Exfoliators help keep the skin functioning healthily by encouraging the removal of dead skin cells from its surface. This then reveals the brighter, fresher skin below. Exfoliators can be physical, in that they use an ingredient which contains particles which scrub or buffer the skin’s surface, or chemical where an ingredient dissolves the chemical bonds holding the dead skin cells onto the skin’s surface, causing them to shed. Exfoliators can help with surface pigmentation and rough skin texture, as well as improving the effectiveness of the skincare you use as the products will be more evenly absorbed, and will sink in better. However be careful not to over exfoliate your skin and make it sore, especially with abrasive ingredients and scrubs.
