Beta Hydroxy Acid

Beta hydroxy acid is reported to improve wrinkling, roughness, and mottled pigmentation of photodamaged skin after at least 6 months of daily application. Beta hydroxy acid found in skin-care products works best in a concentration of 1% to 2% and at a pH of 3 to 4.

The Difference Between Alpha and Beta Hydroxy Acids
The main difference between alpha hydroxy acids and beta hydroxy acid is their lipid (oil) solubility. Alpha hydroxy acids are water soluble only, while beta hydroxy acid is lipid (oil) soluble. This means that beta hydroxy acid is able to penetrate into the pore which contains sebum and exfoliate the dead skin cells that are built up inside the pore. Because of this difference in properties, beta hydroxy acid is better used on oily skin with blackheads and whiteheads. Alpha hydroxy acids are better used on thickened, sun-damaged skin where breakouts are not a problem.


Using a Beta Hydroxy Acid
Beta hydroxy acid is found in a variety of skin care products including moisturizers, cleansers, eye cream, sunscreen, and foundations.
