Loving this acne clearing mask. On the recommendation of my younger sisters, I picked some up on sale for $15 (regularly $30!!). Tiny 50 mL tube, which for the cost I find kind of stingy. Pale green clay based mask with 10% sulphur as the acne treatment. Works wonders on congested skin in my t zone (which has kind of become immune to benzoyl and salicylic) and doesn't smell totally awful while on your face. Afterwards, I get the occasional whiff of brimstone, but its not as overpowering as some sulphur treatments can be. Major warning, keep any cloth items you like even a little bit AWAY from this and away from your face. Clothes, linens, washcloths, towels, make sure they are old and ugly if they may come into contact with this. I made the mistake of using this before bed, and ruined a good pillowcase. The sulphur lingers long after washing the mask off, so do this in the morning, and plan to wash your face well before bed. This is a mask for your day off or the weekend, when you intend to veg out on the couch in your housecoat and endlessly watch arrested development on Netflix. I've also used it as a spot treatment overnight on a big ugly chin zit, and it worked great but was a little drying (use an old pillowcase!) Will definitely buy again when I run out, but only on sale.
