Our take
Is Sulfur a Good Ingredient?
It rates Good because it has long-standing, clinically recognized keratolytic and antibacterial activity that helps reduce acne and excess oil with relatively reliable outcomes. Its performance can be limited by odor and a higher chance of irritation, so it doesn't reach Great, and appropriate concentration and usage matter.

Before you use it
Safety
It may cause dryness, stinging, or peeling, particularly on sensitive or compromised skin, so start slowly and patch test. In the U.S., sulfur is permitted as an OTC acne active typically around 3-10%, which guides safe use levels. Avoid layering initially with other strong exfoliants to minimize irritation.
