Introduction
Tartaric acid has become a common ingredient in skincare products due to its keratolytic and astringent properties. It moisturizes the skin, stimulates the metabolism, promotes healing and it also has an anti-aging effect.
tartaric acid belongs to the class of alpha-hydroxy acids, also known as AHAs. Alpha hydroxy acids are naturally occurring substances found in both fruits and vegetables, and often boast powerful antioxidative properties. But in addition to that, alpha hydroxy acids are frequently used in skincare products such as cleansers or exfoliators, because they can remove dead skin cells from the surface of our skin.
