Compatible with retinol, vitamin C, AHAs, and BHAs. Use as a buffering hydration layer to reduce irritation from stronger actives.
Those with mollusk or dust mite allergies may react to snail filtrate. Patch test on the neck for 24-48 hours before full face use.
Contains rosemary, eucalyptus, and thyme extracts — very sensitive skin may experience mild tingling on first use.
Ingredient breakdown
INGREDIENTSSnail Secretion Filtrate 83%Proven
The hero ingredient — also known as snail mucin. A complex mix of glycoproteins, hyaluronic acid, glycolic acid, copper peptides, antimicrobial peptides, and antioxidant enzymes (superoxide dismutase, glutathione s-transferase) that repair, hydrate, and regenerate skin.
- Clinical study: A 2008 Spanish clinical trial (Tribó-Boixareu et al.) on 100 patients with radiation dermatitis found statistically significant improvement in erythema, itching, and burning pain.
- Mechanism: A 2007 study identified antioxidant enzymes (SOD and glutathione s-transferase) as key drivers of snail mucin's regenerative properties.
- Benefits: Deep hydration, scar healing, barrier repair, fine line reduction, and improved skin elasticity.
Niacinamide 2%Proven
A gold-standard form of Vitamin B3 that multitasks to strengthen the skin barrier, regulate sebum, fade post-inflammatory hyperpigmentation, and minimize the appearance of pores.
- Source: Gehring, W. (2004) — Nicotinic acid/niacinamide is proven effective for pigmentation, fine lines, and sebum regulation.
- Concentration: 2% is well within the tolerance range (safe for sensitive skin, still effective for barrier support).
- Compatibility: Stable and non-irritating — pairs well with almost every active, including vitamin C, retinol, and acids.
Sodium Hyaluronate 0.4% (4,000 ppm)Proven
The low-molecular-weight salt form of hyaluronic acid. Holds up to 1,000 times its weight in water, delivering instant plumping hydration to the upper layers of skin.
- Function: Humectant that pulls moisture from the air into the skin.
- Synergy: Works alongside glycerin, propanediol, and betaine to create a multi-layered hydration system.
Panthenol (Pro-Vitamin B5) ~1%Proven
Converts to pantothenic acid (Vitamin B5) in skin. A soothing, healing, barrier-restoring powerhouse that is often used in post-procedure skincare and wound healing creams.
- Benefits: Reduces redness, calms irritation, speeds barrier recovery.
- Irritancy / Comedogenicity: 0/0 — safe for all skin types including sensitive and acne-prone.
Adenosine 0.04-0.1%Proven
A naturally occurring nucleoside (Korean Ministry of Food and Drug Safety approved anti-wrinkle active). Shown to improve dynamic wrinkles around eyes and forehead with consistent use.
- Clinical evidence: A high-quality clinical trial found topical adenosine at low concentration helped improve deep expression wrinkles.
Soothing Complex Multi-ingredientPromising
A blend of Beta-Glucan, Allantoin, Aloe Barbadensis Leaf Extract, and Dipotassium Glycyrrhizate (licorice root derivative) that work synergistically to calm redness, reduce inflammation, and strengthen the skin barrier.
- Beta-Glucan: Immunomodulator shown to be up to 20% more effective than HA at calming irritation.
- Dipotassium Glycyrrhizate: Potent anti-inflammatory that soothes reactive skin.
Organic Herbal Extracts Low %Promising
Certified organic blend of Rosemary, Witch Hazel, Eucalyptus, Thyme, and Rooibos extracts. Adds antioxidant, antimicrobial, and antibacterial support naturally.
- Rooibos & Rosemary: Rich in flavonoids and polyphenols that neutralize free radicals.
- Witch Hazel: Mildly astringent; helps with pore appearance.

