Activated charcoal can be found in numerous cosmetic products, because it has a lot of positive effects. It helps to remove excess sebum, acne, impurities, and toxins from the skin, which is why it is a common ingredient in skincare routine (facial cleansers or facial masks). Shampoos can also contain activated charcoal, because it deeply cleanses the scalp and eliminates product residues from the hair. It is known that activated charcoal can whiten teeth and is used in oral hygiene products.
