Key Highlights

  • Yerin Ha anchors her skincare around ritual and gentle, K‑Beauty–leaning products: a rice-based cleanser, mugwort mask, BHA+PHA toner, and a botanical hyssop serum.
  • The routine blends calming botanicals with targeted acids and barrier‑supporting actives; frequency, layering, and skin type adjustments determine safety and effectiveness.

Introduction

Yerin Ha frames skincare as an act of self-possession: “This time is me time,” she tells the camera as a green, cooling mask covers her face. The Bridgerton star’s quick, intimate masterclass for Vogue reveals more than a stack of cult products. It charts a tidy philosophy—skincare as ritual—rooted in family habits, Korean beauty influences, and practical choices that travel easily between set and downtime.

Ha’s routine reads like a compact primer on contemporary K‑Beauty principles: gentle cleansing, targeted exfoliation, botanical calming, and lightweight serums. The items she reaches for—Tatcha’s Rice Wash, I’m From’s Mugwort Mask, Glow Recipe’s Watermelon Glow BHA + PHA Pore‑Tight Toner, and Arencia’s Glow Hyssop Serum—reflect both cross‑cultural ingredients and the hybrid formulation trends that dominate today’s skincare shelves. Her testimony is not a prescription for every skin type, but it offers a clear template: choose accessible products, respect the skin’s barrier, and treat skincare as a nonnegotiable moment of pause.

This article unpacks Ha’s routine, explains what each ingredient does, and translates her choices into a practical, evidence‑based framework. The goal is to give readers concrete guidance on how to adapt these products and principles to different skin needs—without gloss, hype, or unrealistic promises.

Where the Routine Begins: Cleansing with Rice‑Based Formulas

Cleansing is the foundation of any routine. Yerin Ha’s go‑to is a rice‑based cleanser, typified by the Tatcha Rice Wash she features. Rice has a long history in East Asian beauty practices—rice water and rice bran have been used traditionally for their smoothing and brightening effects—and modern formulations capture those benefits in more sophisticated ways.

How rice cleansers work:

  • Many rice‑based cleansers combine gentle surfactants with rice-derived powders or extracts (rice bran, rice starch, fermented rice), which provide a mild physical polish and soothe the skin.
  • Rice extracts contain amino acids and vitamins that can help support a smooth, even complexion without stripping natural oils.
  • These cleansers often leave a soft film that feels hydrating rather than squeaky clean, which helps protect the lipid barrier.

Practical use and considerations:

  • Frequency: Daily, morning and evening. Double cleansing—oil/balm cleanse followed by a rice or cream cleanser—is optional, depending on wear of makeup or sunscreen.
  • Skin types: Rice cleansers are suitable for normal, dry, sensitive and combination skin because they are typically low‑irritant. They can be too gentle for those needing stronger, medicated cleansers for active acne.
  • Real‑world example: Models and actors who cycle through heavy makeup often rely on an oil or balm first, then a rice or cream cleanser to remove residue while preserving the skin’s moisture.

Yerin Ha’s choice signals a priority: preserve the skin’s barrier while thoroughly removing impurities, a stance consistent with K‑Beauty’s gentle approach.

The Mugwort Moment: Calming, Anti‑Inflammatory Care

Ha applies I’m From Mugwort Mask during her ritual. Mugwort (Artemisia princeps and related species) is a botanical with a substantial footprint in Korean skincare. It has antioxidant and anti‑inflammatory properties that make it popular for soothing redness, calming breakouts, and supporting irritated skin.

What mugwort does:

  • Anti‑inflammatory and antioxidant activity can reduce visible redness and soothe stressed skin.
  • Rich in phytochemicals that may support barrier repair and help the skin recover after environmental stressors or cosmetic procedures.
  • Often used in wash‑off masks, sheet masks, and serums aimed at sensitive or acne‑prone skin.

How to use a mugwort mask well:

  • Frequency: One to three times per week, depending on formulation and skin tolerance. A wash‑off mask like I’m From’s is typically safe for weekly to twice‑weekly use.
  • Pairing: Follow with a lightweight moisturizer or serum to lock in hydration. Avoid combining intense actives (high‑strength retinoids or strong chemical peels) on the same day unless advised by a dermatologist.
  • Real‑world example: Someone returning from long travel or a shoot—situations that often aggravate barrier function—may use a mugwort mask as a quick reset before applying makeup or bedtime oils.

