Exfoliation involves physically scrubbing the skin with an abrasive. Mechanical exfoliants include microfiber cloths, adhesive exfoliation sheets, micro-bead facial scrubs, crepe paper, crushed apricot kernel or almond shells, sugar or salt crystals, pumice, and abrasive materials such as sponges, loofahs, and brushes. Facial scrubs are available in over-the-counter products for application by the user. People with dry skin should avoid exfoliants which include a significant portion of pumice, or crushed volcanic rock. Pumice is considered a good material to exfoliate the skin of the feet.
The exfoliating ingredient in most commercial big brand body washes products, are tiny particles of polyethylene, which are a hazard to marine life.
Chemical exfoliants include scrubs containing salicylic acid, glycolic acid, fruit enzymes, citric acid, or malic acid which may be applied in high concentrations by a dermatologist, or in lower concentrations in over-the-counter products. Chemical exfoliation may involve the use of products that contain alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs), or enzymes that act to loosen the glue-like substance that holds the cells together, allowing them to ease away.This type of exfoliation is recommended for people treating acne.
