Calms Redness
Centella asiatica, chamomile, and dipotassium glycyrrhizate soothe sensitized, reactive skin.
Anti-Aging
Adenosine is a Korean MFDS-recognized wrinkle-care active that supports smoother, firmer skin.
Antioxidant Complex
Black rice, sesame, eggplant, kelp, and green tea defend against environmental free-radical damage.
Safety & compatibility
SAFENo retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters. Generally considered safe to use during pregnancy and while nursing.
No fatty acids, esters, polysorbates, or oils that feed malassezia. A reliable choice for fungal-acne-prone skin.
Fragrance-free, essential-oil-free, alcohol-free. iUNIK holds Dermatest's highest hypoallergenic rating.
Pairs safely with retinol, vitamin C, AHA, BHA, and peptides — actually buffers irritation from stronger actives.
Rare, but those with shellfish or mollusk allergies should patch-test before facial use.
iUNIK does not test on animals (Dermatest certified hypoallergenic), but contains snail-derived ingredients.
Ingredient breakdown
INGREDIENTSBlack Snail Secretion Filtrate 70%Proven
The hero ingredient. Snail mucin is a natural complex of glycoproteins, hyaluronic acid, glycolic acid, copper peptides, and antimicrobial peptides — supporting hydration, wound healing, and collagen synthesis.
- Composition: Contains proteoglycans, glycosaminoglycans, hyaluronic acid, and copper peptides shown to support skin repair.
- Clinical evidence: A clinical study on radiation dermatitis patients found significant reductions in redness, itching, and burning when treated with snail secretion.
- Antioxidant action: Contains superoxide dismutase and glutathione s-transferase enzymes that neutralize free radicals.
Centella Asiatica Leaf Water 10%Proven
"Cica" — one of K-beauty's most studied soothing ingredients. Rich in madecassoside, asiaticoside, and madecassic acid, which calm inflammation and accelerate barrier repair.
- Wound healing: Triterpenoids in centella have been shown to support fibroblast activity and collagen synthesis.
- Anti-inflammatory: Reduces redness and irritation in sensitive and acne-prone skin.
Niacinamide ~2%Proven
Vitamin B3 — the multi-tasker. Strengthens the skin barrier, reduces transepidermal water loss, fades hyperpigmentation, and balances oil production.
- Barrier function: Boosts ceramide production for stronger lipid barrier.
- Korean MFDS: Officially recognized as a functional whitening active in Korea.
Adenosine 0.04%Proven
A nucleoside that signals skin cells to behave younger. One of only a handful of ingredients officially approved for wrinkle-care claims by Korea's MFDS.
- Clinical trial: Topical adenosine has been shown to reduce the appearance of deep expression wrinkles.
- Mechanism: Stimulates fibroblast activity and collagen production.
5 Black Superfood Extracts Botanical complexPromising
Black rice (Oryza Sativa), sesame, eggplant, kelp (Laminaria Japonica), and coffee — chosen for their dark anthocyanin and polyphenol content. Function as antioxidants and minor brighteners.
- Antioxidant load: Anthocyanins help neutralize free radicals from UV and pollution.
- Nutrient blend: Adds amino acids, minerals, and vitamins that support a healthy-looking complexion.
Soothing Botanical Trio Supporting activesPromising
Scutellaria Baicalensis (Chinese Skullcap), Polygonum Cuspidatum (source of resveratrol), and Cynanchum Atratum — a patented anti-inflammatory ingredient used in iUNIK's signature formulas.
- Skullcap root: Provides flavonoid-based antioxidant and anti-inflammatory action.
- Cynanchum atratum: Traditional folk remedy for inflammatory skin conditions.
- Resveratrol source: Polygonum cuspidatum is one of nature's richest sources of this antioxidant.
Sodium Hyaluronate & Glycerin Humectant duoProven
Two of skincare's most reliable hydrators. Pull water into the upper layers of skin for instant plumping and softness.
- Sodium hyaluronate: Lower-molecular-weight form of HA penetrates more easily than full-size hyaluronic acid.
- Glycerin: Decades of safety data, supports natural moisturizing factor (NMF) of the skin.

Where it fits in your routine
ROUTINEApply to clean, toned skin before heavier serums or moisturizer. Suitable for AM and PM. Great as a "first treatment" layer to prep skin for stronger actives.
How to use
HOW TO USECleanse and tone
Start with clean, slightly damp skin after toner — moisture helps the serum spread further.
Dispense 2–3 drops
A little goes a long way thanks to the 70% snail mucin concentration. Watch for the "snail trail" stringiness — totally normal.
Pat into face and neck
Gently press into skin with fingertips rather than rubbing, to encourage absorption.
Wait ~30 seconds
Let it sink in fully before layering moisturizer or other treatments.
Lock in with moisturizer
Always seal in with a cream or sleeping mask; in the AM, finish with broad-spectrum SPF.

