CosRx Refresh AHA BHA Vitamin C Booster Serum 30ml

CosRx Refresh AHA BHA Vitamin C Booster Serum (30ml) is a daily exfoliating serum formulated with natural brightening ingredients to improve skin tone and texture, refreshing and revitalising the complexion. Enriched with a 57% Golden Rx Complex of juicy Kiwi and Dragon Fruit extracts, it gently sweeps away dead skin cells while helping to reduce excess oil for a smoother, more radiant finish, making it ideal for combination to oily skin and anyone battling dullness or rough texture.

Free from parabens, alcohol, sulphates, mineral oil and artificial fragrance. Cruelty-free.
