Key Highlights:

Avant’s Ultimate Hydration Day & Night Duo pairs a featherlight hyaluronic-acid day cream with a richer night treatment for face and eyes; the set is currently discounted from £233 to £99.
Formulations combine humectants (hyaluronic acid), emollients (jojoba oil, shea butter) and barrier-supporting vitamin B3; reviewers report improved hydration, reduced morning puffiness and softer fine lines.
The set suits people prioritising hydration and glow, but sunscreen, proper layering and realistic expectations about “clinically proven” marketing claims remain essential.

Introduction

Hydration remains a cornerstone of visible skin health and of how skin ages. Products that restore and retain moisture often produce rapid, visible improvements that complement longer-term actives such as retinoids or peptides. Avant’s Ultimate Hydration Day & Night Duo brings hyaluronic acid to the centre of both morning and evening steps while extending the formulas to the eye area — a frequent locus of early fine lines and puffiness. The current promotion reduces the bundle from its regular list price to a fraction of that cost, prompting renewed interest from shoppers and skincare commentators.

This review unpacks the day and night formulas, situates the actives in scientific terms, examines user feedback, and offers practical guidance on how to fold the pair into an effective routine. It also compares the set to similar market options and highlights limitations that matter for shoppers seeking measurable anti-ageing outcomes.

What’s in the Avant Ultimate Hydration Duo?

Avant markets the duo as two award-winning formulas packaged with a signature vegan leather toiletry bag. The headline act in both products is hyaluronic acid, supported by complementary ingredients aimed at hydration, barrier repair and skin texture improvement.

Day cream (Pro-Intense Hyaluronic Acid Illuminating Day Cream): Described as featherlight, it contains hyaluronic acid plus sea water, jojoba oil and soy lecithin. The formula targets hydration, radiance and the visible appearance of fine lines while also helping to regulate oil and sebum production.
Night cream (Deluxe Hyaluronic Acid Vivifying Face and Eye Night Cream): Positioned as a richer, multi-purpose treatment for face and eyes, it blends hyaluronic acid with shea butter and vitamin B3 (niacinamide) to restore moisture, aid overnight regeneration and reduce signs of tiredness.

Both creams are promoted as suitable for the eye area, which simplifies a routine for users who prefer a two-product regimen rather than separate eye creams. Avant also asserts clinical data: that the duo delivers deep hydration, diminishes fine lines and improves skin elasticity, with 97% of trial participants reporting smoother-feeling skin.

How hyaluronic acid works: the science behind the claims

Hyaluronic acid (HA) has become a staple ingredient because of a simple, demonstrable effect: it binds and holds water. HA is a glycosaminoglycan naturally present in skin and connective tissues; topically applied, it acts as a humectant that attracts water to the stratum corneum, temporarily increasing hydration and producing a plumping effect.

Key mechanistic points:

Immediate visual impact: By increasing water content of the outer skin layers, HA reduces the appearance of fine lines and imparts a smoother surface. Results are typically visible quickly but are transient unless maintained with ongoing use and a robust skin barrier.
Molecular weight matters: Different molecular weights of HA penetrate to different depths. High-molecular-weight HA sits mainly on the skin surface for significant moisture retention, while low-molecular-weight fragments may reach deeper layers and support longer-term hydration. Many modern formulations blend multiple molecular weights to optimise both instant and sustained benefits.
Complementary ingredients: Hyaluronic acid performs best when the skin barrier is intact. Occlusives (like shea butter) reduce transepidermal water loss and lock moisture in, while emollients (jojoba oil) smooth the skin surface and mimic natural lipids, improving texture and comfort. Niacinamide strengthens the barrier and can reduce redness or uneven tone.

Those effects explain why a hyaluronic-centred day cream and a richer night cream can produce complementary outcomes: a lighter moisturiser for daytime comfort and sebum regulation, and a denser night product to support overnight repair and moisture retention.

Ingredient breakdown: what each component contributes

Understanding formulation strategies helps assess whether a product will perform as claimed. Avant’s duo combines classic moisturizing technology with targeted actives.

