer appeal and regulatory compliance, particularly as brands strive to innovate in a competitive landscape while navigating a stringent and often slow-to-adapt regulatory environment. Understanding the implications of these warning letters requires delving into the specific regulatory basis for the FDA’s actions, examining the cited violations, and considering the broader industry perspectives on innovation, safety, and consumer use.

The Regulatory Bedrock: Why Sunscreens Are Drugs and Not Just Cosmetics

In the United States, sunscreens are not merely beauty products; they are categorized as over-the-counter (OTC) drugs due to their intended use of preventing sun damage and reducing the risk of skin cancer. This classification places them under the strict purview of the Federal Food, Drug, and Cosmetic (FD&C) Act. The regulatory framework for OTC drugs is primarily governed by the OTC Monograph system, a public standard for certain nonprescription drug categories. This system specifies active ingredients, labeling, and dosage forms that are Generally Recognized as Safe and Effective (GRASE) for particular uses.

The FDA's warning letters precisely hinge on this GRASE determination, or rather, the lack thereof for certain dosage forms. According to section 505G(m)(2) of the FD&C Act, products that fall outside the established GRASE conditions must either receive an approved New Drug Application (NDA) or be authorized through a final FDA order before they can be legally marketed. For sunscreens, the current OTC sunscreen monograph specifies a limited list of GRASE dosage forms: oil, lotion, cream, gel, butter, paste, ointment, stick, spray, and powder. Noticeably absent from this list are mousse and foam formulations.

The FDA explicitly stated in its letters that “No final order has been issued by the Secretary under 505G(b) or 505G(c) that would authorize marketing of sunscreen in a foam (aka mousse) dosage form.” This indicates a clear regulatory void for these innovative delivery systems. Manufacturers wishing to market sunscreens in mousse or foam formats would, therefore, need to undertake the rigorous process of submitting an NDA, a pathway typically reserved for novel drugs that involves extensive clinical trials and data submission to demonstrate safety and efficacy. Alternatively, they would need to successfully petition the FDA for a final order that specifically includes these dosage forms within the GRASE classification for sunscreens, a process that can be lengthy and challenging.

This regulatory distinction is not trivial. It means that even if a mousse or foam sunscreen contains active ingredients that are themselves GRASE (like zinc oxide or avobenzone), its innovative delivery format renders the entire product unapproved for marketing under the current monograph. The FDA's stance reflects a cautious approach to drug regulation, where the delivery mechanism itself can impact the product's stability, efficacy, and safety profile. For example, the physical characteristics of a foam or mousse, such as its density, spreadability, and film-forming properties, could influence how effectively the active ingredients are distributed on the skin and how long they remain protective. Without specific data and a formal review process for these dosage forms, the FDA maintains that their marketing is non-compliant.

The enforcement action signals the FDA's commitment to upholding the integrity of the OTC monograph system. It underscores that while the cosmetic industry thrives on innovation and appealing product textures, these advancements must align with established regulatory pathways, particularly when the products are classified as drugs designed to protect public health. The letters serve as a reminder that market-driven innovation, no matter how popular with consumers, cannot bypass the stringent scientific and regulatory scrutiny required for drug products.

Detailed Citations: Specific Brands Under Scrutiny

The FDA's August 6, 2025, warning letters targeted five distinct companies, each cited for marketing mousse or foam sunscreen products without the requisite regulatory authorization. These examples highlight the specific violations identified by the agency and underscore the broad application of its regulatory stance on unapproved dosage forms.

Supergoop!

Supergoop! received a warning letter for its Body Mousse SPF 40. The FDA's communication explicitly stated that this product's foam dosage form is not covered by the final administrative order M020, which pertains to OTC sunscreens. The letter detailed, "To date, no final order has been issued by the Secretary under 505G(b) or 505G(c) that would authorize marketing of a sunscreen in foam (aka, mousse or whip) dosage form...[and] there is no FDA-approved application in effect for your drug product." This citation directly points to the fundamental issue: a widely available and popular product utilizing an unapproved delivery format. Supergoop!'s response indicated a commitment to working with the FDA to resolve the matter, emphasizing that the issue pertains to labeling and not the product's safety or efficacy. This perspective reflects the common industry challenge of navigating regulatory nuances for innovative formulations.

