Buttock Bumps That Look Like Pimples: Causes and Care

Pimple-like bumps on the buttocks are usually one of:

1. Folliculitis: Infected hair follicles (Staph, Pseudomonas from hot tubs). Red, tender pustules; itchy/burning.
2. Acne vulgaris: Comedones, papules, pustules, cysts; hormonal, friction, occlusion.
3. Boils (furuncles/carbuncles): Deep Staph infection; painful, fluctuant, may drain.
4. Keratosis pilaris: Rough, skin-colored/red bumps from keratin plugs; not true pimples.
5. Hidradenitis suppurativa: Chronic inflammatory nodules/abscesses in intertriginous zones; scarring, sinus tracts.
6. Contact dermatitis: Irritant/allergic reaction to wipes, detergents, fabrics.

Prevention & Care

• Loose, breathable cotton underwear.
• Shower promptly after sweating; gentle cleanser.
• Avoid tight synthetic clothing, prolonged sitting.
• Benzoyl peroxide wash (leave on 1–2 min) for folliculitis/acne.
• Warm compresses for boils; do not squeeze.

See a dermatologist if persistent, painful, scarring, or suspected hidradenitis.