Skin type compatibility
SKIN TYPESWatery, oil-free formula absorbs quickly without adding shine or congestion. Niacinamide helps regulate sebum.
Hydrating and humectant-rich, but you'll likely need a richer moisturizer or facial oil layered on top in winter.
Originally formulated with combination skin in mind — balances hydration without overwhelming oily zones.
Fragrance-, alcohol-, and essential-oil-free. Centella and chamomile actively calm reactive skin. Patch-test still advised.
Non-comedogenic, fungal-acne safe, low irritation potential. Snail mucin helps fade post-acne marks.
Adenosine and snail peptides offer gentle anti-aging support. Best paired with a richer night cream and SPF.

6K+ REVIEWSPros & cons
BALANCEDPraised
- Lightweight, watery texture absorbs faster than most snail products
- One of the highest snail mucin percentages on the market (70%)
- Pairs with niacinamide and adenosine in one formula
- Fragrance-, alcohol-, and essential-oil-free
- Excellent for sensitive, post-acne, and barrier-damaged skin
- Fungal-acne safe and pregnancy-friendly
- Affordable for the size and ingredient quality
Criticized
- Slightly stringy "snail trail" when dispensing from the dropper
- Not rich enough on its own for very dry skin in winter
- Glass dropper bottle is fragile for travel
- Visible improvements in pigmentation take 6+ weeks
- Not vegan due to snail-derived ingredients
Budget-friendly alternatives (dupes)
DUPESHigher snail concentration (96% vs 70%) but a much simpler formula — no niacinamide, adenosine, centella, or black superfoods. Slightly thicker, tackier feel.
Adds ginseng for additional anti-aging benefit. Lighter snail concentration but similar fragrance-free, gentle profile. Great if you want hanbang botanicals too.
Cream rather than serum format — richer, more occlusive, better for dry skin. Good if you prefer one all-in-one product over a layering routine.
Combines snail mucin with TrueCica complex (panthenol, madecassoside, adenosine). More targeted at acne-damaged barriers, slightly heavier finish.

Frequently asked questions
FAQYes — the formula is generally considered safe to use during pregnancy and while breastfeeding. It does not contain retinoids, salicylic acid, hydroquinone, or chemical sunscreen filters typically flagged for caution. Snail mucin, centella asiatica, niacinamide, and adenosine are all considered low-risk topicals. As always, run any new product past your OB-GYN if you have concerns.
Yes — the serum is fungal-acne safe. It contains no esters, polysorbates, problematic fatty acids, or oils that feed malassezia yeast. The arginine present is below thresholds typically considered risky in this water-based, oil-free formula, making it a reliable pick for fungal-acne-prone skin.
Yes — and many users actively pair it with stronger actives precisely because snail mucin and centella help cushion irritation. Apply your active treatment first, wait until it's absorbed, then layer this serum on top to soothe and rehydrate. It's particularly good as a buffer when introducing retinol or chemical exfoliants.
It's best suited to combination, oily, sensitive, post-acne, and dehydrated skin. Mature and dry skin types will love the actives but typically need a richer moisturizer or facial oil layered on top. Acne-prone skin benefits from the non-comedogenic, fungal-acne-safe formula.
Hydration and softness are immediate — skin feels plumper after the first application. Reduced redness and a calmer barrier are typically noticed within 1–2 weeks of consistent use. Visible brightening of post-acne marks, smoother fine lines, and more even tone usually take 6–12 weeks of daily AM and/or PM use.
Apply after cleansing, toner, and any watery essence — but before heavier creams, oils, and sunscreen. As a "first treatment serum," it preps skin to absorb everything that follows. You can use it both morning and evening, and it layers well under makeup thanks to its non-tacky finish.
No — we rate it 1/5 on the comedogenic scale. It's a water-based, oil-free formula with no problematic comedogenic ingredients. Snail mucin itself has a long track record of being non-comedogenic. The vast majority of users with acne-prone skin tolerate it without breakouts.
Approximately 12 months after opening, as indicated by the standard 12M PAO symbol on Korean skincare. Unopened, the product is shelf-stable for around 3 years from manufacturing. Store away from heat and direct sunlight, and discard if you notice any color change, separation, or off smell.
Verdict: iUNIK Black Snail Restore Serum is one of the most well-rounded snail mucin serums in K-beauty — combining a generous 70% concentration of black snail secretion filtrate with niacinamide, adenosine, and centella in a clean, fragrance-free, fungal-acne-safe formula. It's lighter and more wearable than COSRX's classic essence, and offers more active ingredients than most competitors at a comparable price. Best for sensitive, post-acne, combination, or dehydrated skin looking for daily barrier repair, gentle brightening, and subtle anti-aging support. Dry-skin users may want to layer it under a richer moisturizer.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