Vacation Inc.

Vacation Inc. found its Whipped Sunscreen SPF 30 under similar scrutiny. This product had garnered attention for its unique formulation, developed in collaboration with Clayton Corporation, known for its technology used in whipped cream products. The FDA's letter to Vacation Inc. stated that the product was "misbranded under section 502(ee) of the FD&C Act because it is a foam dosage form that has not been authorized under a final order or approved application."

Beyond the unapproved dosage form, Vacation Inc. faced an additional, particularly interesting violation related to its packaging. The FDA noted, "Your ‘Classic Whip Sunscreens’ are misbranded under Section 502(i)(1) of the FD&C Act, 21 U.S.C. 352(i)(1), which provides that a drug is misbranded if ‘its container is so made, formed, or filled as to be misleading,’ because they are packaged in containers that resemble food canisters customarily purchased by U.S. consumers.” This specific concern highlights a crucial public safety dimension: the risk of accidental ingestion, especially by children, who might mistake the product for food given its resemblance to whipped cream canisters. This dual citation underscores the FDA's comprehensive approach to consumer protection, encompassing not just the product's inherent properties but also its presentation and potential for misuse.

Kalani Sunwear

Kalani Sunwear's Hawaii Whip SPF 50 was also cited for lacking the required marketing authorization. The FDA's letter confirmed, "no FDA-approved applications pursuant to section 505 of the FD&C Act are in effect for your drug product." This aligns with the broader theme of the warning letters: unapproved dosage forms requiring explicit FDA authorization. Kalani Sunwear’s CEO, Anna Xavier, affirmed that the company immediately removed the product from its U.S. website to ensure compliance. She also provided important context, stating that their Sun Mousse SPF 50 is developed and manufactured in Sweden, adhering to stricter EU safety and efficacy standards, including advanced UV filters not yet approved in the U.S. This points to a disparity in regulatory environments, where products perfectly compliant and safe in one major market face hurdles in another.

Fallien Cosmeceuticals

Fallien Cosmeceuticals received a warning for its Solar Protective Mousse SPF 50+. The FDA's message reiterated the core regulatory principle: "Sunscreens in dosage forms other than oil, lotion, cream, gel, butter, paste, ointment, stick, spray, and powder require an approved application or final order prior to marketing." This serves as a clear articulation of the monograph's limitations and the consequent non-compliance of mousse formulations.

K & Care Organics (BOTAÓ)

The FDA's letter to K & Care Organics (BOTAÓ) was comprehensive, addressing multiple foam and mousse products under their brand, including “BOTAÓ Kids Mineral Foam Spray,” “BOTAÓ Baby Mineral Foam Spray,” and “SUN & SHINE Sunscreen Mousse.” The agency stated that these products were "misbranded under section 502(ee) of the FD&C Act" due to being unapproved delivery formats marketed without proper FDA application submission. The inclusion of "Kids" and "Baby" products in this list likely amplifies the FDA's concern, given the heightened vulnerability of these consumer groups to potential product-related issues.

Collectively, these warning letters serve as a robust enforcement action, demonstrating the FDA's firm stance against the marketing of unapproved drug products, regardless of their popularity or perceived efficacy. The consistent message across all letters reinforces the regulatory requirement for specific authorization for novel dosage forms in the sunscreen category.

Industry Voices: Balancing Innovation with Compliance

The FDA's warning letters have ignited discussions within the beauty and pharmaceutical industries, prompting experts to weigh in on the implications for product innovation, consumer experience, and regulatory adherence. The consensus among industry professionals is a recognition of the FDA's authority, coupled with a nuanced understanding of the challenges and opportunities presented by such regulatory actions.

