|---|---|---|
| What it is | Not glamorous and not subtle — sulfur has a smell and it dries skin out. It earns its place in overnight spot treatments and clay masks, not in anything you leave on all over. | The current favourite for people who want something to put on a spot at 11pm without waking up to a peeling patch. Evidence is still thin compared with the established acne actives — treat it as a mild option, not a replacement. |
| Best for | Acne & breakouts, Oil control, Blackheads & sebaceous filaments | Acne & breakouts, Oil control, Blackheads & sebaceous filaments |
