Sulfur as an acne ingredient has a credibility problem and a smell problem. The credibility part is unfair — sulfur is one of the longest-studied and best-validated OTC acne actives, working on inflammatory lesions through three different mechanisms simultaneously. It softens and lifts surface dead skin, reduces sebum production, and has direct antimicrobial activity against the bacteria that drive acne flares. The smell part is fairer — older medical-grade sulfur lotions have a distinct eggy aroma that's a hard sell for anyone who isn't already committed. The Acne All-Star is Tula's attempt to keep the proven sulfur efficacy while solving for the wearability problem, and on most counts it succeeds.
That wearability point is exactly where the common dismissal — that sulfur treatments are too smelly and old-fashioned to bother with — deserves pushback. The odor is real but noticeably milder here than in the old-school lotions, and it dissipates within minutes of rinsing. More importantly, sulfur remains one of the better-tolerated OTC acne actives for the large group of people whose skin can't handle benzoyl peroxide or salicylic acid. Writing it off on reputation means passing over a genuinely useful option.
The 3-in-1 use case is the genuinely novel part. The same product can function as a daily cleanser (brief contact, mild action), a 5-to-10-minute mask (longer contact, more aggressive treatment), or an overnight spot treatment dabbed directly onto active lesions. The active concentration is the same in all three uses — what scales is the contact time. This is a smart bit of formulation thinking, because it lets users with mild ongoing congestion get maintenance benefits from the cleanser format while using the mask format only when they have active flare-ups. It's the opposite of the typical acne kit that requires three separate products and a complicated layering schedule.
The sulfur sits at the maximum OTC concentration of 3%, which is what gives it real efficacy. Around it is a supporting cast that's notably more thoughtful than what you find in older sulfur products. Bentonite clay and magnesium aluminum silicate handle the sebum-absorbing role and give the formula its mask-when-left-on functionality, complementing the sulfur's sebostatic action. Gentle sodium cocoyl isethionate and glycinate surfactants do the daily-cleanser work without stripping. Willow bark extract contributes a gentle salicin-derived keratolytic effect, and green tea brings EGCG, a polyphenol with documented anti-inflammatory and oil-reducing activity in acne research. And then there's the sprawling prebiotic-and-probiotic cast — lactobacillus and lactococcus ferments, plus inulin, alpha-glucan oligosaccharide, and a yacon root juice feeding the good bacteria — which is Tula's signature positioning and is genuinely interesting in an acne treatment actively disrupting the C. acnes population on the skin surface. Whether the probiotics are doing the work the brand claims is still an open research question, but the formulation logic is at least coherent. A long tail of fruit and botanical extracts and a chlorophyllin complex round it out, more brand flourish than function.
The texture is a thick beige-grey lotion that thins on contact with water, with a clay-like undertone you can feel from the bentonite. The smell is the legitimate caveat — there's a noticeable sulfur note when you first apply, which most users describe as eggy or mildly sulfuric. It dissipates within minutes after rinsing, but it's strong enough that some users will simply not enjoy the experience. This is a category-wide issue with sulfur products, and the Tula version is meaningfully milder than older medical-grade options without being odorless.
Results show up faster than you'd expect. Most users report visible reduction in active surface inflammation and oil within one to two weeks of consistent cleanser use. Cystic and inflammatory acne typically improves at four to six weeks. The product is not powerful enough for severe nodular or cystic acne — that usually requires prescription oral or topical treatment — but for mild-to-moderate inflammatory acne, mixed congestion, and, notably, the fungal-acne crossover cases that benzoyl peroxide doesn't reach, this is one of the better OTC options available. Its fungal-acne safety is a real differentiator, since sulfur has genuine anti-Malassezia activity that most acne cleansers lack.
The drying issue is real. Sulfur, even at well-formulated concentrations like this, can dry skin out over time, particularly if used as both a daily cleanser and a frequent mask. The smartest usage pattern is to alternate — daily cleanser most days, mask once or twice per week — and to follow with a hydrating, non-comedogenic moisturizer with niacinamide and ceramides. Users with already-dry or sensitive skin should treat this as an episodic mask only, not a daily cleanser, and skip stacking it with retinoids or strong acids on the same day.
The price is mid-range for the format. Thirty-two dollars for four ounces is more expensive than older drugstore sulfur products but less than most prestige acne treatments, and a tube lasts two to four months depending on how you use it. What you're paying for is the wearability, the cleaner ingredient surround, the brand's customer-experience polish, and the genuine usability of the 3-in-1 format. Its roughly 4,500 reviews averaging 4.3 back that up — fast results, versatile use, and less dryness than expected, with the smell and the premium price as the predictable gripes. For users who want serious acne care without committing to a five-step routine, this delivers more than its price suggests.
