Beta Hydroxy Acid (BHA) is a type of exfoliant that is commonly used in skincare products to help improve the appearance of skin. BHA is a chemical exfoliant that works by breaking down the bonds between dead skin cells, allowing them to be easily removed from the surface of the skin. This helps to improve the overall texture and tone of the skin, as well as reduce the appearance of fine lines, wrinkles, and other signs of aging.
How BHA Works
BHA works by penetrating deep into the pores of the skin, where it breaks down the bonds between dead skin cells and oil. This helps to unclog pores, reduce the appearance of blackheads and whiteheads, and improve the overall texture and tone of the skin. BHA also has anti-inflammatory properties, which helps to reduce redness and inflammation associated with acne.
Types of BHA
The most common type of BHA used in skincare products is salicylic acid, which is derived from willow bark. Other types of BHA include citric acid, malic acid, and lactic acid. Each type of BHA has its own unique properties and benefits, and it is important to choose a product that is formulated with the appropriate type of BHA for your skin type and concerns.
Benefits of BHA

How to Use BHA

Be sure to use a sunscreen during the day if you are using BHA.
