If you follow K-beauty at all, you have heard the word wonyoungism. It is one of those aesthetic terms that started in fan communities and spread fast, because it perfectly captures a specific look: glassy, luminous, impossibly hydrated skin that appears lit from the inside. Named after Jang Wonyoung of the K-pop group IVE, the trend swept Korean beauty culture in 2024 and 2025 and shows no sign of slowing down.
Wonyoung herself has become one of the most photographed young celebrities in Korea, and her skin has become something of a cultural reference point. In interviews, fan analyses, and beauty content across TikTok, YouTube, and Korean platforms like Naver and Pann, the question of how to achieve her particular brand of glowing, petal-soft skin has generated enormous conversation. The answer, according to skincare professionals and the fans who have reverse-engineered her routine, comes down to hydration layering, gentle but consistent care, and a firm commitment to avoiding anything that strips or dries out the skin.
This guide covers exactly what wonyoungism means as a skincare approach, why it works, and how to build the routine from the products available in our catalog.
What Is Wonyoungism?
Wonyoungism is not just a celebrity skincare routine. It is a broader aesthetic philosophy built around the idea that skin should look as close as possible to naturally perfect skin: intensely hydrated, plump, and radiantly dewy without looking oily, overdone, or painted. The comparison points are specific.
Glass skin is the foundational goal: that mirror-smooth, luminous texture where skin reflects light evenly. You achieve glass skin not through shimmer products but through true hydration, layers of water-binding ingredients that fill in the surface of the skin and make it look optically flawless.
Dewy finish is related but distinct. Dewy skin has a healthy, slightly moist appearance, like skin that has just been touched by morning air. This is the opposite of matte. In the wonyoungism framework, any product that mattifies or minimizes pores is working against the goal.
Plump, bouncy texture is what Korean beauty pros call "chok chok" skin, a term that basically means squishy and full of water. Skin with good moisture content literally has more physical volume. It bounces back when pressed. It fills in lines. The plumpness is a result of skin that is genuinely hydrated rather than just coated.
"Strawberry girl" or "milky skin" aesthetic describes the color and texture quality of ideal wonyoungism skin: flushed but even, soft and slightly creamy in tone, without redness, hyperpigmentation, or texture. Think unbothered, naturally perfect skin rather than the dramatic glow of highlight or highlighter.
How does wonyoungism differ from other current K-beauty trends? It is worth noting a few comparisons. Cloudism (inspired by BTS member Jimin) emphasizes a matte, poreless, almost airbrushed skin finish, minimizing all surface texture. Wonyoungism goes the opposite direction, embracing moisture and glow. Milky skin is an older term focused purely on creamy, even-toned skin without much attention to texture or luminosity. Wonyoungism synthesizes both while adding the specific glass-skin luminosity that defines Jang Wonyoung's look. It is the most holistically hydration-forward of the current K-beauty aesthetics.
The Core Wonyoungism Skincare Principles
Before getting into specific products and steps, it is worth understanding the underlying logic of this routine. Wonyoungism is not just a list of products. It is a framework for thinking about what your skin needs.
Hydration over everything
The single non-negotiable principle of wonyoungism is prioritizing hydration over every other concern. This does not mean ignoring actives entirely, but it does mean that if you have to choose between a stronger exfoliant and a more hydrating serum on any given night, the hydrating serum wins. Skin that is genuinely well-hydrated handles actives better anyway, the barrier is more intact, the recovery time is faster, and the overall texture is smoother, so this is not just an aesthetic preference but a practical skincare strategy.
Layering technique
Wonyoungism routines work through layering thin, watery products rather than relying on one heavy moisturizer to do all the work. The typical structure is: toner (first hydration layer), essence (second layer, often slightly more concentrated), serum (targeted treatment, ideally with humectants), and then a moisturizer to seal everything in. Each layer adds water-binding ingredients to the skin before the next layer is applied, and the cumulative effect is far more hydration than any single product could deliver alone.
Avoiding matte finishes
Any product that contains alcohol, astringents, silica (a common pore-minimizing ingredient), or kaolin clay is working against the wonyoungism goal. Toners should not tighten the skin. Moisturizers should not disappear into a matte finish. Sunscreen should not look powdery. Every product should contribute to or at minimum preserve the dewy finish.
Luminosity as the goal
The reason wonyoungism has become such a clearly defined aesthetic is that it has a specific visual outcome: you should look like your skin is glowing from within, not from highlighter applied on top. That internal luminosity comes from consistently hydrated, barrier-intact skin. It is the payoff for doing the routine correctly over time.
The Wonyoungism Skincare Routine
Here is how to structure a complete wonyoungism routine using products from our catalog, with morning and evening variations.
