BHAs, or beta hydroxy acids, are a type of hydroxy acid used in skincare products to promote the skins natural exfoliation process. BHAs are oil-soluble, which means they can penetrate deeper into the pores to remove dead skin cells and excess sebum. The most common BHA used in cosmetics is salicylic acid. BHAs are effective in reducing the appearance of fine lines and wrinkles, improving overall skin texture, and treating skin conditions such as acne, psoriasis, and seborrheic dermatitis. BHAs can be found in a variety of skincare products, including cleansers, toners, moisturizers, scrubs, peels, and masks.

Its important to note that skincare products with BHAs may irritate the skin, bring on redness, or make you more likely to get a sunburn for up to a week after you stop using them. Its a good idea to talk to a dermatologist before trying an over-the-counter product with BHAs. If you want to use both AHA and BHA products for different skin problems, you should consult a doctor, as excessive skin irritation may worsen skin conditions and appearance.
