COSRX Snail Mucin + Niacinamide Dual Face Serum, 2.7 oz — 74% Snail Complex, Lightweight Hydration & Brightening

COSRX Snail Mucin 74% + Niacinamide 5% Dual Face Serum is a two-texture facial essence that combines high-percentage snail mucin with niacinamide to hydrate and brighten skin while supporting the barrier.

This dual-face serum pairs a clear, lightweight essence with a creamy texture in one pump, releasing both at the same time for an easy, layered hydration step. Formulated with a 74% triple snail complex and 5% niacinamide, the product is designed to deliver moisture, a smoother surface feel, and improved overall radiance without heavy residue. COSRX emphasizes gentle sourcing and dermatological testing, and recommends a patch test before first use.

How does the two-texture delivery work for daily skincare?

The bottle dispenses two separate essences simultaneously: a clear, fluid layer and a creamier layer. When mixed on the fingertips they form a balanced serum that absorbs quickly, letting you follow with moisturizer or sunscreen without pilling.

• Two-in-one pump releases both textures together for consistent dosing.
• Clear essence: lighter, penetrative hydration for immediate comfort.
• Cream essence: richer finish to support the skin barrier and surface glow.
• Suitable for AM or PM routines before heavier lotions or oils.

What do the 74% snail complex and 5% niacinamide do in a routine?

The serum features a high concentration of a triple snail mucin complex alongside niacinamide. These ingredients work complementarily: snail-derived mucins lock in moisture and enhance texture, while niacinamide helps even skin tone and supports surface radiance.

• 74% triple snail complex includes land snail and two specialized mucin fractions.
• 5% niacinamide contributes to a smoother, more even-looking complexion.
• The combination focuses on hydration, texture refinement, and visual brightness.

Will this serum feel heavy or sticky on my skin?

The formula is engineered for lightweight hydration that absorbs without a tacky finish. Properly blending the two textures ensures the product layers well under creams or sunscreen and leaves the skin comfortable rather than heavy.

• Designed to sink in quickly for a non-sticky finish.
• Mix the clear and cream essences on your palm to create a uniform application.
• Works under makeup as a hydrating base when fully absorbed.

Are the snails harmed and is the product suitable for sensitive skin?

COSRX states the snail mucin is collected humanely in environments favorable to snails and processed for cosmetic use. The product is described as hypoallergenic and dermatologist-tested, but a patch test is recommended to confirm individual tolerance.

• Snail mucin collected in eco-conscious, cruelty-free conditions.
• Claims of hypoallergenic formulation and dermatologist testing.
• Patch testing for 24 hours is advised before full-face application.

Who is this for: This serum suits anyone seeking a concentrated hydrating essence that improves surface texture and radiance without heavy oils — useful for dehydrated, combination, or normal skin types looking to add targeted moisture and brightening support. If you have very reactive or allergy-prone skin, perform a patch test and consult a dermatologist if you experience irritation.
