COSRX Refresh AHA/BHA Vitamin C Booster Serum 30ml

Vitamin C plus daily-safe acids — for everyday glow. A watery booster serum with kiwi-derived AHA, dragon fruit BHA, and vitamin C — the daily glow layer for skin that can't tolerate stronger actives.

• Layers cleanly with hydrating toners and creams

Key ingredients:
