The COSRX Lip Plumper is a multi-care lip treatment that gently exfoliates with AHA & BHA, brightens with Vitamin C, and hydrates with nourishing ingredients like shea butter. It also contains plumping agents (Volufiline & vanillyl butyl ether) that give lips a fuller, smoother appearance with a temporary tingling sensation. The balm-gel texture applies easily, leaving lips soft, refreshed, and revitalized.
