An exfoliator is a skincare product designed to remove dead skin cells from the surface of your skin. This process helps to reveal fresh, new skin underneath, making your complexion look brighter and smoother. Exfoliators can come in two main types: physical, which use small particles to scrub away dead skin, and chemical, which use acids like glycolic acid to dissolve the bonds holding dead cells together. Using an exfoliator regularly can improve the effectiveness of other skincare products, such as moisturizers and serums, by allowing them to penetrate deeper into the skin. However, it's important to choose the right exfoliator for your skin type and not to overdo it, as excessive exfoliation can lead to irritation or damage.
