The 10% sulfur mask that clears the spots a wash alone can't reach.
Clinical Formula Therapeutic Sulfur Mask is a 10% precipitated sulfur mask layered over kaolin and bentonite clay — the dermatology-office standard for active acne, cystic breakouts, and oily skin. Apply a thick layer, leave 10–20 minutes, rinse. The mask version of what most clinical acne protocols use as a weekly intervention.
Why people reach for it
Sulfur is one of the oldest and most reliable acne ingredients. The 10% concentration is the high-impact dose — meaningfully more than the 3.5% versions sold over-the-counter.
Sulfur reduces the C. acnes bacteria, calms inflammation, and pulls excess oil from the pore — the trifecta that drives down active spot count.
Two clay systems pull oil and impurities out of pores while the sulfur does its antimicrobial work.
Regular use (1–3x weekly) noticeably refines pore appearance and reduces the surface texture that comes from oil-clogged skin.
Who it's for
For acne-prone, oily, combination, and breakout-prone skin:
Why it works
A clinically proven antibacterial and keratolytic — kills the bacteria that drive acne, absorbs excess oil, and breaks up the bond that traps dead cells inside the pore.
A gentle clay that draws oil and impurities to the surface without over-drying the skin around the spots.
A more intensive clay that absorbs deeper sebum and toxins — pairs with kaolin for a balanced clearing effect.
Adds a smoother application texture and contributes mild oil absorption.

Common questions
Is this the best treatment for cystic acne?
It's one of the most-recommended at-home interventions for cystic acne. 10% sulfur is high enough to deliver real clinical effect without prescription — and unlike topical retinoids or BP, sulfur is generally tolerated by sensitive and rosacea-prone skin.
Will it smell?
Yes — sulfur has a distinct rotten-egg smell. Most clients find it disappears within a few minutes of application. The smell is the active doing its work; there's no fragrance-free version of clinical sulfur.
Can I use it daily?
Yes for spot use, but full-face daily can be drying. Most clients land on full-face 2–3 times per week and spot use as needed.
Will it dry me out?
Some dryness is expected. Drop frequency if it's persistent. Always pair with a non-comedogenic moisturizer and daily SPF.
Is it safe during pregnancy?
Topical sulfur is generally considered low-risk during pregnancy and is one of the most-recommended pregnancy-safe acne ingredients — but always confirm with your OB or dermatologist.
Can I use it with retinol or BP?
Yes — sulfur layers well with most acne actives. Many clients alternate sulfur masking nights with BP/retinol nights for a comprehensive routine.

"The Therapeutic Mask is the in-between step between a face wash and prescription medication. For most clients with hormonal or cystic acne, weekly use of this mask is the difference between barely-controlled and clear skin. The smell is real. The result is also real."