Hyaluronic acid: Hydration and plumping. Expect immediate temporary smoothing of fine lines and fuller-feeling skin when used consistently.
Sea water: Mineral-rich seawater is sometimes added for its mineral content and potential toning effects. It can provide trace elements like magnesium and zinc, though the cutaneous benefits are modest and largely supportive rather than transformative.
Jojoba oil: A lightweight emollient with a lipid profile similar to sebum. It helps condition the skin without feeling greasy and can assist in regulating oiliness for some users.
Soy lecithin: Functions as an emulsifier and can improve texture and penetration of some actives. It also contributes phospholipids that aid barrier function.
Shea butter (night cream): A rich occlusive and emollient that seals in moisture and softens skin; especially useful overnight when the skin’s repair processes are active.
Vitamin B3 (niacinamide): Multifunctional. Niacinamide reduces transepidermal water loss, helps regulate sebum, can improve skin tone, and is broadly tolerated across skin types.

Each component plays a role in the duo’s stated goals: immediate hydration, overnight moisture retention and texture improvement.

Day cream: texture, claims and suitability

The Pro-Intense Hyaluronic Acid Illuminating Day Cream is sold as a featherlight hydrator that boosts radiance and reduces the appearance of fine lines. Benefits to expect during regular daytime use:

Lightweight wear: The formula’s emphasis on featherlight texture suggests compatibility with makeup and sunscreen layering. Users with normal to combination skin should feel comfortable applying it under SPF without pilling.
Sebum regulation: Jojoba oil and soy lecithin may help balance oiliness, making it a reasonable option for those who are concerned about midday shine but still need hydration.
Radiance boost: Increased hydration tends to brighten the skin visually by smoothing micro-texture and diffusing light across the skin surface.

Practical notes:

Sunscreen remains non-negotiable. A hydrating day cream can improve how sunscreen sits on the skin, but UVA/UVB protection is the primary anti-ageing intervention.
For oily skin types, perform a short trial to ensure the day cream does not contribute to breakouts. While the formula claims sebum regulation, individual responses vary.

Night cream: repair, richness and eye-area claims

The Deluxe Hyaluronic Acid Vivifying Face and Eye Night Cream aims to do heavier lifting while you sleep. It contains hyaluronic acid for hydration, shea butter for occlusion and niacinamide for barrier repair and tone regulation.

What to expect:

Enhanced overnight moisture retention because of shea butter’s occlusive properties. This is useful for dry skin types or anyone experiencing seasonal tightness.
Reduced morning puffiness reported by several users, potentially reflecting both hydration and improved lymphatic drainage over time; topical treatments can help the appearance of puffiness but sleep patterns, salt intake and allergies also play significant roles.
Eye area suitability: Applying the same cream to face and eye zones simplifies routines, but some people prefer dedicated eye products with lighter textures or active ingredients formulated specifically for periorbital skin.

Practical points about night creams:

Richer textures can feel heavy for oily or acne-prone skin. Those skin types may prefer using the day cream at night or alternating with the night cream.
Night routines present an opportunity to layer actives such as retinoids. Because niacinamide and hyaluronic acid are well tolerated with retinols, the night cream should integrate without irritation for most users, although patch testing is prudent when combining products.

Real-user feedback: what shoppers report

Consumer reviews on Avant’s site and retailer pages give a qualitative perspective. Common themes emerge:

Hydration and plumping: Multiple reviewers describe immediate hydration and a plumper feel to the skin. These reports align with the expected effects of hyaluronic acid.
Reduced puffiness and softer fine lines: Several users report less puffiness around the eyes and a softening of fine lines with continued use. Such outcomes are typical when the eye area’s hydration improves; full wrinkle reversal is not implied.
Light texture and pleasant scent: Users often comment on the light, non-greasy feeling and a pleasant fragrance. Fragrance can be a pro in terms of experience but a potential con for fragrance-sensitive skin types.
Desire for larger sizes: One recurrent complaint concerns jar size. Enthusiastic users sometimes wish for larger formats, a common reaction when a product performs well.

These anecdotal data points are valuable for real-world expectations but do not replace controlled clinical measures. Consumer reports also highlight the importance of product feel. If a moisturiser feels luxurious and fits into daily rituals, consistent use increases the chance of sustained benefits.

Interpreting “clinically proven” and product claims

Manufacturers often cite clinical testing to support claims like “clinically proven to hydrate” or “97% felt smoother skin.” Understanding what those metrics mean helps set expectations.