Morning Routine
Step 1: Cleanser
In the morning, skip the foaming cleanser. A quick rinse with water or a very gentle, milky cleanser is enough. Over-cleansing in the morning strips the moisture you built up overnight.
Step 2: First Toner (Hydration Layer 1)
Apply your first toner to damp skin. Pat it in gently with your hands rather than using a cotton pad. The goal is to start building water into the skin immediately.
Anua HEARTLEAF 77% SOOTHING TONER 250ml, $40.56
Soothing and hydrating with 77% heartleaf extract. Ideal for sensitive skin or anyone prone to redness. Apply first thing after cleansing and pat in completely before moving to the next step.
Anua Rice 70 Glow Milky Toner 250ml, $35.36
The milky, glow-boosting option. Rice extract gives the skin a luminous, almost creamy finish that aligns perfectly with the wonyoungism aesthetic. Great for normal to combination skin.
Step 3: Essence (Hydration Layer 2)
After your toner, apply an essence while the skin is still slightly damp from the toner. Essences are the cornerstone of Korean skincare hydration layering because they add a concentrated layer of skin-identical and fermented ingredients that prepare the skin for serums.
mixsoon Bean Essence 50ml, $39.85
Fermented soybean extract in a single-ingredient essence. The fermentation process makes the hydration more bioavailable to the skin, and the finish is soft and slightly luminous.
mixsoon Bifida Essence 100ml, $47.15
Bifida ferment is one of the best-studied ingredients for strengthening the skin barrier while improving overall radiance. The 100ml bottle lasts for months.
innisfree Green Tea Ceramide Milk Barrier Essence 90ml, $30.00
Ceramide-fortified with green tea extract for a milky, barrier-repairing essence that supports the dewy finish without any heaviness.
Step 4: Hydrating Serum
Your serum should be humectant-forward in a wonyoungism routine. This is not the step for a vitamin C or exfoliating acid. Save those for evening. Morning is for water-binding and plumping.
Anua PDRN Hyaluronic Acid Capsule 100 Serum 30ml, $37.44
PDRN (polynucleotide) plus 100% hyaluronic acid makes this one of the most intensely hydrating serums in the catalog. Niacinamide supports the barrier and reduces discoloration simultaneously.
Anua Birch Moisture Boosting Serum 30ml, $37.44
Birch sap is a lighter alternative to hyaluronic acid with strong humectant properties. The texture is extremely watery and absorbs instantly.
Step 5: Moisturizer
The moisturizer is the seal step. It locks in everything beneath it and provides the top layer of hydration. For wonyoungism, look for creams that dry down dewy or satin, not matte.
The AESTURA ATOBARRIER 365 Cream is one of the best-reviewed barrier creams in Korean dermatology. Its ceramide-heavy formula rebuilds the lipid layer, which is the foundation of healthy, luminous skin.
Anua Birch 70 Moisture Boosting Cream 50ml, $41.60
Birch sap, panthenol, and hyaluronic acid in a lightweight cream that gives a glass-skin finish without heaviness. Perfect for morning use when you want luminosity under sunscreen.
Step 6: Sunscreen (Dewy Finish)
Sunscreen is non-negotiable in any glass-skin routine. UV damage is the single biggest driver of texture irregularities, hyperpigmentation, and collagen loss, the three things that most undermine the wonyoungism look. Choose a sunscreen with a dewy, moisturizing finish rather than a powdery or white-cast formula.
Round Lab Birch Juice Moisturizing Sunscreen 50ml (SPF 50+, PA++++), $25.31
Round Lab Birch Juice Moisturizing Sunscreen is beloved in K-beauty circles specifically because it leaves a dewy, natural finish rather than the white cast or matte dryness of many SPF formulas. This is the closest thing to a sunscreen that feels like skincare.
Round Lab Birch Juice Moisturizing Tone Up Sunscreen 50ml (SPF 50+ PA++++), $22.06
A slight skin-brightening tone-up effect with the same birch juice moisture base. Adds a faint luminosity that contributes to the glass-skin look throughout the day.
Evening Routine
Step 1: Double Cleanse
Evening is when you can use a foaming or gel cleanser after an oil cleanser to properly remove sunscreen and makeup. This is the one step where more thorough cleansing is appropriate.
Step 2: Toner
Apply your toner again, using slightly larger amounts in the evening since you do not need to worry about anything sitting on top of it. This is also a good time to try skin flooding: applying multiple thin layers of toner and pressing each one in before applying the next.
