INCI: Sulfur
Sulfur is a long-used acne and oily-skin ingredient found in masks and spot treatments. What the evidence says and why the smell is part of the deal.

Sulfur masks and spot treatments are classics. They smell a bit, and they’re gentler than some people expect.
Sulfur has mild antibacterial and drying (keratolytic) effects. It’s often combined with sodium sulfacetamide in prescription products.
A Cochrane review of topical acne treatments found only limited, low-certainty evidence for sulfur compared with other options.
“Sulfur dries out a pimple overnight.”
It may calm a spot a little faster; it won’t clear acne by itself.
