What is the primary ingredient in most exfoliators?

Alpha Hydroxy Acids (AHAs) are commonly regarded as the primary ingredient in many exfoliators due to their effectiveness in enhancing skin texture and promoting cell turnover. AHAs, which are derived from fruits and milk, work by loosening the bonds that hold dead skin cells together, allowing them to be sloughed off more easily. This process reveals fresher, smoother skin beneath and contributes to a brighter complexion.

AHAs are particularly prized for their ability to provide gentle chemical exfoliation, making them suitable for various skin types, including sensitive skin. They are known for their hydrating properties as well, which can help improve overall skin tone and texture.

While microbeads and salicylic acid are also used in various exfoliating products, microbeads have been largely phased out in many places due to environmental concerns, and salicylic acid is primarily known for its benefits in treating acne rather than for general exfoliation. Vitamin C is a potent antioxidant that helps with skin brightness and repairing but does not primarily function as an exfoliator. Thus, the selection of AHAs represents the most common and effective choice in the realm of exfoliating ingredients.
