Betahidroxiácidos

Betahidroxiácidos, commonly known as BHAs, are a class of organic compounds characterized by a hydroxyl group on the beta carbon atom relative to the carboxyl group. In skincare, the most prominent BHA is salicylic acid, a derivative of aspirin. BHAs are oil-soluble, which allows them to penetrate the pores of the skin more effectively than their water-soluble counterparts, alpha-hydroxy acids (AHAs). This oil solubility is a key factor in their efficacy for treating acne and other oily skin conditions.

BHAs work by exfoliating the skin. They break down the bonds between dead skin cells, promoting shedding and revealing newer, healthier skin underneath. This process can help to unclog pores, reduce inflammation, and improve skin texture. Due to their ability to penetrate sebum, BHAs are particularly beneficial for individuals with acne-prone, oily, or combination skin. They can help to dissolve the mixture of oil and dead skin cells that contribute to blackheads and whiteheads.

Beyond their exfoliating properties, BHAs also possess anti-inflammatory and antimicrobial characteristics. These attributes further contribute to their effectiveness in managing acne breakouts and soothing irritated skin. While generally considered gentler than some AHAs, BHAs can still cause mild irritation, redness, or peeling, especially when first introduced into a skincare routine. It is often recommended to start with a lower concentration and gradually increase usage as tolerated. Sunscreen use is also essential when using BHAs, as they can increase skin sensitivity to sunlight.
