Beta-hydroxy acids (BHAs) are chemical exfoliants used in skin care products.
Understanding BHAs
BHAs are a type of acid that helps to gently remove dead skin cells. This process is called chemical exfoliation. It's different from physical exfoliation, which uses scrubs or other abrasive materials.
How BHAs Work
- BHAs work by dissolving the bonds that hold dead skin cells together.
- This helps to reveal fresher, brighter skin underneath.
- BHAs are often recommended for oily and acne-prone skin.
Comparison with AHAs

How to Use BHAs
- Start by introducing BHA products slowly into your routine.

In conclusion, BHAs are effective chemical exfoliants that offer several benefits for the skin, especially for those with oily or acne-prone skin. They work by gently dissolving dead skin cells and unclogging pores, leading to a clearer and smoother complexion.