Anua Birch 70 Moisture Boosting Toner 250ml, $29.12
The Birch 70 Moisture Boosting Toner is particularly well-suited for evening use when you want maximum hydration delivery. Birch sap absorbs quickly and lets you layer without feeling sticky.
Step 3: Essence
Continue layering with your essence of choice. In the evening, you can be more generous with application since the routine does not need to finish quickly before applying sunscreen.
Step 4: Serum (Targeted Treatment)
Evening is the right time for any actives you use: niacinamide, a low-percentage AHA, or a bakuchiol for cell turnover. The Anua PDRN Hyaluronic Acid Capsule 100 Serum 30ml works well here as a hydration treatment that also contains niacinamide for addressing any uneven tone overnight.
Step 5: Moisturizer and/or Sleeping Pack
In the evening, you can layer a richer moisturizer or apply your moisturizer as a sleeping pack (a slightly thicker layer applied as the last step). This creates an occlusive-adjacent effect that holds all the hydration in overnight.
ROUND LAB Birch Juice Moisturizing Cream 80ml, $37.75
ROUND LAB Birch Juice Moisturizing Cream is a well-priced, effective nighttime moisturizer that reinforces the birch sap hydration layered throughout the routine.
Anua PDRN Hyaluronic Acid 100 Moisturizing Cream 60ml, $33.69
PDRN and hyaluronic acid in a cream format for overnight skin repair. Pairs naturally with the Anua PDRN serum for a complete PDRN-focused evening routine.

Key Ingredients in the Wonyoungism Routine
Understanding the ingredients that power the wonyoungism routine helps you make smarter product decisions and troubleshoot when something is not working.
Hyaluronic Acid
Hyaluronic acid is the most well-known humectant in skincare. It binds up to 1,000 times its weight in water, pulling moisture into the skin from the surrounding environment (and from deeper skin layers, which is why applying it to damp skin matters). In the wonyoungism routine, you want hyaluronic acid in multiple products across multiple steps, not just in one serum. Look for it in toners, essences, and moisturizers as well.
Niacinamide
Niacinamide (vitamin B3) does several things that support the wonyoungism look. It strengthens the skin barrier, which reduces moisture loss. It reduces the appearance of pores, creating the smooth, even texture that glass skin requires. It addresses hyperpigmentation and uneven tone. And it does all of this without irritation, making it appropriate for morning and evening use on almost any skin type. The Anua PDRN Hyaluronic Acid Capsule 100 Serum 30ml is a particularly strong niacinamide-forward formula in the catalog.
Rice Water Extract
Rice water has been used in Korean and Japanese skincare for centuries. The starch, amino acids, vitamins, and minerals in rice water give it a unique combination of skin-brightening and hydrating effects. The Anua Rice 70 Glow Milky Toner 250ml is built around rice extract and delivers a slightly luminous, milky finish that directly supports the strawberry-girl skin aesthetic.
Birch Sap
Birch sap is a lighter, more elegant humectant than hyaluronic acid with a watery texture that absorbs almost immediately. It carries minerals, amino acids, and sugars that support hydration at the skin surface. The Round Lab and Anua birch lines are among the most popular wonyoungism-adjacent products in Korea because the texture is perfectly suited to layering: you can apply birch sap products multiple times without the heaviness that some hyaluronic acid formulas can leave.
Fermented Ingredients (Bifida, Bean Ferment, Galactomyces)
Fermented ingredients are a K-beauty specialty. Fermentation breaks down molecules into smaller sizes that penetrate deeper into the skin, and the fermentation process itself produces beneficial byproducts like natural acids and antioxidants. Bifida ferment is particularly valuable for barrier repair and radiance. The mixsoon Bifida Essence 100ml and mixsoon Bean Essence 50ml are both built around single fermented ingredients and deliver the kind of glow that comes from improved skin health rather than just surface moisture.
Ceramides
Ceramides are lipids that make up a significant portion of the skin's natural moisture barrier. When the barrier is healthy, it holds water in and keeps irritants out, which directly supports the plump, luminous look of wonyoungism skin. The AESTURA ATOBARRIER 365 CREAM 80ml is one of the most ceramide-rich formulas in the catalog, and it is widely recommended by Korean dermatologists for this reason.
Wonyoungism for Different Skin Types
One of the questions that comes up most often around this aesthetic is whether it works for every skin type. The honest answer: yes, but the approach needs adjusting.
Oily Skin
The biggest challenge for oily skin types is that a fully dewy finish can tip into looking greasy by midday. A few adjustments help significantly. First, use lighter formulas throughout: watery toners rather than milky ones, gel-type essences rather than cream essences, and a lighter gel or fluid moisturizer rather than a rich cream. Second, choose a sunscreen with a slightly less dewy finish, or use a birch-based sunscreen that controls shine while still maintaining moisture. Third, understand that oily skin is often actually dehydrated skin overproducing sebum to compensate for lack of water, so a consistent wonyoungism routine often reduces oiliness over time as the skin learns that it does not need to self-regulate as aggressively.
