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."

"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."

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.
