Exfoliating ingredients are used in cosmetics and personal care applications in order to remove the dead cells of the skin and leave behind a smoother and fresher skin. Exfoliating ingredients stimulate blood circulation and increase the formation of new surface skin cells. Exfoliation can be done either by scrubbing the skin with natural exfoliants like oatmeal, rice bran etc. or with the help of chemicals like hydroxy acids, salicylic acid, retinol and other enzymes.
