Your forehead has those tiny, itchy bumps that never come to a head — that’s not regular acne. That’s *Malassezia* yeast, and the $10 fix is sitting in the pharmacy aisle.
Dermatologists whisper about this sulfur mask because it’s the rare OTC that actually kills the yeast, not just calms the redness.
It’s a thick, yellow paste in a jar that looks like it belongs in a high school chem lab. Costs $9.98 on Amazon. The label just says “Sulfur 10% Ointment” — no fancy marketing fluff.
10% Precipitated Sulfur
The maximum OTC strength — any higher and it’s prescription-only
No Water Base
It’s a petrolatum-heavy ointment, so it stays put instead of evaporating
Zero Additives
No fragrance, no essential oils, no random botanical extracts that feed yeast

Sulfur breaks down into pentathionic acid on your skin — that’s the compound that nukes *Malassezia* on contact. It also loosens the keratin plug trapping the yeast, so it’s a double attack.
- Sulfur 10%: Dissolves into acid that kills yeast cells
- Petrolatum: Creates an occlusive seal so sulfur penetrates deeper
- Silica: Absorbs excess oil without drying out the moisture barrier
- Bentonite: Pulls out the gunk lodged in your pores

It smells like a burnt match dipped in a gas station bathroom. No way around it — the second it touches your nose, you’ll question everything. But it dries down to a chalky powder in 7 minutes.
Week two, the bumps on my temples flattened. Week three, the texture on my chin — where I get those tiny flesh-colored clusters — was actually smooth. The smell never goes away, but you get weirdly proud of it.

The bumps went from raised and itchy to flat and invisible in 18 days. The redness around my nose — still there. This isn’t a cure-all, it’s a targeted missile.

For fungal acne, this is the most effective thing under $15 — period. Just don’t plan a date night right after using it.
