COSRX The Niacinamide 15 Serum 20 ml

Transform your skincare routine with the COSRX The Niacinamide 15 Serum, a professional-grade, high-concentration treatment engineered specifically for oily, combination, and acne-prone skin types. This potent 20ml Korean beauty powerhouse serves as a “total acne care” solution, utilizing a maximum-strength 15% Niacinamide (Vitamin B3) concentration to effectively regulate excess sebum production, refine enlarged pores, and dramatically diminish the appearance of stubborn post-acne marks and hyperpigmentation. Clinically proven to deliver visible skin refinement in just four weeks, this lightweight and non-comedogenic formula targets blemishes at every stage—reducing whiteheads by up to 50% and blackheads by over 42%. By integrating synergistic actives like Zinc PCA and N-Acetylglucosamine (NAG), the serum not only prevents future breakouts but also smooths rough skin texture and strengthens the moisture barrier for a clearer, more radiant, and balanced complexion. How to Use Apply 2–3 drops to cleansed, toned skin, focusing on problem areas, and gently massage. Use morning and/or evening, and apply SPF during the day. Patch test before first use. Ingredients 15% Niacinamide, Zinc PCA (1%), Allantoin, N-Acetylglucosamine (NAG)
