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.

"Peter Thomas Roth 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."
Sulfur: Underrated Ingredient for a Clear Skin! | Dr. Shereene Idriss
"Peter Thomas Roth right over here 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. As you can see 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."

"The one that I use is the Peter Thomas Roth Therapeutic Sulfur Mask. It does so well at absorbing excess oil and reducing inflammation. You can use it as a full face mask or just put it on like oily T-zone or just spot treat. I like to apply, let it sit for 10 to 15 minutes and then hop in the shower and rinse it off while I'm showering. The key ingredient here is the 10% sulfur, kaolin and bentonite clays and aloe vera. And while all sulfur is pretty stinky, I find this one to have no smell whatsoever after it's rinsed off and I do my skincare routine. I usually do it at night and when I go to bed, I smell nothing."

"I 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 a Dermatologist Manages Her Rosacea | Dr. Aleksandra Brown's Skincare & Treatment Plan
"Sulfur is a really great option for rosacea. It has antibacterial, anti-inflammatory, a little bit of antifungal properties, so it helps with those pustules, irritation, bumpiness. Really, it's my go-to. My favorite here is the Peter Thomas Roth Therapeutic Sulfur Mask. You guys have seen me use it for like so many things: rosacea, sebaceous oil glands, sebaceous filaments, acne around the hairline, you name it. I have found a use for this product. It works by absorbing excess oil and reduces inflammation. So you can use it as a full face mask or spot treatment. I tend to spot treat my whole face about once every 10 days. The key ingredients here are 10% sulfur which will visibly diminish blemishes. It has kaolin and Bentonite Clays. These absorb the excess oil and address the issue of clogged pores. It has a little bit of aloe vera which will help calm and soothe overtreated skin."

"My favorite here is the Peter Thomas Roth Therapeutic Sulfur Mask. It doesn't smell as bad as some of the other sulfur products that I've used. It helps absorb excess oil from the skin and can prevent clogged pores and reduce some of the shine. Sulfur also has that antibacterial action, so it will cut down on the amount of bacteria you have. I love it for acne, perioral dermatitis, or really just to keep pores clean, especially on the nose and the forehead areas. It's really ideal for that acne-prone, oily skin. If you're somebody with really dry, sensitive skin, it may not be your girl. I use it about once a week, and I use it pretty much to minimize the appearance of my sebaceous filaments. It's like that final final touch that my skin needs with the retinoid and salicylic acid. The key ingredient in this one is sulfur 10%. It does have some kaolin and bentonite clays and aloe vera. It doesn't smell amazing, no sulfur does, but I leave it on for 10 to 15 minutes, then hop in the shower and rinse it off in the shower and it doesn't smell like anything when I get out of the shower."

"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 on me, and then wash it off completely. Don't wipe it off with a washcloth or your washcloth and your entire laundry it's going to stink for a hot minute. Been there done that. Rather hop in the shower, wash it off really good, and then use your barrier creams, your LRP Cicaplast Balm on top or your Avène to kind of help heal that barrier."
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 sulfur mask contains 10% sulfur. I find it to be not too stinky, and the Peter Thomas Roth mask doesn't have that nasty smell that you get from sulfur, 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, 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 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 so you don't get too much irritation."

"The Peter Thomas Roth Therapeutic Sulfur Acne Mask is great for those with more oily combination skin because aside from the 10% sulfur it also contains niacinamide and bentonite clay that really helps to suck up some of the surface sebum and temporarily reduce surface shine, and at the same time with that sulfur helps to fight acne and inflammation in general. If you're using a sulfur mask I don't recommend using it more than like twice a week I think that is definitely sufficient, anymore it's going to cause irritation. [...] Sulfur is one of those things that are really nice to have as a good alternative but shouldn't be your first line for acne treatment. So if you're ready on an established acne routine like adapalene or prescription medications and wanting something a little extra that may help better improve your acne, I think this would be a nice one to incorporate. It also has some mild exfoliating properties and so great for temporarily reducing shine, maybe helping with clogged pores, and then you can also use it on your body as well and use that a few times a week to overall improve acne. It [...] can be a great complement to a well-established acne routine."

"Peter Thomas Roth sulfur mask for acne, I think it's like 30% off, but 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."

"If you have acne, rosacea, or seborrheic dermatitis, this might just be the answer that you are looking for. Sulfur is a major underrecognized superhero ingredient for the skin. Believe it or not, it treats so many conditions. This one is made very well. It has ten percent sulfur in it, and using it just a couple times a week can really give you an improvement for most people for a variety of skin conditions."

"Sulfur is just an under-utilized ingredient in skin care. Sulfur is antibacterial and it's anti-fungal so it's really great for skin conditions like acne, rosacea, fungal acne, or if you just have clogged pores or congested pores or you want a nice exfoliation from your skin. This has two types of clay in it which will help unclog the pores and help exfoliate the skin and the hero ingredient at this product is 10 percent sulfur and that is what is going to be doing all the hard work clearing up those skin conditions. You don't need to do this every day, I would say once or twice a week in your routine is really all you need. It's just something nice to switch up your skincare routine at night instead of using your retinoid product every single night. This is in the sale and it's probably the cheapest I've seen it all year long so definitely if you're interested in trying it out now is the time to buy this."

It also has two types of clay in it which is oil absorbing and will unclog the pores and it provides a gentle exfoliation. Choose the Peter Thomas Roth form if you have a bigger budget and want a stronger maximum strength product."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Sunscreen filters

Sun protection is the best evidenced way to slow visible ageing, and the filters are what does the work. Mineral and chemical filters both protect when a product is applied thickly enough and often enough, which is where most people fall short rather than on the choice of filter.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
