Back acne has
different rules.
Research shows truncal acne affects over half of all acne patients, yet it's chronically underdiagnosed and undertreated. A study in Cosmoderma found that back and body acne have different triggers than facial acne, friction, clothing, and sweat occlusion play a much bigger role. Tracking these factors is essential because what works for your face may not work for your back.

Different skin, different triggers
Research shows truncal skin has a thicker stratum corneum, different sebaceous gland activity, and greater microbial imbalance than facial skin. A French survey of acne patients found stress (46%), high-fat diet (33%), and poor sleep (27%) were top perceived triggers for body acne.
Friction is a major factor
Acne mechanica, breakouts caused by friction, pressure, and heat, is especially common on the back and shoulders. Backpack straps, sports bras, tight clothing, and gym equipment all contribute. ClearSkin helps you track gear and clothing alongside breakouts.
Track body-specific triggers
ClearSkin logs daily habits that affect body acne: exercise type, clothing choices, shower timing after workouts, diet, and stress. Over weeks, patterns emerge that facial-acne advice would never reveal.
Monitor what's working
Changed your laundry detergent? Switched to looser gym clothes? Started showering immediately after workouts? ClearSkin's timeline shows whether each change actually improves your back acne or not.
Frequently asked questions
Why is back acne different from face acne?
Truncal skin has a thicker outer layer, different oil gland activity, and greater microbial diversity than facial skin. Clothing creates occlusion and friction that facial skin doesn't experience. Research published in the Journal of Cosmetic Dermatology found that treatments effective for facial acne don't always work for body acne, which is why tracking your specific back acne triggers separately is important.
What causes back acne?
The main triggers are friction from clothing and gear (acne mechanica), sweat left on skin after exercise, stress, high-fat diets, and poor sleep. Tight synthetic fabrics trap sweat and bacteria against skin, creating the perfect environment for breakouts. Unlike facial acne, which is often hormonal, back acne has a strong mechanical and environmental component.
How do I get rid of back acne?
Start by identifying your specific triggers through daily tracking. Common strategies include switching to breathable fabrics, showering immediately after sweating, using a body wash with salicylic acid or benzoyl peroxide, and changing sheets regularly. Research shows 15% azelaic acid foam is effective for moderate truncal acne. Tracking helps you see which changes actually work for your body.
Your back deserves tracking too.
Start logging your body acne triggers. What causes your back breakouts is probably different from what causes your face breakouts.