Dry Skin
Dry skin types benefit most directly from the wonyoungism approach. The layering routine is essentially designed for how dry skin absorbs and needs moisture. Key modifications: use the richest moisturizer in the lineup as the final step, consider adding a face oil or balm on top of your moisturizer in the evening, and do not skip the essence step since this is where dry skin gets the most cumulative benefit. The AESTURA ATOBARRIER 365 CREAM 80ml was specifically developed with dry and sensitive skin in mind.
Combination Skin
Combination skin requires a zone-based approach. In the morning, apply your toner and essence to the full face, but use a lighter moisturizer on the T-zone and a richer one on drier cheek areas. In the evening, you can be more uniform since you have time for the skin to absorb products properly. The birch-based products in the catalog work particularly well for combination skin because birch sap regulates moisture without clogging pores in oilier zones.
Acne-Prone Skin
Hydration is not the enemy of acne-prone skin. Dehydrated acne-prone skin tends to produce more sebum, which worsens breakouts. The key is choosing non-comedogenic formulas and avoiding anything with heavy silicones or occlusive oils that can block pores. The Anua HEARTLEAF 77% SOOTHING TONER 250ml is ideal for acne-prone skin because heartleaf extract specifically targets the inflammation response associated with acne. Layer lightly, and save any active treatments (like salicylic acid) for their own step rather than mixing them into your hydration layers.
Sensitive Skin
Sensitive skin types should lean toward the more calming end of the wonyoungism spectrum: the heartleaf toner, the green tea ceramide essence, and the AESTURA Atobarrier cream. Fermented products can occasionally trigger reactions in very sensitive skin, so introduce them slowly. Avoid fragrance wherever possible and patch test new products on the inner wrist before applying to the face.
Frequently Asked Questions
Is wonyoungism achievable for all skin types?
Yes, with modifications. The core principles, hydration layering, barrier-first approach, and dewy finish, can be adapted for every skin type. Oily skin may need lighter textures and a slightly less intensely dewy sunscreen finish. Acne-prone skin benefits from the routine's focus on barrier health, which reduces sebum overproduction over time. The only skin types that should approach it with extra care are those with confirmed fungal acne triggers, since some fermented essences can aggravate fungal breakouts.
How long does it take to get glass skin?
Most people see noticeable improvement in skin texture and radiance within 2 to 4 weeks of consistent wonyoungism-style layering. The plump, lit-from-within look that defines the aesthetic fully takes longer, roughly 6 to 12 weeks, because you are rebuilding the skin barrier and training the skin to hold more water. The more dehydrated or compromised your skin is at the start, the more dramatic the change will eventually be, though it takes longer to see.
What is the best toner for wonyoungism?
It depends on your skin type and what you want to prioritize. For sensitive or acne-prone skin, the Anua HEARTLEAF 77% SOOTHING TONER 250ml is the strongest choice: high heartleaf concentration, calming, and deeply hydrating. For a glow-first approach on normal to combination skin, the Anua Rice 70 Glow Milky Toner 250ml delivers the milky luminosity most associated with the wonyoungism aesthetic. For a lightweight, layer-friendly option that works across skin types, the Anua Birch 70 Moisture Boosting Toner 250ml absorbs quickly and stacks well with essences and serums.
Does wonyoungism work for acne-prone skin?
Yes, and it often improves acne over time rather than worsening it. Dehydration is a common driver of excess sebum production, which contributes to clogged pores and breakouts. A well-hydrated barrier is more resistant to the kind of inflammatory signals that trigger acne. The key is choosing formulas specifically suited for acne-prone skin, the heartleaf and birch lines from Anua are both safe for most acne-prone types, and avoiding heavy occlusives that can trap bacteria in pores. Focus on water-based hydration rather than oil-based sealing.
Wonyoungism vs. cloudism, what is the difference?
Cloudism, inspired by BTS's Jimin, targets a matte, flawless, poreless skin texture, almost like an airbrushed filter. It is the higher-coverage, lower-glow end of the K-beauty aesthetic spectrum. Wonyoungism is the hydration-first, glow-maximizing counterpart. They share the glass-skin goal of flawless texture, but they pursue opposite finishes: cloudism ends dewy hydration down to a satin matte, while wonyoungism leans into the dewy luminosity fully. In routine terms: cloudism uses more pore-minimizing, blur-effect products; wonyoungism avoids them.
