If you've ever dealt with acne, rosacea, or persistently oily skin, you've probably tried a long list of cleansers — some too harsh, some completely ineffective. Sulfur is one ingredient I recommend frequently in my San Francisco dermatology practice, and it remains one of the most underappreciated tools in skincare.
Why Sulfur Works
Sulfur has been used in dermatology for over a century — and for good reason. It works through several mechanisms:
• Keratolytic action: It gently loosens the outer layer of dead skin cells, helping to unclog pores
• Antimicrobial properties: It reduces the bacteria (including C. acnes) that contribute to acne breakouts
• Anti-inflammatory effects: It helps calm the redness and irritation associated with rosacea flares
• Sebum regulation: It helps reduce excess oil without the aggressive drying effect of benzoyl peroxide or salicylic acid
This combination makes sulfur particularly useful for patients who have sensitive skin, rosacea, or who find stronger acne ingredients too irritating.
What Concentration to Look For
Effective sulfur washes typically contain between 3% and 10% sulfur. Lower concentrations (3–5%) are better suited to sensitive or rosacea-prone skin. Higher concentrations (up to 10%) are more appropriate for oily or acne-prone skin with good tolerance.
Over-the-counter products vary widely in quality. Look for a cleanser where sulfur is listed among the first active ingredients, not buried at the bottom of a long ingredient list.
How to Use a Sulfur Wash
• Use once daily to start — morning or evening
• Apply to damp skin, lather gently for 30–60 seconds, then rinse thoroughly
• Follow immediately with a non-comedogenic moisturizer — sulfur can be drying
• Avoid combining with other active ingredients (retinoids, benzoyl peroxide) until your skin has adjusted
• The sulfur scent dissipates quickly after rinsing — it should not linger
Who Should Use a Sulfur Wash?
Sulfur washes are well-suited for:
• Mild to moderate acne, particularly comedonal (blackhead/whitehead) acne
• Rosacea-prone skin with concurrent breakouts
• Oily or combination skin that doesn't tolerate benzoyl peroxide
• Patients with seborrheic dermatitis around the nose and brows
They are generally not a first-line option for severe cystic acne, which typically requires prescription therapy.
CCMD Sulfur Wash
I formulated the CCMD Sulfur Wash specifically for my patients dealing with acne and rosacea. It delivers effective sulfur concentration in a gentle base that won't strip the skin barrier — something I found was missing from many over-the-counter options.
It's available at carencampbellmd.com and works well as a standalone cleanser or as part of a broader acne or rosacea skincare routine.
As always, if you're dealing with persistent acne or rosacea, a consultation with a board-certified dermatologist is the best first step. Treatment is most effective when it's tailored to your specific skin type, triggers, and history.
