What is Beta Hydroxy Acid (BHA) also known as?

Alpha Hydroxy Acid
Citric Acid
Lactic Acid
Salicylic Acid

The correct answer is: Alpha Hydroxy Acid

Beta Hydroxy Acid (BHA) is commonly known as Salicylic Acid. This acid is oil-soluble and is frequently used in skincare products for its ability to penetrate the pores and exfoliate dead skin cells, making it a popular choice for treating acne and improving skin texture. Alpha Hydroxy Acid (AHA) refers to a different group of acids like glycolic acid and lactic acid. Citric Acid is another type of acid used in skincare products but is not synonymous with BHA.