Carl D’Ruiz, Head of NA Beauty & Care Science Advocacy and Business Development at dsm-firmenich, highlighted the inherent tension between innovation and existing regulatory frameworks. He acknowledged that while some mousse formulations might indeed meet safety and efficacy standards, the fundamental issue lies in the dosage form's unapproved status. D'Ruiz framed the situation as "an opportunity to revisit and expand the scope of approved dosage forms, aligning innovation with modern formats that enhance consumer experience and compliance." His perspective champions the idea that consumer-friendly formats, like mousses, can actually promote public health by encouraging more consistent and thorough sunscreen application. If sunscreens are enjoyable and easy to use, consumers are more likely to apply them regularly, thereby reducing the incidence of sunburn and long-term skin damage. This viewpoint suggests that the regulatory landscape should evolve to accommodate beneficial innovations that align with public health goals.

Formulation challenges are another critical aspect, as pointed out by cosmetic chemist Kelly Dobos, MS, MBA. She emphasized that creating mousse sunscreens is not straightforward, requiring "precise control over rheology and stability" to ensure that active ingredients, such as zinc oxide or avobenzone, are uniformly distributed throughout the product. Uneven distribution could compromise the sunscreen's protective capabilities, leading to inadequate UV protection in certain areas of application. Dobos underscored the paramount importance of compliance, stating unequivocally, "whether we agree with them or not, the rules are the rules. Running afoul of the rules can have serious consequences like product recalls or seizures." This highlights the practical and financial ramifications for companies that fail to meet regulatory standards, irrespective of their product's perceived quality or market success.

Dermatologist Jane Yoo, M.D., reinforced the FDA's position regarding GRASE dosage forms. She reiterated that "Only sunscreens in the form of oil, lotion, cream, gel, butter, paste, ointment, stick, spray and powder may be lawfully marketed… No final order has been issued by the FDA that would authorize marketing of a sunscreen in a foam (mousse/whip)." Dr. Yoo also brought attention to a critical consumer safety concern identified by the FDA: the packaging of certain mousse sunscreens resembling food items. She explained, "The FDA wants to minimize the risk of accidental ingestions, especially by children." This concern is not theoretical; instances of accidental ingestion of non-food products by children are a persistent public health issue. Packaging that mimics edible products, particularly those like whipped cream, can dangerously mislead young children, potentially leading to emergency room visits. This multi-faceted safety consideration—from formulation integrity to packaging design—illustrates the broad scope of the FDA’s oversight.

The collective sentiment from these industry experts suggests a complex landscape where innovation must be carefully balanced with regulatory diligence. While the desire to create appealing and effective sunscreens is strong, manufacturers must navigate the existing legal framework. This may involve either investing in the lengthy and costly process of securing an NDA or advocating for changes to the OTC monograph system to include new, safe, and effective dosage forms. The current situation serves as a stark reminder that even well-intentioned product developments can face significant market hurdles if they do not align with established regulatory pathways.

Company Responses and Path Forward

Following the issuance of the warning letters, the FDA mandated a response from each company within 15 working days, outlining their corrective actions. Failure to comply could escalate to severe consequences, including product seizure or injunctions, emphasizing the seriousness of the regulatory breach.

CosmeticsDesign US reached out to all implicated brands for their official statements, providing insight into their immediate reactions and planned responses.

Supergoop! issued a statement acknowledging the FDA's communication regarding their PLAY SPF 50 Body Mousse. A spokesperson clarified, "At Supergoop! we remain committed to innovation in sun care and the highest standards of product efficacy and safety, [and] the recent communication from the FDA regarding our PLAY SPF 50 Body Mousse is focused on product labeling and has nothing to do with its safety, effectiveness, or formula." This response highlights Supergoop!'s assertion that the issue is procedural and related to marketing authorization rather than inherent safety or performance flaws. The spokesperson added, "We are working closely with the FDA to resolve this matter as we continue to uphold the high standards our consumers expect from us." This indicates a willingness to engage constructively with the regulatory body to find a resolution, which likely involves either ceasing marketing the product in its current form in the U.S. or pursuing the lengthy process of an NDA.

