Description
COSRX The Niacinamide 15 Serum 20ml is a high-potency, maximum-strength clinical treatment specifically engineered to target chronic acne breakouts, minimize severely enlarged pores, and erase stubborn post-inflammatory hyperpigmentation. This advanced formula boasts an exceptional 15% concentration of pure Niacinamide (Vitamin B3), an optimal clinical dosage that systematically regulates overactive sebaceous glands to eliminate excess oil production and prevent future blemish formation. To complement this intense action, the serum incorporates Zinc PCA, a powerful mineral synergy that minimizes localized acne inflammation, clears out bacterial debris, and speeds up the healing of active breakouts. To counter the potential dryness associated with high-strength oil control, COSRX fortifies this treatment with a comforting blend of Allantoin and N-Acetylglucosamine (NAG). Together, these ingredients gently micro-exfoliate dead surface cells, fade persistent dark sun spots, and support skin regeneration. The lightweight, water-based fluid sinks instantly into the skin without leaving any sticky or heavy film, transforming oil-heavy, textured, and blemish-prone complexions into a remarkably smooth, uniform, and clear canvas.

Smooth the fluid gently over your face and neck, focusing heavily on problem areas like the T-zone, large pores, or active blemishes.

Follow up immediately with a lightweight, non-comedogenic moisturizer to lock in the active nutrients.

Exceptionally safe and recommended for use daily, during both your morning (AM) and evening (PM) skincare routines.
