Beta hydroxy acids (BHAs) are a type of exfoliant commonly used in skincare. The most well-known BHA is salicylic acid, which is derived from willow bark. BHAs work by penetrating the pores and dissolving excess oil and dead skin cells, making them particularly effective for oily and acne-prone skin. They help to unclog pores, reduce breakouts, and improve overall skin texture. In addition to their exfoliating properties, BHAs also have anti-inflammatory benefits. This makes them suitable for individuals with sensitive or acne-prone skin, as they can help calm redness and irritation. Regular use of BHAs can lead to clearer, smoother skin and a more even complexion.