Kalani Sunwear provided a more detailed response through its CEO and Partner, Anna Xavier. She confirmed that "the recent FDA warning letter relates solely to the fact that, under U.S. regulations, SPF products are classified as drugs and therefore require prior registration before being offered for sale in the United States." Similar to Supergoop!, Kalani Sunwear emphasized that the letter "does not state that mousse-format sunscreens are inherently less effective, nor does it raise any concerns regarding the safety, quality, or performance of our formulation." Crucially, Xavier stated, "following receipt of the letter, we immediately removed the product from our U.S. website to ensure full regulatory compliance." This swift action demonstrates an immediate commitment to rectifying the non-compliance.

Xavier further elaborated on the product's background, noting that their Sun Mousse SPF 50 is "developed and manufactured in Sweden by one of Europe’s most respected sunscreen producers and meets or exceeds the strict safety and efficacy standards in place within the European Union." She also pointed out a significant regulatory disparity: "EU regulations require a significantly higher level of proven UVA protection compared to the U.S., and our formulation utilizes the most advanced UV filters currently available — filters which are not yet approved for use in the U.S., where the last new UV filter approval occurred in 1999." This statement underscores a broader industry frustration regarding the slow pace of new UV filter approval in the U.S., which often lags behind other major markets like the EU. Kalani Sunwear’s confidence in their product’s quality, safety, and effectiveness, despite its unapproved status in the U.S., reflects the differing regulatory philosophies and scientific advancements across global markets.

As of the publication of the original report, CosmeticsDesign US had not received responses from Vacation Inc., Fallien Cosmeceuticals, or K & Care Organics (BOTAÓ). The absence of a public response does not necessarily indicate inaction but might suggest that these companies are internally assessing their strategies, which could include similar paths of product withdrawal or engagement with the FDA.

The immediate removal of products from U.S. markets by some companies demonstrates a clear understanding of the regulatory risks involved. The long-term implications for these brands and the wider industry are significant. Companies may need to reformulate products into GRASE dosage forms, pursue costly and time-consuming NDA processes for their mousse/foam variants, or discontinue these specific product lines for the U.S. market entirely. This situation also reignites calls from the industry for the FDA to modernize the OTC sunscreen monograph to include newer, consumer-preferred dosage forms and to accelerate the approval of advanced UV filters that are widely used and deemed safe in other developed countries. The industry's ability to innovate responsibly hinges on a dynamic regulatory environment that can adapt to scientific advancements and evolving consumer needs without compromising safety.

Global Regulatory Disparities and Innovation Bottlenecks

The FDA's recent crackdown on mousse and foam sunscreens in the U.S. highlights a persistent and growing challenge for global beauty and personal care companies: navigating widely divergent regulatory landscapes. The contrasting situation with the European Union (EU) offers a poignant example of these disparities, particularly concerning sunscreen formulations and approved UV filters.

In the U.S., sunscreens are classified as over-the-counter (OTC) drugs and are regulated under the FDA's stringent monograph system. This system, while ensuring a high standard of safety and efficacy for approved products, is notoriously slow to adapt to new technologies and ingredients. As Kalani Sunwear's CEO, Anna Xavier, pointed out, the U.S. has not approved a new UV filter since 1999. This means that many advanced, broad-spectrum filters widely utilized and considered safe and effective in Europe and other parts of the world are not available for use in U.S. sunscreens. These newer filters often provide superior protection against UVA rays, offer better cosmetic elegance (e.g., less white cast), and can be incorporated into lighter, more aesthetically pleasing formulations, including mousses and foams.

The EU, conversely, regulates sunscreens as cosmetics, albeit with strict safety requirements. This regulatory approach allows for a more agile adoption of new UV filters, provided they pass rigorous safety assessments. The result is a market where consumers have access to a broader range of innovative sunscreen products featuring cutting-edge ingredients and diverse textures. For example, European sunscreens commonly feature filters like Tinosorb S, Tinosorb M, Mexoryl SX, and Uvinul A Plus, which offer enhanced UVA protection and often allow for more elegant, less greasy formulations compared to the more limited palette of filters available in the U.S.

