Sulfur in Skincare

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Sulfur in Skincare — a naturally occurring mineral used topically in cleansers, masks, and spot treatments to help manage acne, rosacea, and seborrheic dermatitis. It works mainly by gently exfoliating, absorbing excess oil, and reducing the growth of acne-associated bacteria and Malassezia yeast.

Key points

  • Sulfur is keratolytic, meaning it loosens and sheds dead surface cells that can clog pores.
  • It has oil-absorbing and mildly antimicrobial properties, making it useful for oily and blemish-prone skin.
  • Concentrations in over-the-counter products typically range from about 3 to 10 percent.
  • Sulfur has a distinctive odor and can be drying, so it is often paired with soothing or hydrating ingredients.
  • It is frequently used as a gentler alternative for people who cannot tolerate benzoyl peroxide or salicylic acid.

Frequently asked

Can sulfur be used with other acne actives?

Sulfur is often layered with other treatments, but combining multiple strong actives can increase dryness and irritation, so introduce them gradually. Consult a dermatologist before mixing sulfur with prescription products.

Is sulfur safe for sensitive skin?

Sulfur is generally well tolerated and considered relatively gentle, though it can cause dryness or a temporary odor. Patch testing first is a sensible precaution.
