What the gurus are saying

The mask's 10% sulfur concentration earns consistent praise for clearing acne, controlling oil, and unclogging pores without the harsh smell of other sulfur products. Dermatologists note it feels gentler than expected thanks to the kaolin and bentonite clays plus aloe vera, which means oily and acne-prone skin tolerates it well. Apply for 10 to 15 minutes until dry, then rinse thoroughly in the shower rather than wiping it off. Those with sensitive skin may want to patch-test first, and using it once or twice a week prevents over-drying.

"My favorite Peter Thomas Roth Sulfur Mask is really cool. If you are using the mask you're going to want to apply it, let it sit for about 10 to 15 minutes, that's how long it takes for it to dry, and then wash it off completely. Don't wipe it off with a washcloth because your washcloth and your entire laundry is going to stink for a hot minute. Rather hop in the shower, wash it off really good, and then use your barrier creams like La Roche Posay Cicaplast Balm on top to help heal that barrier."

"Sulfur kills yeast bacteria it will eliminate anything on your face. The downside to sulfur is that it really is stinky and a lot of people don't like the smell of it. I recently have been using the mask from Peter Thomas Roth. It's a 10% sulfur mask you apply it, leave it on 10 to 15 minutes until it dries, and then rinse it off. I would only recommend doing the mask maybe once a week so it doesn't irritate or dry your skin."

How to Shrink Large Pores: Dermatologist-Recommended Tips & Treatments | Dr. Aleksandra Brown
"I do like this in a mask form rather than a cleanser because mask is going to be more of a leave on so you have higher contact time compared to cleanser. The Peter Thomas Roth mask doesn't have that nasty smell it actually smells pretty good to me. You apply it leave it on for 10 to 15 minutes and rinse off it does not leave any residual smell whatsoever. The key benefits of sulfur is that it will help control the oil minimize clogged pores and reduce the shine it's also antibacterial so will help with acne as well as yeast and Demodex mites that we often get on our faces. If you suffer from acne seborrheic dermatitis or dandruff or rosacea it is ideal for oily and acne prone skin. If your skin is normal to combination I think you're still okay to try this mask however if your skin is sensitive you may want to do like a patch test before you use it on your entire face. The Peter Thomas Roth mask contains sulfur 10% which will help minimize the oil clear the clogged pores and its antibacterial properties will help with acne it also contains kaolin and Bentonite Clays which help draw impurities out from the pores further increasing the potency of the mask and aloe vera which will soothe and hydrate a little bit so you don't get too much irritation."

"Peter Thomas Roth has a Sulfur Mask that you can actually use as a mask and wash off too. His is a 10% Sulfur Mask with kaolin and bentonite clay to help absorb oil plus zinc oxide to calm your skin. It retails for $52 but it is 10% sulfur versus 3% of Kate Somerville, so I would urge you to try that one out if you cannot try the Kate Somerville. But if you're very sensitive and on the drier side maybe go for the Kate Somerville and not the Peter Thomas."

"Peter Thomas Roth has a $52 10% Sulfur Mask that does not stink unlike the D Cruz which really does smell bad. This one smells kind of like a spa. It is a clay mask with kaolin and Bentonite clays to help absorb excess oil and purify the skin. It also has aloe vera to help calm the skin down. So this is a great option for a full face of acne and one that I would say is really easy and really nice and hydrating and delicate on the skin. You don't feel like your skin feels over stripped when you use this."

"It's called the Peter Thomas Roth Sulfur Mask for acne. If you have acne and you do not have clear skin yet and you are not using a sulfur product, get this and try it out because sulfur is really the unsung hero in treating acne people overlook it all the time. You can use it a couple times a week. It helps unclog the pores and decreases some of that acne causing bacteria on the skin."