This fundamental difference in regulatory classification—drugs in the U.S. versus cosmetics in the EU—leads to significant market fragmentation. A product like Kalani Sunwear’s Sun Mousse SPF 50, which is developed and manufactured to meet or exceed strict EU safety and efficacy standards and utilizes advanced UV filters, is deemed non-compliant in the U.S. simply because its dosage form is not listed as GRASE under the outdated monograph. This situation creates an "innovation bottleneck" in the U.S. sunscreen market. Manufacturers are hesitant to invest heavily in developing novel formulations with unapproved filters or dosage forms when the pathway to market approval is so uncertain, costly, and prolonged.

The consequences of this bottleneck are manifold. U.S. consumers are potentially deprived of access to sunscreens that offer superior protection, improved cosmetic elegance, and diverse textures that might encourage better compliance. While traditional formulations are effective, some consumers prefer lighter, non-greasy, or novel formats like mousses, which can lead to more consistent use. Furthermore, U.S. manufacturers face a competitive disadvantage globally, as they are restricted from incorporating the latest advancements in UV filter technology into their products for their domestic market. This can stifle domestic research and development in sunscreen innovation.

Industry advocates have long called for a modernization of the FDA's OTC sunscreen monograph, advocating for a more streamlined process to evaluate and approve new UV filters and dosage forms. They argue that aligning U.S. regulations more closely with international standards, particularly those in the EU, would benefit public health by providing consumers with a wider array of effective and user-friendly sunscreen options. The FDA's recent warning letters, while enforcing existing law, inadvertently highlight the urgent need for such regulatory reform to prevent the U.S. market from falling further behind in the global sun protection landscape. The current scenario forces brands to make difficult choices: either withdraw innovative products from the U.S. market, invest heavily in an NDA process for each new dosage form, or continue to operate within the confines of an increasingly anachronistic regulatory framework.

The Broader Impact on Consumer Choice and Public Health

The FDA's enforcement action on mousse and foam sunscreens, while rooted in regulatory compliance, carries significant implications for consumer choice and, ultimately, public health. The availability of diverse and appealing sunscreen formats plays a crucial role in encouraging consistent and adequate sun protection.

From a consumer perspective, the recent popularity of mousse and foam sunscreens can be attributed to their unique sensory profiles. Unlike traditional creams or lotions, these formats often boast a lightweight, airy texture that spreads easily, absorbs quickly, and leaves little to no residue. This enhanced cosmetic elegance can significantly improve the user experience, particularly for individuals who find traditional sunscreens heavy, greasy, or difficult to apply evenly. For parents, a fun, foamy texture might also make the often-dreaded task of applying sunscreen to children more manageable and even enjoyable. When a product is pleasant to use, consumers are more likely to apply it correctly and regularly, which is paramount for effective sun protection.

The withdrawal or unavailability of these preferred formats could lead to decreased compliance with sun protection guidelines. If consumers find their preferred products no longer on the market, they might revert to less appealing options, leading to less frequent or less thorough application. This presents a public health concern, as inadequate sunscreen use directly contributes to higher risks of sunburn, premature skin aging, and, critically, skin cancers like melanoma.

The FDA's primary concern regarding the unapproved status of these dosage forms stems from a protective stance: ensuring that any product classified as a drug is demonstrably safe and effective in its marketed form. While manufacturers and industry experts argue that the active ingredients are already GRASE and that the foam/mousse format simply enhances delivery, the FDA requires specific data and a formal process to confirm that the change in dosage form does not compromise stability, efficacy, or safety. For instance, the physical properties of a foam might affect how well the UV filters maintain their integrity over time or how uniformly they spread across the skin, potentially creating areas of insufficient protection.

