Anyone with acne
 knows there’s almost nothing we won’t try to clear our skin for good, 
but it looks like the answer might already be sitting in our medicine 
cabinet.

According to one Redditor,
 who goes by the name Samstrayed, applying a clay mask as a spot 
treatment and leaving it on overnight significantly reduces the size and
 redness of large pimples and totally erases smaller ones. Whoa.
Since the post, a slew of other users have chimed in with their own 
clay mask acne-cure stories, leaving us to wonder if this is for real or
 just a made-up internet sensation.
Well, our questions have been answered thanks to reporters at Allure along
 with the help of Joshua Zeichner, M.D., director of cosmetic and 
clinical research in dermatology at Mount Sinai Hospital in New York 
City, and Sejal Shah,M.D., a dermatologist in NYC.
[post_ads]According to Zeichner, a lot of products labeled as masks (especially
 any containing volcanic ash or high levels of sulfur) can actually be 
more effective when used as a leave-on skin treatment. “It may take time
 for active ingredients to penetrate and give their effect, so a full 
face treatment left in place for several hours may be of benefit for 
many products,” he said.
Shah added that the Redditor’s mask of choice, Innisfree Super Volcanic Pore Clay Mask,
 contains multiple drying agents (kaolin and bentonite clays in addition
 to volcanic ash), so it makes sense that it would help dry up any 
excess acne-causing sebum.
Who knew? So next time you feel a pimple coming on, it can’t hurt to 
try dabbing a bit of your favorite clay mask over the sucker before bed 
and washing it off in the morning. Sayonara, zits!
