We Tried the Cult-Favorite Glamglow Supermud Clearing Treatment

At Byrdie HQ, we try a bunch of different products weekly, but only those yielding noticeable results earn a permanent spot on our vanities. There are those products, though, that earn a lot of hype before they even hit our desks. Case in point: Glamglow's beloved Supermud Clearing Treatment ($60). Countless celebrities have posted themselves in the cult-favorite gray Supermud mask, so we were excited to try it. Below, read our honest reviews.

Faith Xue, former editorial director

Faith's skin type: Oily

"The first time I used it, I applied the minty mixture all over my face and felt it working immediately. Three minutes later, I looked in the mirror at my greenish face and the little black dots forming rapidly like little colonies. My face had started feeling a bit like it was being stretched like the surface of a balloon and might burst at any moment, so I rinsed it off shortly after. When I peered in the mirror, my complexion looked smooth and bright—but also a bit like it had been wandering in the desert for a few days and was in desperate need of hydration (I slathered on Pestle & Mortar's Hyaluronic Acid Serum, $59, to quench its thirst).

Afterward, Byrdie's [former beauty director] Deven told me she only applies Glamglow's Supermud to her T-Zone, which I found to be a better technique. I only really need its vacuum-like abilities around that area, anyway. I use Glamglow's Supermud whenever my skin is looking (and feeling) particularly tired, and it immediately whips it in shape, like a mask version of Gunnar Petersen; my blackheads don't completely disappear afterward, but they are certainly less noticeable."

Lindsey Metrus, former associate general manager

Lindsey's skin type: Combination

"After using this mask a few times, it's become my emergency skin solution. Every time I notice my skin looks dull and broken out, I put the mask on, only to be met with greater clarity the following day. It's magic. Upon applying it, you feel an immediate minty tingle—the kind of tingle that makes you feel like it's really doing something. Then, as promised on the jar, once the mask dries to a lighter gray (or green, as Faith notices) hue, you can see it sucking the oil right out of your pores, as evidenced by the little specks of dark gray where your pores are being vacuumed. You can see it working before your eyes, which is the type of instant gratification I love in a skincare product.

I've even started using it as a spot treatment and leaving it on overnight when a major pimple has broken through my skin (not necessarily recommended for everyone, especially those with sensitive skin), but I've found that it dries up pimples quite literally overnight. Now I never have to panic again when my skin decides to go haywire."

Hallie Gould, senior editorial director

Hallie's skin type: Combination

"Despite all the hype surrounding this product, this was actually the first time I've ever tried it. Truth be told, I'm sitting at my desk with it on right now. The charcoal mud goes on and immediately feels minty, fresh, and tingly. As it drys, you can feel it pulsating through your skin (a cool side effect of the activated charcoal and clay). It's a little intense, but nothing beats being able to actually feel a product working. I washed it off after about 10 minutes (my skin felt too dry for 20) and noticed a significant reduction in my usual nose and chin congestion. Success! Because my skin is not particularly acne-prone, I'll probably use it every few weeks after a particularly late night or annoying cluster of breakouts."
