Product Description

CosRx The Niacinamide 15 Serum (20g) is a high-strength niacinamide serum built to comprehensively tackle acne-related concerns, excess sebum, clogged pores, rough texture and post-blemish marks. With 15% Niacinamide supported by Acetyl Glucosamine and Zinc PCA, this concentrated Korean serum works towards a clearer, healthier complexion.

Niacinamide regulates sebum and helps reduce the look of scarring, while N-acetylglucosamine (NAG), Zinc PCA and Allantoin enhance its efficacy, unclogging pores, controlling oil and gently exfoliating to reveal smoother, blemish-free skin. Ideal for oily, acne-prone and congested skin.

Niacinamide, renowned for its sebum-regulating and scar-reducing properties, takes centre stage, while synergistic ingredients like N-acetylglucosamine (NAG), Zinc PCA, and Allantoin work together to enhance its efficacy. Cruelty-free.
