Butt acne, often mistakenly referred to as such, is typically not true acne but rather folliculitis — an inflammation or infection of the hair follicles. This condition can manifest as small red bumps, pimples, or even painful cysts on the buttocks. The primary cause is usually the irritation and friction generated by tight clothing, prolonged sitting, or sweating, which traps bacteria, dead skin cells, and sweat in the follicles. Other contributing factors might include lack of proper hygiene or the use of irritating laundry detergents or personal care products.

Treating folliculitis on the buttocks involves several straightforward steps. Firstly, it's important to keep the area clean and dry. Showering after sweating and using a mild, fragrance-free soap can help. Wearing loose, breathable clothing, especially underwear made from natural fibers like cotton, also reduces irritation. Over-the-counter treatments such as benzoyl peroxide or salicylic acid can be effective in mild cases. For persistent or severe cases, it's advisable to consult a dermatologist who may prescribe antibiotics, antifungal creams, or other targeted therapies. Maintaining general skin health through hydration and a balanced diet can also support recovery.
