Exfoliation of the skin is a natural process where dead skin cells are released and replaced with new cell from the basal layer of the epidermis. Before the age of 30, skin cells turnover approximately every 28 days and decreases every year contributing to fine lines, wrinkles, and a dull, dry appearance. This is where manual or chemical exfoliation come into play, by increasing skin peeling in a controlled manner, resulting in a refined and smoother appearance. Manual or chemical exfoliation will benefit your skin to break down the upper layer of dead skin cells, if done correctly. When exfoliation is done excessively and or aggressively, it can cause inflammation and potentially damage your skin. Ask your skincare therapist on how often you should exfoliate. Be on the conservative side and it will benefit you in the long run, inflammation will cause aging.
