Is this a cleanser or a treatment?
Both. The Clarifying Rosacea Formulaᴿˣ replaces your daily foaming wash, but the active ingredients — sulfacetamide sodium and sulfur — are doing medical work each time you wash. Lather onto damp skin, let it sit briefly while you finish your routine, then rinse. The contact time is what makes it work. Two cleansing steps a day means two treatment contacts a day.
Take the 3-minute assessment →Does it really smell like sulfur?
Slightly, yes — sulfur is the active ingredient, and there's no way around its faint smell. The good news: the smell rinses away and doesn't linger on your skin through the day. Patients who get past the first few uses usually stop noticing it entirely.
Can I use this if I'm allergic to sulfa medications?
No. Sulfacetamide sodium is part of the sulfonamide family — if you have a documented sulfa allergy, you should not use this product. A board-certified dermatologist on your care team will screen for this during your assessment. If you have a sulfa allergy, The Redness & Acne Formulaᴿˣ or The Advanced Redness Solutionᴿˣ may be appropriate alternatives for the rosacea-acne overlap.
Should I use this as my only rosacea treatment?
It depends on the severity of your case. The Clarifying Rosacea Formulaᴿˣ does significant work in the cleansing step, and some patients with milder rosacea-acne overlap do well on it alone. But most patients see better results when it's paired with a leave-on rosacea treatment that addresses persistent redness and reactive skin. A board-certified dermatologist on your care team will tell you whether to pair it with The Redness & Acne Formulaᴿˣ, The Advanced Redness Solutionᴿˣ, or use it on its own.
Can I use it with my current skincare?
Most of your routine can stay. Fragrance-free moisturizers, broad-spectrum SPF (essential for rosacea), and barrier-supporting products all pair well. What you should pause: other foaming or astringent cleansers, high-strength salicylic acid washes, and benzoyl peroxide products in the same cleansing step. If you're using a leave-on prescription rosacea treatment, apply it on dry skin after rinsing the wash off. A board-certified dermatologist on your care team will review your full routine during your assessment.
Can I use this if I'm pregnant?
No. Sulfacetamide sodium is not recommended during pregnancy or nursing. If you're pregnant, planning to be, or nursing, The Redness & Acne Formulaᴿˣ — built around azelaic acid — is the pregnancy-safe rosacea option in our lineup. If your pregnancy status changes during treatment, contact your DermClick care team immediately so your prescription can be adjusted.
