There are two main methods of at-home exfoliation: physical exfoliation and chemical exfoliation. Physical exfoliators contain tiny particles to lift and remove dead skin cells. In the natural space, it’s things like rice flour, walnut shell powder, or jojoba seeds. Many people prefer this type of exfoliator over others because you can control how strong the exfoliation is with the pressure you apply.
Chemical exfoliation, on the other hand, uses natural exfoliating acids such as hydroxy acids (AHAs, BHAs, or PHAs) or enzymes to gently dissolve dead skin cells. Mild chemical exfoliants can be surprisingly gentle and are good for dry and sensitive skin types (especially AHAs, which are hydrophilic acids), so if you have skin that’s easily irritated you You can look for a mild, low-concentration chemical exfoliant.
