BHA’s, or Beta Hydroxy Acids, are oil-soluble exfoliants that penetrate deep into the pores, making them perfect for oily and acne-prone skin. Unlike AHA’s, BHA’s work to clear out excess oil and dead skin cells from inside the pores, helping to prevent breakouts and reduce blackheads. They also have anti-inflammatory properties, which can calm redness and irritation. Regular use of BHA’s can lead to a clearer, smoother complexion with refined pores. As with all exfoliants, it's important to use sunscreen during the day to protect the skin.
