Body Acne and Back Acne: Causes, Treatment and Prevention

Acne on the back, chest and shoulders is extremely common, especially in hot and humid climates where sweat, friction from clothing, and clogged pores combine to create breakouts. Body acne can be just as frustrating as facial acne, but it often responds well to a focused, consistent routine.

What causes body and back acne

Body acne develops when sweat, oil, dead skin cells and bacteria build up inside pores, often made worse by tight clothing, sweating during workouts, and not rinsing off quickly afterward. Hair products, fabric softeners and heavy lotions can also contribute to clogged pores on the back and shoulders.

How body acne differs from facial acne

The skin on the back and chest is thicker than facial skin and has larger pores and more oil glands, which is part of why breakouts there can feel more stubborn. Body acne also tends to respond well to cleansing actives that can stay in contact with skin for a short time in the shower, rather than leave-on facial products.

Ingredients that help: salicylic acid and tea tree

Salicylic acid is an oil-soluble acid that can get inside pores and help clear the buildup that leads to breakouts, while tea tree is often used alongside it for its purifying properties. The Larupa Salicylic Acid Body Acne Soap combines both in a 75g bar designed for body and back use.

A simple body acne routine

1. Shower as soon as possible after sweating, especially after workouts.
2. Use the Larupa Salicylic Acid Body Acne Soap on affected areas, allowing it a moment of contact time before rinsing.
3. Avoid scrubbing hard, as friction can worsen irritation and spread breakouts.
4. For acne marks left behind, the Larupa 10% Niacinamide Face Serum with Zinc can be used on body areas to support an even tone once active breakouts have calmed down.

Habits that make body acne worse

• Wearing the same sweaty clothes for long periods.
• Using heavy, occlusive lotions on acne-prone areas.
• Sitting in wet swimwear or gym clothes.
• Picking or popping body acne, which increases the risk of marks and scarring.

When to see a dermatologist

If body acne is painful, cystic, widespread, or leaves deep marks or scarring, a dermatologist can offer treatments beyond what over-the-counter products provide. Persistent or worsening acne is also worth checking, since it can sometimes be linked to other underlying causes.
