BHA (Beta Hydroxy Acid)
What Is a BHA?
BHA stands for beta hydroxy acid. A BHA is “a chemical exfoliant found within a variety of skincare products,” says board-certified dermatologist Dr. Sara Greer. That means BHAs can help remove dead skin cells from the surface of your skin. They are also commonly found in acne-fighting products. According to Dr. Greer, salicylic acid is the most popular BHA. Citric acid is another BHA that can be used in skincare products, though it is less common.
BHAs are used in a wide variety of beauty products, including makeup, hair and skincare. When it comes to skincare products, BHAs may be found on the ingredient list for serums, cleansers, moisturizers and more.
Since BHAs are chemical exfoliants, there are some potential downsides including “itching, peeling and sun sensitivity,” notes Dr. Greer. Applying sunscreen daily is especially important when using skincare products formulated with BHAs. Always remember to check with a board-certified dermatologist before testing out a new product or ingredient to make sure it is the right fit for you and your skin.
What Are the Skincare Benefits of BHAs?
“BHAs exfoliate and repair the skin,” says Dr. Greer. “They penetrate pores, dissolving sebum and clearing hair follicles of excess debris and dead skin. They also target and prevent blemishes.” Thanks to their exfoliating and blemish-fighting properties, BHAs can help you achieve a clearer, brighter and more refined complexion. Skincare products containing BHAs are a great choice for people with oily and acne-prone skin.
