Cosrx The Niacinamide 15 Serum 20ml

Cosrx The Niacinamide 15 Serum is a concentrated brightening and pore-refining serum that focuses on improving uneven skin tone, excess sebum, and visible pores. With a potent 15% niacinamide formula, it works effectively to control oil production while helping reduce the appearance of blemishes and post-acne marks. The lightweight texture absorbs quickly, making it easy to layer into any routine without feeling heavy or sticky.

Pair it with Cosrx Advanced Snail 96 Mucin Power Essence for enhanced skin repair and hydration.