Mugwort offers a gentle route to calming without the side effects of stronger pharmacologic agents. For Ha, who describes skincare as a nightly pause learned from watching her mother, the mugwort mask functions both as treatment and ritual—an opportunity to “wash the day away.”

Exfoliation Without Aggression: BHA + PHA Toners

Ha includes Glow Recipe’s Watermelon Glow BHA + PHA Pore‑Tight Toner, a hybrid toner that pairs beta‑hydroxy acid (BHA, typically salicylic acid) with polyhydroxy acids (PHAs). That combination targets congestion and surface texture while reducing irritation risk.

Science and function:

  • BHA (salicylic acid) is oil‑soluble, penetrates sebum‑clogged pores, and exfoliates inside the pore to help clear blackheads and reduce breakouts.
  • PHAs (like gluconolactone) are larger molecules than AHAs and BHAs, providing gentle chemical exfoliation and delivering humectant benefits. PHAs are less likely to cause stinging or increased photosensitivity.
  • Together, BHA + PHA can refine texture and pores without the increased irritation associated with high‑concentration AHAs.

Usage guidance:

  • Frequency: Start with two to three times per week if you’re new to chemical exfoliants, and increase as tolerated. For experienced users, daily low‑concentration toners can be used, but monitor for dryness and sensitivity.
  • Layering: Apply after cleansing and before serums. If using active serums or retinoids, consider alternating nights to reduce irritation risk.
  • Patch test: Always test a new exfoliant on the forearm or jawline for 24 to 48 hours before full‑face use.
  • Real‑world example: A person with combination skin and occasional congestion might use the BHA+PHA toner nightly for a month to reduce clogged pores, then dial back to maintenance twice weekly.

Glow Recipe’s toner is emblematic of the mainstream pivot toward gentler chemical maintenance, enabling regular exfoliation without undermining barrier health.

Serums and Active Support: Hyssop and Brightening Actives

Ha’s serum pick, Arencia Glow Hyssop Serum, sits at the end of the core routine. Hyssop is an aromatic herb less commonly cited than niacinamide or vitamin C, but formulations like Arencia’s blend botanical extracts with established brightening or barrier‑supporting actives.

What hyssop brings:

  • Hyssop contains polyphenols and antioxidants that can protect skin from oxidative stress and promote a more even tone.
  • In practice, serums that feature hyssop are typically paired with niacinamide, peptides, or botanical hydrators to amplify brightening and maintain barrier integrity.

How to integrate a serum:

  • Order: Apply after toner/essence and before moisturizer. Serums target specific concerns—brightening, hydration, barrier repair—and should match your skin’s needs.
  • Frequency: Daily application is common for serums emphasizing brightening or barrier care. Some active serums (high‑strength vitamin C, for example) are best used in the morning with sunscreen; others (certain retinoids) are for night.
  • Example: For post‑shoot redness from makeup and lighting, a serum combining hyssop and niacinamide can help calm pigmentation and support barrier restoration.

Ha’s “drop or two” remark about the serum—she’s used it down to a few drops—underscores another practical truth: consistent, long‑term use, not dramatic one‑off treatments, often accounts for visible results.

Layering, Frequency and Skin Types: Translating Yerin Ha’s Routine

Yerin Ha’s selection is compact and adaptable. Translating it into a personal routine requires attention to layering order, frequency, and individual skin concerns.

A general morning routine inspired by Ha:

  1. Cleanse with rice wash (gentle).
  2. Tone with a hydrating or gentle BHA+PHA toner (if your skin tolerates it).
  3. Apply a lightweight serum (hyssop/niacinamide for brightening and barrier support).
  4. Moisturize with a cream or lotion suited to your skin type.
  5. Apply broad‑spectrum sunscreen (nonnegotiable when using chemical exfoliants).

