The best sulfur spot treatments for acne combine 3-10% sulfur with absorbent ingredients like kaolin clay or calamine, applied only to active blemishes overnight rather than the whole face, since sulfur's drying effect can be harsh on surrounding skin if overused.
Sulfur has been used to treat acne for over a century, and it still holds up as a targeted option for inflamed, surface-level blemishes — it reduces oil and has mild antibacterial and keratolytic effects without the bleaching risk of benzoyl peroxide. It's not a substitute for a full acne regimen and won't do much for deep cystic breakouts, but as a fast, localized spot treatment it remains genuinely useful, sulfurous smell and all.
Sulfur concentration in the 3-10% range — higher isn't necessarily more effective and increases dryness and irritation risk
Whether it's formulated as a leave-on spot treatment versus a rinse-off mask, since usage and results differ
Absorbent co-ingredients like kaolin clay, calamine, or zinc oxide that help pull oil and calm redness
Fragrance or masking scent, since raw sulfur has a distinct smell some formulas disguise better than others
A plan to use it as a targeted spot treatment rather than all-over, especially if you're already using benzoyl peroxide or retinoids elsewhere in your routine
Best overall
Mario Badescu Drying Lotion
A cult-favorite pink spot treatment that combines sulfur with calamine and salicylic acid to shrink surface blemishes overnight. It only works if applied precisely to the settled sediment at the bottom of the bottle, not shaken in — skip it if you don't want to deal with that application ritual.
A straightforward 10% sulfur ointment with no added fragrance or frills, appealing to people who want the ingredient in its most basic form. The thick, medicinal texture and noticeable sulfur smell make it a harder sell for anyone sensitive to scent.
Dr. Sandra Lee's (Dr. Pimple Popper) brand pairs sulfur with a lighter, more cosmetically elegant base than older-school ointments, aimed at people who want the ingredient without a heavy medicinal feel. It's still drying, so those with already-parched skin should limit use to active spots only.

More modern, less greasy texture than traditional ointments
Peter Thomas Roth Therapeutic Sulfur Masque Acne Treatment
A rinse-off mask format that lets you treat several active blemishes or an oilier T-zone in one sitting rather than dabbing spot by spot. Because it's mask-format rather than leave-on, it's less suited to people who want continuous overnight treatment on a single stubborn spot.

Rinse-off, so less drying than leave-on options over time
Yes, for surface-level inflamed blemishes. Sulfur helps dry out oil, has mild antimicrobial properties, and gently exfoliates the top layer of skin, though it's generally less potent than benzoyl peroxide or salicylic acid for preventing new breakouts.
Can you use sulfur and benzoyl peroxide together?
You can, but it's not necessary and increases the risk of dryness and irritation since both ingredients are drying. Most people get better results using sulfur as a targeted spot treatment on nights they're not applying benzoyl peroxide to the same area.
Why does sulfur smell like rotten eggs?
Sulfur compounds naturally release a sulfurous odor, similar to rotten eggs, when they react with skin and air. Many modern formulas add fragrance to mask this, though some scent typically still comes through.
Is sulfur good for cystic acne?
Sulfur is better suited to surface-level, inflamed pimples than deep cystic acne, which usually needs prescription-strength treatment or in-office care since it originates deeper in the skin where topical sulfur has limited reach.
How long should I leave a sulfur spot treatment on?
Most leave-on sulfur spot treatments are designed to be applied at night and left on until morning, then rinsed off or simply washed away during your next cleanse — check the specific product's instructions since formulas vary.
