Alfahidroxílicos

Alfa-hidroxílicos, commonly known as AHAs, are a class of chemical compounds characterized by the presence of a hydroxyl group on the alpha carbon atom, which is the carbon atom adjacent to the carboxyl group. This structural feature makes them organic acids. AHAs occur naturally in various fruits and milk, contributing to their inherent properties. In the realm of skincare and cosmetics, AHAs are widely recognized for their exfoliating capabilities. They work by weakening the bonds that hold dead skin cells together on the surface of the epidermis, facilitating their removal. This process can lead to smoother skin texture, improved skin tone, and a reduction in the appearance of fine lines and wrinkles. Common examples of alpha-hidroxílicos used in personal care products include glycolic acid, lactic acid, malic acid, and citric acid. The concentration and specific type of AHA can influence its efficacy and potential for skin sensitivity. When incorporated into skincare formulations, AHAs are often found in cleansers, toners, serums, and masks, and their use is generally advised with caution, especially when combined with sun exposure, as they can increase photosensitivity.
