COSRX Snail Mucin + Niacinamide Dual Face Serum 80 ml — 74% Snail, 5% Niacinamide for Hydration & Radiance

This dual-action serum combines a high concentration of snail-derived mucin with 5% niacinamide to hydrate skin, even tone, and support resilience. The product uses two separate essences dispensed together — a clear liquid for moisture and a creamier phase for barrier nourishment — that mix on the skin for a lightweight finish without tackiness. Formulated to be hypoallergenic and dermatologist-tested, the COSRX formula emphasizes safe extraction practices and natural ingredients.

How does the dual-essence design work on my skin?

Pressing the pump releases both textures simultaneously so they blend at application, delivering the advantages of each phase in a single step. The clear essence penetrates rapidly to infuse moisture, while the creamier component helps seal hydration and support the skin’s protective layer.

• Two-phase pump dispenses balanced doses of liquid and cream
• Mix both textures on the palm before patting into skin
• Lightweight finish suitable for layering under moisturizer

What do the snail mucin and niacinamide actually provide?

The serum contains a triple-snail complex making up roughly 74% of the formula, paired with 5% niacinamide. Together, these ingredients supply sustained hydration, help improve the skin’s radiance, and contribute to a more even-looking complexion when used consistently.

• 74.3% triple snail complex for hydration and skin texture support
• 5% niacinamide to promote brighter, more even tone
• Combined to lock moisture in without a greasy residue

Will this serum feel heavy or cause breakouts?

The formulation is designed to be lightweight and absorbent; it delivers moisture deeply without leaving a sticky film. COSRX recommends performing a patch test first, and because the product is dermatologist-tested and hypoallergenic, many users find it compatible with sensitive and combination skin types.

• Light texture absorbs quickly, ideal for layering
• Hypoallergenic and dermatologist-tested to reduce irritation risk
• Patch test advised before full-face use to check for sensitivity

How do I incorporate this serum into my daily routine?

Use the serum after cleansing and toning, while skin is slightly damp, to maximize absorption. Press a small amount into the face and neck, then follow with moisturizer and SPF in the morning or a nourishing cream at night for best results.

• Apply after toner and before moisturizer for optimal layering
• Can be used morning and evening; always follow with sunscreen in daytime
• Mix the two textures in your palm before applying for consistent coverage

Who is this for: COSRX Snail Mucin 74% + Niacinamide 5% Dual Face Serum is suited for people seeking intensive hydration with a lightweight feel, those who want brighter-looking skin without heavy creams, and anyone who prefers a two-phase product that targets moisture and barrier support in one step. It’s appropriate for sensitive, dry, combination, and normal skin types when a patch test shows no irritation. Avoid use if you have known sensitivities to snail secretion filtrate or niacinamide, and consult a clinician for persistent reactions.