An evening routine version:

  1. Double cleanse if wearing makeup/sunscreen: oil/balm then rice wash.
  2. Apply BHA+PHA toner (2–3 times per week for beginners; more often if tolerated).
  3. Use a calming mask (mugwort) 1–2 times per week, preferably on nights without strong exfoliants.
  4. Layer serum and then moisturizer or sleeping mask.

Adjustments for specific skin types:

  • Dry/sensitive: Skip daily BHA; use PHA formulations only. Use mugwort mask for soothing, and prioritize humectants (hyaluronic acid) and emollients.
  • Oily/acne‑prone: BHA is useful for pores and blackheads. Use a lightweight gel moisturizer and consider using the mugwort mask strategically for inflammation.
  • Combination: Use BHA on congestion-prone zones and hydrating serums elsewhere. The rice cleanser provides balance.

Timing and compatibility:

  • Don’t combine high concentrations of acids (strong AHA peels, high‑strength BHA toners) with intensive retinoids on the same night.
  • When introducing active ingredients, start slow: two nights per week for new actives, then increase frequency.
  • Always apply sunscreen in the morning when using chemical exfoliants to prevent photo‑damage and hyperpigmentation.

The Psychology of Ritual: Why “Me Time” Matters for Skin Health

Ha’s remark about watching her mother’s evening ritual—taking “a hot minute to wash the day away”—speaks to an unglamorous but pivotal element of skincare: ritualized consistency. Skincare routines do more than target pigmentation or fine lines; they establish a regular cadence of attention that benefits both skin physiology and mental well‑being.

Physiological benefits of ritualized skincare:

  • Consistent cleansing and barrier support decrease trans‑epidermal water loss, reducing dryness and sensitivity.
  • Regular, measured exfoliation improves cell turnover and maintains clarity, preventing the chronic inflammation that worsens acne and pigmentation.
  • Nighttime routines allow for occlusion and repair; the skin’s barrier and regenerative processes are most active overnight.

Psychological benefits:

  • A consistent routine creates a predictable, calming activity that can reduce stress and improve sleep hygiene—both of which influence skin health.
  • The act of tending to oneself signals a boundary between work (or set life) and personal downtime; for actors, who toggle between intense public exposure and private life, that boundary is stabilizing.

Real-world example: Actors and intensive professionals often report that consistent night routines—cleanse, hydrate, mask once a week—help them recover between shoots. For many, the benefits are practical (reduced makeup buildup and breakouts) and subjective (feeling prepared for the next day).

On Set and Off Set: Practicalities for Filming Schedules

Actors face unique skincare challenges: long hours under hot lights, heavy makeup, frequent travel, and fluctuating climates. Ha’s routine is compact—an advantage for life on set.

On-set strategies distilled from Ha’s approach:

  • Keep a compact kit: a gentle cleanser, a special mask for quick resets, a hydrating serum and a sunscreen for daytime.
  • Mask and treatment timings: Use soothing masks like mugwort during breaks when you can afford 10–20 minutes; reserve stronger actives for off‑shoot days.
  • Layer smartly: Makeup artists often use primers and heavier foundations for filming. Removing products with oil/balm cleansers followed by a rice wash preserves the skin’s moisture.
  • Travel adjustments: When flying, increase hydration steps (serums and mists), and consider barrier‑boosting moisturizers to offset cabin dehydration.

Example: A lead actor on a location shoot may cleanse thoroughly at the end of the day, use a calming sheet mask or wash‑off mugwort mask after makeup removal, and finish with a restorative serum. That sequence mirrors Ha’s emphasis on cleansing followed by calming and targeted treatment.

Buying strategy:

  • Start with the cleanser and sunscreen—those are the highest‑impact baseline products.
  • Add one treatment product at a time (toner or serum) and monitor skin response for 2–4 weeks.
  • Masks and specialty items are supplemental; they amplify but don’t replace core maintenance.

Ingredient Deep Dive: Mugwort, Rice, BHA, PHA, Hyssop, and Niacinamide

Understanding the active components in Ha’s routine clarifies how and why they work together.

Mugwort (Artemisia)

  • Properties: Anti‑inflammatory and antioxidant. Calms redness, supports repair.
  • Uses: Masks, serums, toners for sensitive and breakout‑prone skin.