Scope of trials: Cosmetic clinical trials vary widely in design, sample size and endpoints. They may be short-term (days to weeks) and focused on subjective measures (participant questionnaire) or objective ones (instrumental skin hydration readings).
Meaning of percentages: A statistic such as “97% saw smoother skin” is typically based on participant-reported outcomes in a specific study cohort. It signals high satisfaction among trial participants but does not automatically equate to the same result across all skin types or conditions.
Regulatory context: Cosmetic products are not evaluated for therapeutic claims the way drugs are. “Clinically proven” in cosmetics generally refers to efficacy in controlled cosmetic trials, not the same regulatory scrutiny applied to medicinal claims.

Buyers should value clinical claims but also read them against trial duration, sample diversity and whether outcomes were measured objectively or subjectively.

How to use the duo: step-by-step routines and layering advice

A simple morning and evening routine will maximise benefits while keeping irritation risk low.

Morning routine (suggested)

Cleanse: Use a gentle cleanser suited to your skin type.
Antioxidant serum (optional): A vitamin-C serum or antioxidant product can help counter oxidative stress and improve radiance.
Avant Day Cream: Apply a pea-sized amount across the face and the orbital bone if you choose to include the eye area.
Sunscreen: Apply a broad-spectrum SPF 30 or higher as the final daily step. Reapply throughout the day as needed.

Evening routine (suggested)

Remove makeup and cleanse thoroughly.
Targeted treatments (optional): If you use retinoids or topical peptides, apply them on clean, dry skin. If you are new to retinoids, introduce slowly and avoid daily application initially.
Avant Night Cream: Apply to face and eye area. If layering over retinol, consider applying the night cream after retinol is fully absorbed, or alternate nights to reduce sensitisation for new retinol users.
Occlusive (optional): For very dry skin, dab a thin layer of facial oil or a light occlusive over the night cream to seal in moisture.

General layering rules

Apply lighter, water-based products first, followed by heavier creams and occlusives.
Hyaluronic acid-based serums and creams can be used both morning and night. They increase hydration irrespective of the time of day.
Avoid mixing high-concentration actives with fragranced moisturisers if you have sensitive skin.

Combining with retinoids, AHAs and other actives

Many users will want to combine hydrating creams with anti-ageing actives. The duo’s formulations are generally compatible with common actives, but sensible precautions apply.

Retinoids: Niacinamide and hyaluronic acid pair well with retinol. Niacinamide can soothe and reduce irritation, while hyaluronic acid supports hydration that reduces retinol-related dryness. Start retinoids gradually and consider alternating nights if sensitivity develops.
AHAs/BHAs: Exfoliating acids can be used in the same routine but may increase sensitivity to sunlight. Use on alternate nights or earlier in the evening, and prioritise sunscreen the next day.
Vitamin C: A vitamin-C serum in the morning complements the day cream, contributing antioxidant protection and brightening.

Patch testing and gradual introduction are recommended whenever you add multiple actives to avoid irritation.

Who benefits most — skin types and concerns

The duo is designed with broad appeal, but outcomes vary by skin type and goals.

Dry to dehydrated skin: Most likely to see immediate, perceptible improvement. The night cream’s shea butter and hyaluronic acid will provide both occlusion and humectancy.
Normal to combination skin: Likely to appreciate the lightweight day cream and the glow-enhancing properties without excess oiliness.
Oily or acne-prone skin: Some users reported reduced oiliness; jojoba oil’s sebum-mimicking properties can balance skin. That said, richly occlusive night creams may feel heavy. Trial before committing or use the night cream sparingly.
Sensitive skin: The presence of fragrance in some formulations can be problematic. Niacinamide generally soothes, but patch testing is advised.
Mature skin concerned with fine lines: Hydration smooths the surface and reduces the appearance of fine lines. For deeper wrinkles, combine with proven actives like retinoids or in-office procedures if appropriate.

Product selection should align with specific skin conditions, tolerance to fragrance and the overall skincare regimen.

Value proposition and cost analysis

Avant’s bundle is presented as a premium offering: a day cream, a night cream and a vegan leather signature bag. The advertised regular price of £233 reduced to £99 represents a saving of £134. When assessing value, consider these factors:

Comparative pricing: Boots’ No7 Future Renew Dual Serum Regime is an alternative priced at around £119.95 for a set that includes multiple serums plus day and night creams. Medik8 and other specialist brands offer targeted active products at varying price tiers.
Cost-per-use: Many consumers judge value by jar size and longevity. Reviewers’ comments expressing a desire for larger sizes suggest enthusiastic users may find the standard jars run short on supply.
Experience vs clinical outcomes: If a product feels luxurious and encourages consistent use, it can deliver real, perceptible benefits. That experience should be weighed against the cost and the presence of cheaper alternatives providing similar actives.