Where it fits in your routine
ROUTINEUse as an essence after toner to prep skin and lock in hydration before heavier serums. Suitable for both AM and PM routines, every day.
How to use
HOW TO USECleanse & Tone
Start with clean skin. Follow with your favorite hydrating toner to balance pH and prep for better absorption.
Dispense 2-3 Pumps
Press 2-3 pumps into clean palms or directly onto damp skin. A little goes a long way — the 120ml bottle lasts 4-6 months.
Pat & Press
Gently tap and press into face, neck, and décolletage. Avoid rubbing to maximize absorption of the snail filtrate.
Layer Additional Products
Wait 30-60 seconds for the essence to fully absorb, then follow with serums, moisturizer, and (in AM) sunscreen.
Patch Test First
Apply a small amount to the neck for 24-48 hours before face use — especially if you have mollusk or dust mite allergies.
Who is it for?
WHOPerfect for you if:
- You have dehydrated, dull, or tired-looking skin
- You want to fade post-acne marks and uneven tone
- You have a compromised or sensitive skin barrier
- You're looking for an affordable snail essence with extra actives
- You want a lightweight, non-sticky hydration layer
- You're pregnant or breastfeeding and need a gentle routine
- You have acne-prone or fungal-acne prone skin
Consider alternatives if:
- You have a known mollusk or shellfish allergy
- You prefer vegan-only formulations (snail filtrate is animal-derived)
- You react badly to essential oil extracts (eucalyptus, thyme)
- You want fragrance or luxurious sensory experience
- You need a heavy cream for very dry skin (this is a lightweight essence)
- You want fast visible results (snail works gradually over 4-8 weeks)
Skin type compatibility
SKIN TYPESWatery gel texture absorbs quickly without adding shine. Niacinamide helps regulate sebum production and minimize enlarged pores.
Provides excellent hydration as an essence, but very dry skin will need a richer moisturizer or facial oil layered on top.
Balances oil and dry zones beautifully — hydrates without clogging the T-zone or suffocating drier cheeks.
Fragrance-free and alcohol-free, but the eucalyptus and thyme extracts may tingle on very reactive skin — patch test recommended.
Non-comedogenic (0/5), fungal-acne safe, and helps heal active breakouts while fading post-inflammatory marks.
Adenosine and snail filtrate target fine lines and elasticity. Best paired with retinol or peptides for stronger anti-aging effects.

Budget-friendly alternatives (dupes)
DUPESThe original K-beauty snail essence with 96.3% snail filtrate — slightly higher than Cos De BAHA. However, it lacks added niacinamide, hyaluronic acid, and panthenol. Texture is thicker and stickier. Cos De BAHA offers 120ml vs COSRX's 100ml.
80% snail filtrate in a thicker, more ampoule-like consistency. Smaller 30ml bottle (vs 120ml). Great for spot repair and healing, but less suitable as an everyday hydrating essence due to size and richer texture.
70% black snail mucin with centella asiatica and propolis. Thicker, more viscous than Cos De BAHA with stringy consistency. 50ml bottle vs 120ml — nearly 2.4x less product for a similar price point.
60% snail filtrate plus bee venom for anti-aging and acne benefits. Different focus — more targeted at acne-prone and mature skin. Lighter on overall hydration compared to Cos De BAHA's 83% formula.
Combines snail mucin with tea tree leaf water and centella. Stronger focus on acne-scar repair, with added fermented ingredients. Smaller 50ml size and slightly tackier finish than Cos De BAHA.
Not a true dupe — no snail mucin. But a cheap alternative for the hydration and panthenol benefits alone. Lacks barrier repair, niacinamide, and the regenerative peptides from snail filtrate.

