This common skin condition has the same causes as some forms of acne and therefore requires similar treatment. Sweat pimples occur when your pores get clogged with sweat, oil, and debris, which can promote inflammation and bacterial growth. Tight clothing can make things worse, causing friction between your skin and the fabric. As a result, it can lead to acne mechanica, a skin disorder characterized by small bumps, zits, and cysts in the affected areas. Excessive friction from clothing is also one of the reasons you get chest acne.
As far as treatment goes, consider switching to skincare products containing alpha- or beta-hydroxy acids, recommends Single Care. A formula with 2% salicylic acid can be effective, too. Apply these products to acne-prone areas after breaking a sweat. If, say, you normally get sweat pimples on your forehead, use a facial cleanser with one of the above ingredients. Apart from that, exfoliate your skin regularly to prevent clogged pores.
Another option is benzoyl peroxide, a topical medication for mild to moderate acne. "It is both antimicrobial, killing bacteria and other organisms, and an exfoliant, helping to unclog pores and gently debride the surface layer of skin," explained dermatologist Jessica Krant in an interview with Allure. For best results, choose a face wash or cleansing gel with 3% to 5% benzoyl peroxide. Start with a low concentration, especially if you have sensitive skin, and increase it gradually over several weeks.
