COSRX Niacinamide 5% + Snail Mucin 74% Dual Essence, a powerhouse serum designed to target multiple skin concerns—especially anti-aging and sensitivity.
What Is It?
The COSRX Dual Essence is a 2-in-1 serum featuring:
- Niacinamide (5%) – A form of Vitamin B3 known for brightening the skin, reducing inflammation, and minimizing pores.
- Snail Mucin (74%) – A hallmark ingredient in Korean skincare, known for its healing, hydrating, and anti-aging benefits.
Together, they form a lightweight, hydrating essence-serum.
Key Benefits
✨ Anti-Aging
Snail mucin is rich in glycoproteins, hyaluronic acid, and zinc—all of which support skin regeneration and smooth out fine lines.
🌿 Brightening & Oil Control
Niacinamide is a multitasking ingredient that helps reduce the appearance of dark spots, brightens dull skin, and balances sebum production.
💧 Deep Hydration
Despite its light texture, this serum deeply moisturizes the skin without making it greasy—perfect for dry, oily, or combination skin types.
🐰 Cruelty-Free
Like all COSRX products, this essence is not tested on animals, making it a compassionate choice for conscious consumers.
Who Should Use This?
This serum is particularly beneficial for:
- Sensitive skin types looking for non-irritating anti-aging solutions
- Oily or acne-prone skin due to niacinamide’s ability to regulate oil
- Dull or uneven skin tones that need brightening and smoothness
- Those in their 20s-40s wanting to start or maintain an anti-aging routine
