Cosrx Refresh AHA BHA Vitamin C Booster Serum combines dual exfoliating acids with stabilized vitamin C to deliver comprehensive skin renewal. The AHA gently dissolves surface dead skin cells while BHA penetrates pores to address congestion and breakouts. Vitamin C brightens dull complexion and supports collagen production. This lightweight serum absorbs quickly without irritation, making it ideal for those seeking enhanced radiance and refined texture. Use 2-3 times weekly to reveal smoother, more luminous skin.
