AHAs and BHAs are two types of hydroxy acids that are commonly used in skincare products to exfoliate the skin and remove dead skin cells from the top layer of the skin. AHAs, or alpha-hydroxy acids, are water-soluble and work on the skins surface to improve the texture of the skin, reduce fine lines and wrinkles, and even out skin tone. Some common types of AHAs include glycolic acid, lactic acid, and citric acid. BHAs, or beta-hydroxy acids, are oil-soluble and can penetrate deeper into the pores to remove dead skin cells and excess sebum. BHAs also have antibacterial properties, making them effective for treating acne and other skin conditions. Salicylic acid is a common type of BHA. While both AHAs and BHAs are effective exfoliants, they have some differences in their properties and uses. AHAs are generally considered safe for all skin types, but they can make the skin more vulnerable to sun damage. BHAs are generally milder and less likely to cause irritation, but they may not be as effective for treating certain skin conditions as AHAs. Its important to read product labels and follow instructions carefully when using products containing AHAs or BHAs to avoid potential irritation or other side effects.
