Exfoliation is a skin-care technique intended to remove dead cells from the top layer of your skin. By removing this layer of clutter off of your skin, exfoliation helps brighten your complexion, and lets your skin-care products penetrate deeper into your skin.
There are two types of exfoliation: mechanical and chemical
In mechanical exfoliation, a tool (like a Clarisonic brush or even a washcloth) or face scrub physically removes the dead skin cells. Chemical exfoliators, on the other hand, use ingredients like alpha- or beta hydroxy acids to dissolve cells.
The best method for you depends on your preferences, as well as what kind of skin you have.
