CosRx The Niacinamide 15 Serum with Acetyl Glucosamine & Zinc PCA (20g) is a highly concentrated serum designed to comprehensively tackle acne-related concerns, offering a clear and healthier complexion.

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. This formula unclogs pores, controls sebum production, and gently exfoliates, revealing smoother, blemish-free skin. Cruelty-free.

Directions of use:

• After cleansing apply a few drops to the skin.
• Use fingertips to gently massage and absorb the serum, starting from the centre of the face and working towards the edges.
• This serum can be used in the morning and/or afternoon.
• If applied in the morning, be sure to use it with an SPF of 30 or higher.
