Sulfur treatments for rosacea may help relieve redness, reduce inflammation, and promote exfoliation. Some sulfur treatments are available over the counter, while others must be prescribed by your doctor or dermatologist.

Rosacea is a chronic skin condition marked by persistent facial inflammation, redness, flushing, and broken blood vessels. On darker skin tones, it may appear dusky brown or yellowish-brown.

Oral medications, injections, and advanced electromagnetic wave-based therapies such as lasers and light treatments may help improve rosacea symptoms.

Topical sulfur treatments may also be a useful treatment if you experience rosacea.

Sulfur can be an effective treatment for some individuals with rosacea.

Sulfur combines anti-inflammatory and exfoliation properties, which may help:

  • calm redness and inflammation
  • promote skin turnover
  • reduce the presence of Demodex mites, tiny tick-like creatures that may be involved in rosacea

In a 2023 study of 47 Japanese participants with either erythematotelangiectatic rosacea or papulopustular rosacea, sulfur cream was found to be as effective as metronidazole cream (an anti-inflammatory antibiotic) over an 8-week treatment period.

The study found rosacea symptoms improved with both sulfur and metronidazole creams. However, the sulfur cream was more likely to cause contact dermatitis, or skin irritation, than metronidazole cream.

A common medication prescribed by doctors contains two ingredients: 10% sodium sulfacetamide (an antibiotic) and 5% sulfur. Research from 2022 suggests this combination improves redness and inflammation over 8 weeks of treatment.

Common drawbacks of sulfur creams, particularly when used as a treatment for rosacea, may include:

  • Odor: Sulfur has a distinctive and often unpleasant odor, often described as resembling rotten eggs.
  • Dryness: Sulfur may cause dryness, especially in individuals with naturally dry or sensitive skin.
  • Peeling: Sulfur’s keratolytic properties may promote exfoliation, potentially causing peeling or flakiness of the skin.
  • Redness: Some people may experience temporary redness or irritation at the application site. This is often a mild and temporary side effect.
  • Itching or burning sensation: Sulfur preparations may cause itching or a mild burning sensation, especially if you have sensitive skin. Minor irritation is generally temporary and may lessen with continued use.

If you experience worsening skin that does not seem to improve, stop using the product and contact your dermatologist for further advice. Though sulfur cream works for some people, not everyone will have the same response. It may be that sulfur does not work well for your skin, and you need a different treatment.

Where to get the best sulfur-based rosacea treatments

Over-the-counter sulfur products for rosacea are available in various forms, such as creams and cleansers. These are suitable for mild cases.

Prescription-strength sulfur creams, recommended by dermatologists, contain higher concentrations for more severe cases.

To choose the right sulfur product, consider:

  • the severity of your rosacea
  • your skin sensitivity
  • your personal preferences

For personalized advice, speak with a dermatologist who can recommend the best option based on your specific needs.

How often should you use sulfur soap for rosacea?

Generally, healthcare professionals advise starting with a lower frequency, such as once a day, and monitoring how your skin responds.

If your skin tolerates this, you may gradually increase your use. However, it’s important to follow the product’s instructions and consult with a dermatologist for personalized advice.

How long does sulfur take to work on rosacea?

The time it takes for the sulfur treatment to show results can vary among individuals.

Topical sulfur products can take several weeks to show noticeable results for rosacea. You may see improvement as early as 2–3 weeks, with more significant results often taking 6 to 8 weeks of consistent use.

Do you put sulfur on before or after moisturizer?

Healthcare professionals generally recommend applying sulfur-based treatments before moisturizing. This allows the active ingredients in the product to be in direct contact with your skin.