Moreover, the FDA's concern about misleading packaging, particularly exemplified by Vacation Inc.'s product resembling a whipped cream canister, directly addresses a serious safety issue. Children, in particular, are prone to accidental ingestion of household products. When sunscreens are packaged to mimic food items, the risk of such incidents increases. While parents are expected to supervise, attractive and deceptive packaging can easily lead to mistakes, potentially requiring emergency medical intervention. This specific misbranding citation underscores the FDA's holistic approach to product safety, extending beyond chemical composition to include presentation and potential for misuse.

The current situation therefore creates a dilemma: how to balance consumer preference for innovative and user-friendly formats with rigorous regulatory oversight. While the FDA’s actions are designed to ensure public safety and regulatory integrity, they also highlight the need for the regulatory system to evolve at a pace that keeps up with product innovation. A modernized monograph that could incorporate new dosage forms and more advanced UV filters, perhaps through an expedited review process, could serve both public health goals and industry innovation. Without such adaptation, the U.S. market may continue to lag behind, potentially limiting consumer access to optimal sun protection strategies and impacting overall public health outcomes related to UV exposure.

Future Outlook and Policy Advocacy

The FDA's recent actions against mousse and foam sunscreens serve as a potent catalyst for continued dialogue and potential policy changes within the U.S. regulatory landscape for sunscreens. The industry response, characterized by both compliance and advocacy, suggests a sustained effort to modernize the existing framework.

One likely immediate outcome is the withdrawal of many existing mousse and foam sunscreen products from the U.S. market, as demonstrated by Kalani Sunwear’s prompt action. Companies that wish to reintroduce these formats will face the arduous and costly path of submitting a New Drug Application (NDA). The NDA process is typically reserved for novel drugs and requires extensive clinical trials, manufacturing controls, and data submission to prove safety and efficacy for a specific formulation and dosage form. This can take years and millions of dollars, a barrier that many smaller or mid-sized companies may find prohibitive.

Another potential avenue for manufacturers, particularly those with significant market presence, is to actively engage in policy advocacy. This involves petitioning the FDA to amend the OTC sunscreen monograph to include mousse and foam as recognized GRASE dosage forms. Such a process would necessitate the submission of scientific data demonstrating the safety, stability, and efficacy of these formats, often through industry consortiums or trade associations pooling resources. This approach, while still lengthy, could provide a broader industry-wide solution rather than product-specific NDAs. Advocacy groups and industry associations have long pushed for the modernization of the sunscreen monograph to allow for faster approval of new UV filters, and this latest regulatory action might add new impetus to include novel dosage forms in that conversation.

The global perspective, particularly the more progressive regulatory environment in the European Union, will continue to play a significant role in this advocacy. The argument that products are deemed safe and effective in other highly regulated markets strengthens the case for their approval in the U.S. It highlights the potential for U.S. consumers to miss out on superior or more cosmetically elegant sun protection options available elsewhere. This disparity often fuels consumer demand and, consequently, industry pressure for regulatory reform.

Beyond immediate compliance, companies will need to re-evaluate their product development strategies for the U.S. market. This might involve:

1. Focusing on GRASE dosage forms: Prioritizing innovation within the currently approved list of creams, lotions, gels, sticks, sprays, and powders.
2. Reformulating existing products: Adapting popular mousse or foam formulations into compliant formats, while attempting to retain as much of their desirable sensory properties as possible.
3. Investing in long-term regulatory pathways: For companies committed to specific innovative formats, beginning the NDA process or actively participating in monograph amendment efforts.
4. Enhanced consumer education: Regardless of product format, emphasizing the importance of consistent and correct application of sunscreen, especially in light of potential changes in product availability.

The FDA's actions, while disruptive in the short term, could ultimately lead to a more robust and responsive regulatory system for sunscreens in the U.S. It pushes the industry to either conform to existing regulations or to collaboratively champion the necessary reforms to ensure that innovation can flourish within a framework that continues to prioritize public health and safety. The outcome will depend heavily on the sustained engagement between industry, regulatory bodies, and consumer advocates, all striving to balance scientific progress with the imperative of protecting skin from the sun's harmful rays.