For shoppers focused on hydration and daily comfort, the current promotion improves the value argument. For those seeking aggressive wrinkle reduction, the duo forms part of a broader, more active anti-ageing strategy rather than a standalone solution.

Alternatives worth considering

The market offers many alternatives that either expand on the active profile or target specific concerns.

No7 Future Renew Dual Serum Regime (Boots): A regimen that includes multiple serums alongside day and night creams, positioned for those who want concentrated actives plus moisturisers.
Medik8 Crystal Retinal: A retinoid-style product aimed at collagen stimulation and wrinkle reduction. Recommended for users ready to incorporate retinol-class actives. Start with lower strengths if you are new to retinoids.
Hyaluronic acid serums (multiple brands): Serums typically provide higher concentrations of HA and can be layered under any moisturiser to boost hydration on demand.
Cosmetic dermatology options: For deeper lines, in-office treatments such as lasers, microneedling or neuromodulators provide more dramatic results. Topical hydration supports recovery and maximises outcomes from such procedures.

Choosing between alternatives depends on tolerance for actives, budget and the balance between immediate hydration and long-term structural change.

Common pitfalls and what to watch for

Some limitations and practical issues warrant attention before purchase.

Jar packaging and contamination: Products in jars expose the formula to air and fingers, increasing contamination risk relative to pump packaging. Hygienic application tools (spatulas) reduce this risk.
Fragrance sensitivity: Some users enjoy scented skincare; others experience irritation. Check ingredient lists and, when possible, test on a small area before full-face application.
Overreliance on moisturisers: Hydration is crucial, but no moisturiser replaces daily sun protection, sleep, diet and other lifestyle factors that influence ageing.
Marketing interpretation: “Clinically proven” statements should be read with curiosity rather than blind acceptance. Look for the details of trials—duration, sample size and measured outcomes—when available.

A careful purchase decision balances sensory experience, ingredient efficacy and practical considerations such as jar size and packaging.

Packaging, sustainability and presentation

Avant includes a vegan leather signature bag with the duo. The bag adds perceived luxury and convenience for travel or storage. Considerations:

Vegan leather is an increasingly common alternative to animal-derived materials and appeals to many buyers on ethical grounds.
The environmental credentials of vegan leather vary by material and manufacture. Buyers concerned about sustainability should review material composition and company policies on sourcing and packaging.
Product presentation contributes to user satisfaction and the sense of value, which can influence consistent use and thus outcomes.

Packaging choices carry both functional and symbolic weight for consumers. They matter beyond aesthetics when they influence storage, hygiene and sustainability.

Practical buying tips and how to evaluate performance

When deciding whether to buy the duo, apply practical checks to judge fit and effectiveness.

Trial period: Start with the day cream alone for two weeks, then introduce the night cream. Photograph skin at baseline and at regular intervals to track changes objectively.
Layering test: Pair the day cream with your usual sunscreen and makeup to ensure no pilling and to confirm compatibility.
Patch test: Test a small amount behind the ear or on the inner forearm for 48 hours, especially if you have sensitive skin.
Track hydration vs structural change: Expect quick improvements in surface texture and hydration. Deeper changes in wrinkle depth or skin elasticity require longer use and often additional active ingredients.
Read diverse reviews: Look beyond glowing testimonials to find users with similar skin types and concerns. If multiple users with oily or acne-prone skin report improvement, that’s informative. If reviewers primarily describe short-term hydration, set expectations accordingly.

A methodical, evidence-informed trial is the best way to determine if the product suits you.

Case examples: how different users incorporated the duo

Three short, anonymised scenarios illustrate how the duo might be integrated.

Case 1 — Combination skin with early fine lines: A 35-year-old with combination skin replaces a heavy morning cream with Avant’s day cream. The light texture layers well under sunscreen and makeup, reducing midday shine. The night cream is used two to three times a week to prevent congestion. After six weeks the skin appears smoother around the mouth and eyes, with fewer visible lines on close inspection.

Case 2 — Dry, winter-prone skin: A 48-year-old with chronically dry skin integrates the night cream nightly and uses the day cream in the morning. Shea butter and HA reduce skin tightness overnight, and the individual reports fewer flakey patches within three weeks. They add a gentle facial oil on very cold nights for extra occlusion.

