Exfoliant is a term that is used in skincare and refers to a product or process that removes dead skin cells from the surface of the skin. However, there are several other words that can be used to describe the same thing. These words include scrub, peel, polish, buff, and slough. Scrub is often used to describe a physical product that contains abrasive particles or beads, while peel refers to a more chemical-based approach. Polish is used to describe a gentler approach to exfoliating that involves massaging the skin with a smooth surface. Buff and slough both describe the process of removing dead skin cells, with buff being a gentler option and slough being more aggressive. Ultimately, these words all describe the same thing: the act of removing dead skin cells to reveal fresher, brighter skin.