FAQ:

Q1: Why did the FDA issue warning letters to sunscreen manufacturers? A1: The FDA issued warning letters because certain sunscreen products, specifically those in mousse or foam dosage forms, are being marketed in the U.S. without the necessary regulatory authorization. Under the Federal Food, Drug, and Cosmetic (FD&C) Act, sunscreens are classified as Over-The-Counter (OTC) drugs. The current OTC sunscreen monograph recognizes only specific dosage forms as Generally Recognized as Safe and Effective (GRASE), such as oils, lotions, creams, gels, and sprays. Mousse and foam forms are not included in this list, meaning they require an approved New Drug Application (NDA) or a final FDA order before they can be legally sold. No such approval or order has been issued for these formats.

Q2: What is the specific issue with mousse and foam sunscreens? Are they unsafe or ineffective? A2: The FDA's concern is primarily regulatory, not necessarily about the inherent safety or efficacy of the products themselves. The letters indicate that these dosage forms are "unapproved" under the current monograph system. This means that while the active ingredients (e.g., zinc oxide, avobenzone) might be GRASE, the specific delivery method (mousse/foam) has not undergone the formal review and approval process required for drug products to ensure its stability, consistent delivery of active ingredients, and overall performance. Some letters also cited concerns about packaging that might mislead consumers, particularly children, into mistaking the sunscreen for a food product (e.g., whipped cream).

Q3: What are the specific companies that received warning letters? A3: The FDA sent warning letters to Supergoop!, Vacation Inc., Kalani Sunwear, Fallien Cosmeceuticals, and K & Care Organics (BOTAÓ).

Q4: What happens next for these companies and their products? A4: The companies were given 15 working days from receipt of the letters to respond to the FDA with corrective actions. This typically means either ceasing the marketing and sale of the non-compliant products in the U.S., or initiating the lengthy and costly process of submitting a New Drug Application (NDA) for their specific mousse/foam formulation, or working with industry groups to advocate for changes to the OTC monograph. Failure to comply could result in more severe enforcement actions, such as product seizures or injunctions. Some companies, like Kalani Sunwear, have already removed their products from the U.S. market.

Q5: Why are sunscreens regulated as drugs in the U.S. but often as cosmetics in other countries like the EU? A5: This difference stems from varying regulatory philosophies and historical contexts. In the U.S., sunscreens are classified as drugs because their primary intended use is to prevent disease (skin cancer) and mitigate the effects of harmful UV radiation, which are therapeutic claims. Therefore, they fall under the strict drug regulations of the FDA. In the European Union and many other regions, sunscreens are typically regulated as cosmetics but are subject to rigorous safety and efficacy testing, often including more modern UV filters not yet approved in the U.S. This distinction leads to significant disparities in approved ingredients, formulation flexibility, and market access for innovative products across different global markets.

Q6: Does this mean all foam or mousse products are now illegal in the U.S.? A6: Yes, for sunscreen products, any mousse or foam formulation is considered unapproved for marketing in the U.S. unless it has gone through an individual NDA process and received specific FDA approval. The FDA's action makes it clear that these dosage forms are not recognized under the current OTC sunscreen monograph. Consumers may still find such products on shelves temporarily as companies take action to comply, but their continued marketing without approval is in violation of federal law.

Q7: How can consumers ensure they are using an FDA-compliant sunscreen? A7: Consumers should look for sunscreens in dosage forms recognized as GRASE under the current monograph: oils, lotions, creams, gels, butter, paste, ointments, sticks, sprays, and powders. Always check the product labeling for an SPF value and broad-spectrum protection. If you have concerns about a specific product, you can check the FDA's website for warning letters or approved drug products.

Q8: What impact does this have on sunscreen innovation in the U.S.? A8: This action could slow down innovation in new sunscreen delivery formats in the U.S. as companies become more cautious about investing in formulations not explicitly listed as GRASE. It highlights the need for a modernization of the OTC sunscreen monograph to allow for a more streamlined process for evaluating and approving new dosage forms and more advanced UV filters, ensuring that U.S. consumers have access to the latest and most effective sun protection technologies available globally.
