COSRX The Niacinamide 15 Serum 20ml
Original price was: 2,400.00৳ .1,950.00৳ Current price is: 1,950.00৳ .
COSRX The Niacinamide 15 Serum is a high-potency treatment serum formulated with 15% niacinamide—a proven multitasking ingredient that helps brighten skin tone, reduce acne, control oil production, and minimize the appearance of pores. Ideal for acne-prone, oily, or dull skin, this serum also contains zinc PCA, allantoin, and N-acetylglucosamine (NAG) to boost skin barrier health while soothing irritation and refining texture.
Unlike many high-niacinamide serums that cause sensitivity, COSRX balances this formula with skin-calming and hydrating agents, making it effective yet gentle enough for regular use.
