The Shills Acne Purifying Peel-Off Black Mask ($11; amazon.com) is the internet's latest beauty obsession. On YouTube and Instagram, you'll find plenty of videos documenting the super-intense masking process. Unlike other masks that simply wash or peel off without much fuss, this charcoal-based peel seriously clings to the skin—and ripping it off hurts like crazy. It's weirdly mesmerizing to watch people pull the masks off and reveal the blackheads, dead skin, and other gunk hiding in their pores.

This video might be the funniest. It was posted on YouTube last week by YouTuber Tiff from Tee Cee Videos, and then made it to Facebook via Viral Thread. The Facebook video has already amassed 76 million views. (Warning: NSFW for swearing.)

In the clip, Tiff slowly peels off the the mask one painful millimeter at a time. "Oh God, it's rough. It's so rough," she screeches repeatedly throughout the peeling process, tears streaming down her face and her friend laughing hysterically in the background.

If videos like Tiff's are any indication, then this mask really does unclog pores. But considering all the pain and suffering involved, is it worth the hassle? And even more importantly, is it even safe? We reached out to two dermatologists to get their expert opinions on charcoal face masks like this one.

The good news: They’re safe. The bad news: using one is probably going to hurt. A lot. And it might irritate your skin, too.

“The mask 'sticks' to not just the blackheads, but also the skin and hair on the face,” says Melissa Piliang, MD, a dermatologist at the Cleveland Clinic. “When the mask is removed, it pulls off the outermost layer of skin and associated oils which serve as a barrier to protect the skin from the environment. This, plus pulling out the small hairs would cause significant pain—just like waxing the face.”

There are a few ways to make the peel-off process less painful. Washing your face beforehand helps to pre-exfoliate the skin, and removing hair also makes the mask removal more manageable, says Debra Jaliman, MD, a dermatologist in New York City. Both Dr. Jaliman and Dr. Piliang suggested applying the mask to only your T-zone or areas that have blackheads. The oilier skin in the center of the face may have a bit more protection from irritation, says Dr. Piliang. Dr. Jaliman advises not putting it on your entire face, especially if you have combination skin, which could be even more irritated by it.

You can expect the masks to help unclog pores and absorb environmental pollutants, oil, and dirt from the skin. Charcoal is especially good for people with acne and blackheads as it can help reduce excess oil, says Dr. Jaliman.

Still, Dr. Piliang warns that these masks, like any beauty product, can contain chemicals that can cause allergies or irritation. So be diligent about checking for ingredients that don’t work well with your skin, and be wary of buying through third-party websites, like Facebook, she says…

It's normal for frown lines to get deeper and more prominent as you age. Whether they pop up between your eyebrows, above your forehead, or around your eyes, these lines are usually a combined result of genetics, loss of collagen, and repeated facial expressions, New York City-based dermatologist Debra Jaliman, MD, told Health in a previous interview.

Of course, injectable fillers at your doctor's office can provide instant results, and topical creams can gradually soften the appearance of wrinkles over time. (We're partial to retinol serums such as Neutrogena Rapid Wrinkle Repair Serum and Roc Retinol Correxion Deep Wrinkle Night Cream.) But a simple, non-invasive tool could make a big difference, too—and it has the stamp of approval from thousands of online reviewers.

Presenting: Frownies. 

To buy: $20-$22; amazon.com, anthropologie.com, dermstore.com, and walgreens.com 

These vegetable-based adhesive patches are designed to be placed on top of your forehead where you have frown lines, gently pulling skin taut. With continued use, they help train your facial muscles not to make expressions that were contributing to fine lines, gradually softening their appearance.

"I'm 52 with fair skin and a serious-looking forehead… Oh, how I wish I had started using these ten years ago!" writes one reviewer. "After using them 3-4 times a week for a month, my frown line is about 75% gone."

Another reviewer raves about their fast results. "After only three nights of wearing the Frownies patch, the lines are smoothed, and only visible with the right lighting," she says. "HOW IS THIS POSSIBLE?"

Also good: Both fine lines and deeper wrinkles can benefit from the patches, reviewers say. "I am 30 and had pretty deep frown lines," writes yet another. "I started wearing these overnight between my eyes, and poof they are gone in the morning. I guess I was frowning in my sleep without knowing it? Whatever the reason, it looks like I got Botox."

Even better, this is one anti-aging solution that's seriously affordable. A $20 box of the original Frownies Forehead & Between Eyes patches contains 144 patches that are recommended to be worn for at least three hours at a time, so one box could last you for a few months if you wear them nightly.

Have lines in a different area of your face? The brand also sells patches for the corners of your eyes and mouth and specifically for lip lines.

Let’s be real, we know blondes don’t actually have more fun, especially during fall, which is when dark manes really shine. There are countless ways to add dimension to a traditional brunette ‘do, and the change in season is the perfect excuse to transform your tresses. From copper highlights to flannel hair, we’ve gathered nine fall color trends for brunettes you’re going to be seeing everywhere this season.

Before you head to the salon, it's important you know how to care for newly dyed hair. Regular shampoo can cause colored hair to fade quickly, so pick up a shampoo that's formulated to retain color, like R+Co Gemstone ($24, amazon.com) or Oribe Shampoo for Beautiful Color ($46, amazon.com).