Frequently asked questions
FAQYes — this serum is considered pregnancy and breastfeeding safe. It contains no retinoids, salicylic acid, hydroquinone, chemical sunscreens, or high-dose vitamin A derivatives. The formula is built around snail mucin, niacinamide (2%), panthenol, hyaluronic acid, and gentle soothing botanicals — all of which are regarded as safe during pregnancy by most dermatologists. As always, consult your OB-GYN or dermatologist if you have specific concerns.
Yes — this serum is fungal acne safe. It contains no fatty acids, esters, oils, or polysorbates that can feed malassezia (pityrosporum) yeast. The formula is water-based and primarily humectant-driven, making it a safe hydration layer for those prone to fungal acne or pityrosporum folliculitis. It has been widely recommended in the Simple Skincare Science (SkincareFAQ) fungal-acne safe community.
Yes — this essence layers beautifully with all common actives. It acts as a hydrating buffer that reduces irritation from retinol, AHAs, and BHAs. For vitamin C, apply vitamin C first (on dry skin) and follow with this essence. For retinol or acids, apply this essence first as a buffering layer, then apply your active. Snail mucin and niacinamide are both compatible with every major active and actually improve tolerance.
It works excellently for oily, combination, and acne-prone skin thanks to its lightweight gel texture and non-comedogenic formula. Dry skin types benefit from the hydration but should layer a richer moisturizer on top. Sensitive skin users should patch test first — the eucalyptus and thyme extracts may cause mild tingling in very reactive skin. Mature skin benefits from the adenosine and snail filtrate for elasticity support.
Immediate results include plumper, dewier, more hydrated skin from the first application. Calming effects on redness and sensitivity typically appear within 1-2 weeks. Visible fading of dark spots and post-acne marks usually takes 3-4 weeks of consistent daily use. Improvements in texture, fine lines, and overall skin elasticity develop over 6-8 weeks. For long-term barrier strengthening and anti-aging benefits, 3+ months of use is recommended.
This is an essence-serum hybrid that goes after cleansing and toning, but before your heavier serums and moisturizer. The order is: Cleanser → Toner → This Essence → Other Serums → Moisturizer → Sunscreen (AM only). Use 2-3 pumps on damp skin and gently pat in. Wait 30-60 seconds before applying the next product to allow proper absorption.
No — the serum has a comedogenic rating of 0/5. It is oil-free, silicone-free, and contains no known pore-clogging ingredients. The watery-gel texture is specifically designed to hydrate without occluding pores, making it safe for acne-prone and blemish-prone skin. Niacinamide actively helps minimize the appearance of enlarged pores over time.
The Period After Opening (PAO) is 12 months. Unopened, the product stays fresh for 36 months from the manufacture date. Most users finish a 120ml bottle within 4-6 months when using 2-3 pumps twice daily. Store in a cool, dry place away from direct sunlight to preserve the snail filtrate and niacinamide potency.
No — this serum contains Snail Secretion Filtrate, which is harvested from snails and is not considered vegan. However, Cos De BAHA is cruelty-free and does not test on animals. The snail mucin is collected through humane, stress-free methods. If you prefer vegan alternatives, consider products formulated with Galactomyces Ferment Filtrate or Centella Asiatica Extract instead.
The Cos De BAHA formula contains 83% snail mucin (vs COSRX's 96.3%), but adds 2% niacinamide, 0.4% hyaluronic acid, and 1% panthenol that COSRX lacks. The texture is lighter, more watery, and absorbs faster than the thicker, stringier COSRX essence. At 120ml vs COSRX's 100ml — and at roughly half the price — Cos De BAHA offers significantly better value. COSRX has the edge in raw snail concentration, while Cos De BAHA wins on formulation complexity and price.
Verdict: Cos De BAHA Snail Mucin Power Serum is one of the best-value K-beauty essences available today. With 83% snail secretion filtrate, 2% niacinamide, 4,000 ppm hyaluronic acid, and 1% panthenol packed into a generous 120ml bottle, it outperforms many pricier competitors on ingredient complexity and cost-per-ml. It hydrates, repairs the barrier, fades post-acne marks, and calms sensitive skin — all while being pregnancy-safe, fungal-acne safe, non-comedogenic, and fragrance-free. The only drawbacks are the slightly slimy texture (inherent to snail products) and the presence of eucalyptus/thyme extracts that may bother very reactive skin. A no-brainer holy grail for anyone looking for an affordable, multifunctional snail essence.

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.

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.
