Acne treatment

Sulfur

Also known as Sulphur

A time-tested acne ingredient that helps dry out blemishes, absorb excess oil and calm the look of redness. Gentle enough for many sensitive skin types.

What is sulfur?

Sulfur is a mineral used in acne care for generations. It has a mild drying and peeling effect and helps reduce the bacteria and excess oil that contribute to breakouts.

What it does for your skin

  • Helps dry out active blemishes
  • Absorbs excess oil for a less shiny finish
  • Calms the look of redness around breakouts

How to use it

A sulfur mask is the easiest way to use it. Apply a thin layer to clean skin, leave it on for the time on the label, then rinse. Start once or twice a week and adjust to how your skin feels.

Who it's for

Breakout-prone skin that also gets red or sensitive. Sulfur is often better tolerated than stronger acne treatments.

Common questions

How often should I use a sulfur mask?
Start 1 to 2 times a week. Some people use it more often during a breakout.
Can I use sulfur with salicylic acid?
Yes. Cleanse with salicylic acid, then use the sulfur mask. Watch for dryness.
