What is beta hydroxy acid and how should it be used?

Beta hydroxy acid, also known as salicylic acid, aids in exfoliation, which results in clearer, fresher-looking skin. While similar to alpha hydroxy acids, beta hydroxy acid tends to be less irritating to skin while delivering similar improvements in skin color and texture. While mature and photoaged skin can benefit from products containing salicylic acid, it is particularly effective on congested or acne-prone skin because it is lipid (oil) soluble and can penetrate pores that contain built-up sebum (oil) and dead skin cells.
