Exfoliating is a process of removing dead skin cells from the skin's surface, which can help improve skin texture and tone. There are two types of exfoliators: physical and chemical. Physical exfoliators include scrubs, brushes, and sponges, while chemical exfoliators contain ingredients such as alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs). Using good moisturizer for black skin is recommended. It is essential to choose an exfoliator that is gentle on the skin and does not cause irritation or redness.
