Best sunscreen for fungal acne
For fungal acne, La Roche-Posay Anthelios Melt-In Milk Sunscreen SPF 60 is our pick for face and body. Fungal acne is driven by Malassezia, a yeast that feeds on many oils and fatty acids, so a sunscreen labeled oil-free and non-comedogenic is a sensible choice. This one gives broad-spectrum protection from four UV filters (avobenzone, homosalate, octisalate and octocrylene) in a light, fragrance-free milk. It is labeled water resistant for 80 minutes, which helps in heat and sweat, the conditions where Malassezia tends to flare. Protection starts as soon as it is on. Apply generously, reapply every two hours outdoors, and wash it off at the end of the day, ideally soon after heavy sweating, since trapped sweat can make fungal acne worse. If your bumps aren't improving after about 8 to 12 weeks, or sooner if they are painful or scarring, a dermatologist can prescribe treatments that over-the-counter products can't match.

Why it works
Broad-spectrum sunscreen (mineral and chemical filters)
Sunscreen, used with shade and clothing, helps lower the risk of skin cancer and early skin aging. Broad-spectrum products protect against both UVA and UVB rays, and SPF measures protection from sunburn. Dermatologists recommend broad-spectrum SPF 30 or higher, reapplied at least every two hours and after swimming or sweating. The evidence is strong: in a randomized trial of 903 Australian adults, daily sunscreen users showed no detectable increase in skin aging over about 4.5 years. Mineral filters (zinc oxide, titanium dioxide) are often recommended for sensitive skin. Some chemical filters are absorbed into the body, but absorption alone does not mean harm.
Managing Malassezia (fungal) folliculitis
Malassezia folliculitis, often called fungal acne, is an overgrowth of a yeast that normally lives on skin and feeds on skin oils. It causes itchy, uniform small bumps on the chest, back and face and is commonly mistaken for acne; it does not respond to antibiotics, which can make it worse. Heat, humidity, sweating and occlusive creams or sunscreens are triggers. Antifungal washes such as selenium sulfide shampoo or ketoconazole can help, but prescription oral antifungals work better. Evidence is limited to small studies. It often comes back, so weekly antifungal use and lighter products may help. See a dermatologist to confirm the diagnosis.