Case 3 — Oily, acne-prone but dehydrated skin: A 28-year-old with oily skin experiences a paradoxical “dehydrated yet oily” condition. They trial the day cream and find it stabilises oil production without causing breakouts. The night cream is used sparingly and only on dryer areas. Hydration improves and oiliness decreases in the mornings, making makeup application smoother.

These examples reflect how slight adjustments in frequency and layering can tailor results to individual needs.

Clinical context: what realistic anti-ageing goals look like

Hydration-based products deliver visible smoothing and comfort quickly, but long-term structural change requires additional strategies.

Short-term goals: Improved hydration, smoother texture, reduced fine-line appearance and less morning puffiness are reasonable to expect within days to weeks.
Medium-term goals (3–6 months): Continued use, combined with sun protection and compatible actives (niacinamide, peptides, retinoids), can improve skin tone, firmness and deeper wrinkle reduction to a limited extent.
When to seek professional treatments: Deeper wrinkles, significant volume loss or major texture changes may benefit from dermatological or aesthetic procedures. Topical hydration helps prepare and maintain results from clinical treatments.

Set expectations so that cosmetic success is measured in the right metrics: surface smoothness and hydration first, structural changes over time with a comprehensive regimen.

Final considerations before purchasing

Avant’s Ultimate Hydration Day & Night Duo presents a focused approach to daily hydration and overnight moisture retention, combining well-understood ingredients like hyaluronic acid, jojoba oil, shea butter and niacinamide. The current price promotion enhances value for shoppers seeking a ready-made day-and-night solution that includes treatments for the eye area.

Decide based on skin type, routine complexity and whether you prioritise immediate sensory enjoyment or concentrated, active-driven anti-ageing. Integrate consistent sun protection and evaluate the product over several weeks to see whether the hydrating effects persist and align with your skin goals.

FAQ

Q: Are these creams suitable for the eye area? A: Both the day and night creams are marketed as suitable for face and eye zones. They include hydrating and barrier-supporting ingredients that can benefit the periocular area. If you have extremely sensitive eyes or a history of reaction to fragranced products, patch testing or using a dedicated eye cream with targeted actives may be safer.

Q: Can I use the day cream in the evening and the night cream in the morning? A: You can, but the day cream is formulated to be lighter and more compatible with sunscreen and makeup. The night cream’s richer texture is designed for overnight occlusion. For oily or acne-prone skin, using the day cream at night may feel less heavy.

Q: How soon will I see results? A: Hydration and improved surface texture are often noticeable within days. Reduction in the appearance of fine lines and morning puffiness can appear within weeks with consistent use. More significant structural changes require longer-term use and additional active ingredients.

Q: Is hyaluronic acid safe to use with retinol? A: Yes. Hyaluronic acid and niacinamide are commonly used alongside retinoids to mitigate dryness and irritation. Introduce retinoids gradually and monitor for sensitivity, especially when combining multiple active products.

Q: Does “clinically proven” mean the product is clinically effective for everyone? A: “Clinically proven” indicates the product showed positive results in a controlled study or cosmetic trial, but results depend on study design, participant characteristics and endpoints. It does not guarantee identical results for every user.

Q: Should I worry about fragrance? A: Fragrance enhances the sensory experience for many but can irritate sensitive skin. If you have known fragrance sensitivity, perform a patch test or consult ingredient listings to confirm suitability.

Q: What are cost-effective alternatives? A: Hyaluronic-acid serums offer concentrated hydration at various price points. Boots’ No7 Future Renew regimen and Medik8’s retinal products represent alternative approaches—one emphasising multi-serum regimens and the other a more active anti-ageing route with retinoids. Evaluate based on priorities: immediate hydration, active-driven results, or a combination.

Q: How should I store the creams? A: Keep them in a cool, dry place away from direct sunlight. Because the creams appear to come in jars, use a clean spatula or wash hands before dipping into the product to reduce contamination risk.

Q: Is the promotional price a good deal? A: The reduced price from £233 to £99 is a significant discount, improving the cost-per-product ratio. Assess value relative to your usage pattern, whether you prefer separate eye creams, and how the formulations fit into your broader skincare plan.

Q: Will these creams reduce deep wrinkles? A: Hydration can soften the appearance of fine lines and improve skin texture, but deep wrinkles typically require a combination of topical actives (retinoids, peptides), consistent sun protection, and in some cases, professional procedures for more pronounced change.