Rice (rice bran/fermented rice)

  • Properties: Amino acids and vitamins support softness and hydration; some rice ingredients provide mild enzymatic exfoliation.
  • Uses: Creamy cleansers, powders, and hydrators. A good foundation for barrier‑preserving cleansing.

BHA (salicylic acid)

  • Properties: Oil‑soluble exfoliant that penetrates and clears pores. Anti‑inflammatory at low concentrations.
  • Uses: Toners, cleansers, spot treatments for acne and congestion.

PHA (gluconolactone, lactobionic acid)

  • Properties: Larger molecular weight acids that provide gentle exfoliation and humectant benefits; reduced irritation and less photosensitivity compared with AHAs.
  • Uses: Sensitive skin — an alternative to AHAs for those who react to glycolic or lactic acids.

Hyssop

  • Properties: Antioxidant and botanical support for brightening and calming. Less common but used increasingly in botanical serums.
  • Uses: As a supportive ingredient within serums targeting tone and radiance.

Niacinamide

  • Properties: Vitamin B3. Regulates sebum production, improves barrier function, reduces hyperpigmentation, and strengthens skin.
  • Uses: Serums and moisturizers. Compatible with most actives and safe for daily use.

Why these ingredients pair well:

  • A gentle cleanser preserves barrier integrity for acids to function without excessive irritation.
  • BHA clears pores while PHA provides surface renewal; the combination minimizes aggressive exfoliation.
  • Botanical calming agents like mugwort and hyssop counterbalance the possible dryness from acids.
  • Niacinamide supports barrier repair and brightening, helping maintain results over time.

Safety, Sensitivity and When to Seek Professional Advice

Skincare routines centered on chemical exfoliants and actives must be calibrated to skin tolerance. Avoid common pitfalls by following a few straightforward rules.

Patch test and introduce one new product at a time:

  • Allow 48–72 hours of observation for irritation. This reduces ambiguity if a reaction occurs.

Monitor for combined irritation:

  • Avoid layering multiple strong actives (e.g., high‑strength AHA + retinoid + BHA) in a single session.
  • If using a BHA toner daily, reduce frequency or swap to a hydrating toner if irritation appears.

Sun protection:

  • Chemical exfoliation increases photosensitivity. Daily, broad‑spectrum SPF 30+ is essential, and higher SPF is advisable for those using exfoliants frequently.

When to consult a professional:

  • Persistent redness, burning, blistering, or spreading irritation after product use.
  • If you have a chronic skin condition (severe acne, rosacea, eczema), ask a dermatologist before layering acids and botanical actives.

Real‑world cautionary tale: Enthusiasts sometimes “stack” multiple exfoliants to accelerate results. The short‑term effect may look superior, but chronic barrier compromise leads to rebound sensitivity, increased breakouts, and uneven tone.

Celebrity Routines and Realistic Expectations

Celebrity routines are often presented as secrets to emulate, but reality requires translation. Ha’s approach is modest: a few carefully chosen products and a clear ritual. That steadiness is the reproducible element, not the exact bottles.

Managing expectations:

  • No single serum or mask will erase deep pigmentation or dramatically rewind decades overnight.
  • Consistency yields the most reliable results. Using a gentle cleanser, measured exfoliation, targeted serums, and daily SPF over months produces skin changes that last.
  • Lifestyle factors—sleep, nutrition, stress, hydration—contribute materially to skin outcomes.

Comparative example: Many celebrities pair topical routines with in‑office procedures (laser, peels, injectables). Ha’s showcased routine focuses on accessible, at‑home care that anyone can adopt, which is precisely why it resonates.

Building a Balanced, Affordable Routine: A Practical Shopping Guide

To emulate Ha’s essentials without overspending, prioritize by impact and cost‑efficiency.

Priority purchases:

  1. Gentle cleanser (rice or cream) — foundation of barrier preservation.
  2. Broad‑spectrum sunscreen — prevents photoaging and hyperpigmentation after exfoliation.
  3. One targeted treatment (BHA toner or hydrating serum) — address your primary concern.
  4. Calming mask (mugwort or similar) — for inflammation reset.

