COSRX The Niacinamide 15 Serum
The COSRX The Niacinamide 15 Serum is a highly-concentrated serum that combines the maximum concentration of niacinamide with optimal ratios of synergistic ingredients for total acne and dark spots control. This serum also contains N-acetylglucosamine (NAG) to gently exfoliate skin and fade hyperpigmentation, while zinc PCA balances skin's oil-water levels.
Suitable for all skin types, recommended for oily and acne skin.

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