Summer Sweat & Breakouts?
Warmer weather and active lifestyles often lead to more sweating—and for many, that means frustrating skin breakouts. If you're noticing small, itchy, acne-like bumps on your chest, back, shoulders, or face, it might not be traditional acne. You could be experiencing Pityrosporum folliculitis, a common condition that thrives in heat, humidity, and sweat.
What Is Pityrosporum Folliculitis?
Pityrosporum folliculitis is caused by an overgrowth of Malassezia, a yeast that lives naturally on our skin. When sweat and oil build up—especially in the summer or after workouts—this yeast can multiply, inflaming hair follicles and causing red, itchy bumps that look a lot like acne but don’t improve with typical acne treatments.
Why Athletes and Summer Sweat Make It Worse
If you’re an athlete, gym-goer, or just sweating more due to the heat, your risk is higher. Tight workout clothing, friction, and delayed post-exercise cleansing can all contribute to flare-ups.
Tips to Prevent and Manage It:
- Shower immediately after workouts to remove sweat, oil, and yeast
- Use breathable, moisture-wicking fabrics to avoid trapping sweat
- Cleanse with CLn BodyWash, a gentle, dermatologist-recommended body wash designed to reduce bacteria and yeast buildup
- Spray SkinSmart Hypochlorous Acid Spray post-workout — it’s a non-irritating, antimicrobial mist that helps calm inflammation and reduce breakouts
- Avoid oily lotions or heavy products that clog pores
