Corsx niacinamide

Product Details

That’s *COSRX The Niacinamide 15 [/serum/]*, 20 mL/0.67 fl oz dropper bottle. *Short summary:* - *Use*: High-strength niacinamide serum for face - *Key actives*: 15% Niacinamide + Acetyl Glucosamine + Zinc PCA + Allantoin - *Claim*: Controls excess oil and sebum, minimizes the look of pores, and reduces congestion for a smoother complexion - *Texture*: Lightweight, watery serum that layers well without pilling - *Best for*: Oily, acne-prone, and combo skin types with enlarged pores or excess shine This is COSRX’s answer to The Ordinary’s 10% Niacinamide, but at 15% and with better supporting ingredients. Acetyl Glucosamine boosts niacinamide’s brightening effect on post-acne marks, while Zinc PCA regulates sebum. Allantoin keeps it from being too harsh. 15% is strong, so patch test first. Some people flush with high % niacinamide. Use AM or PM after cleansing, before moisturizer. Works well with most actives but skip layering with pure Vitamin C to avoid potential irritation.