Budget tips:

  • Start with an affordable toner or serum before committing to pricier boutique serums.
  • Look for drugstore or indie brands that offer BHA+PHA formulations and perform similarly for many users.
  • Masks are occasional buys—spend where you’ll use the product regularly.

Example plan:

  • Month 1: Buy gentle cleanser + SPF. Establish daily routine.
  • Month 2: Add BHA+PHA toner twice weekly, monitor response.
  • Month 3: Introduce a calming mask weekly and a brightening serum if needed.

This staged approach mirrors responsible skincare development and reduces the risk of adverse reactions.

Final Thoughts on Routine Longevity and Adaptation

Yerin Ha’s routine is notable not because it contains rare or exotic items, but because it’s deliberate. The philosophy is replicable: build a base that protects, add targeted actives sparingly, and let calming botanicals anchor the practice.

Adaptation advice:

  • Rotate stronger actives seasonally—more exfoliation in oilier months, more humectant and barrier focus in dryer months.
  • Travel with miniatures of cleanser, serum, and sunscreen to maintain consistency.
  • Reassess every 6–12 months; skin evolves with age, hormones, and lifestyle changes.

Ha’s anecdote about not practicing her British accent before landing the Bridgerton role underscores another truth about public personas: many appearances of effortless polish are the result of steady, unseen preparation. Skincare, like performance, rewards consistent, quiet work.

FAQ

Q: Can someone with sensitive skin use Yerin Ha’s routine? A: Yes, with modifications. Use the rice cleanser and mugwort mask for soothing care. Introduce the BHA+PHA toner slowly (once or twice weekly) and prioritize PHAs over stronger AHAs. Patch test each product and monitor for irritation; consult a dermatologist if you have inflammatory conditions like eczema or rosacea.

Q: How often should I use a mugwort mask? A: One to two times per week is typical. If your skin is inflamed or highly sensitive, once weekly may be best. Use it on nights when you’re not performing strong chemical exfoliation, and follow with a gentle serum and moisturizer.

Q: Is BHA+PHA safe to use every day? A: Many people tolerate daily, low‑concentration BHA+PHA toners, but start slowly—two to three nights per week—and increase according to tolerance. If dryness or redness develops, reduce frequency or switch to PHA‑only formulations.

Q: Can I layer niacinamide serum under azelaic acid or vitamin C? A: Niacinamide is very compatible with many other ingredients, including vitamin C and azelaic acid. If using vitamin C, apply it in the morning and niacinamide can go morning or night. However, when combining multiple actives, introduce one at a time and watch for irritation.

Q: Does rice cleanser brighten skin or just cleanse it? A: Rice cleansers primarily cleanse while providing a subtle polish from rice‑derived components. They can contribute to a smoother, brighter appearance over time by maintaining a healthy barrier and gentle exfoliation, but dramatic brightening is better addressed with targeted serums (vitamin C, niacinamide) and sun protection.

Q: What should I do if my skin reacts badly to a product? A: Stop using the product immediately, gently cleanse with a non‑irritating cleanser, and use a bland moisturizer. If symptoms are mild, monitor for a few days. Seek medical attention if you experience severe swelling, blistering, or pain, or if symptoms persist.

Q: How do I keep this routine affordable? A: Prioritize cleanser and sunscreen first, then add one active at a time. Many effective BHA/ PHA toners and niacinamide serums are available at mid‑range or drugstore prices. Masks and luxury serums can be purchased less frequently or as smaller sizes.

Q: Can men use these products? A: Absolutely. Skincare needs are determined by skin type and concerns, not gender. The same principles—gentle cleansing, measured exfoliation, targeted serums, and sunscreen—apply universally.

Q: Will following this routine guarantee “celebrity skin”? A: No product guarantees a particular look. Celebrity skin often combines consistent at‑home care, professional treatments, genetics, and makeup artistry. However, this routine supports barrier health, manageable texture, and a radiant baseline that serves well for both daily life and on‑camera work.

Q: Where can I buy these products? A: The products Yerin Ha uses are widely available online and in select retailers. Consider purchasing from reputable retailers or authorized brand sites to avoid counterfeit products. When trying new items, buy small sizes if available to test tolerance.
