COSRX Refresh AHA BHA Vitamin C Lip Plumper is an innovative lip treatment that combines exfoliating acids and vitamin C to create fuller, smoother lips. This lightweight gel-cream formula provides gentle exfoliation while hydrating and plumping the lips for a more voluminous appearance. The product contains a blend of Alpha Hydroxy Acids (AHA) and Beta Hydroxy Acids (BHA) that work to gently remove dead skin cells while Vitamin C helps brighten and rejuvenate lip appearance. Users may experience a slight tingling sensation due to the plumping effect from Vanillyl Butyl Ether, which is normal for lip plumping products. The formula includes nourishing ingredients like Shea Butter and various botanical extracts to keep lips hydrated and healthy.
