Face Slimming Masks: Do They Really Create the Ideal Face Shape?

A good percentage of the beauty trends we see that come out of Korea are effective. Most are, at the very least, quite intriguing. So whenever we hear of a new fad taking Seoul by storm, needless to say, we're going to do everything we can to try it. And that, folks, is how face slimming masks, also known as V-masks, made their way to the Byrdie offices. Like undereye patches for your chin, these sheets promise a sharper, firmer jawline, no surgery needed. 

But do they actually get the job done? Keep reading to learn all about face-slimming masks and if they really work to tighten the jawline, according to experts.

What Are Face Slimming Masks?

Face slimming masks are basically a hybrid between a sheet mask, an undereye patch, and a chin strap. Their goal is to help shape the chin area while lifting and defining the lower part of the face. They are meant to improve facial contouring and tighten the face without surgery. 

"With gravity over time and loss of collagen and elastin for structure, we start to see a sagging or loose jawline," explains Shamban. "A shaped jawline is not only desirable for Korean women, but for all women of a certain age," adds Franz.

How to Apply Face Slimming Masks

The mask has holes at each end, which you loop around your ears to hold it in place. The fabric is often infused with firming ingredients, such as collagen, vitamin C, vitamin E, macadamia nut oil, and caffeine. 

But the application process itself is also definitely a factor: Like waist-training for your jawline, it sucks the skin in to help stimulate blood flow. "The only real rule of thumb is to apply to a clean, dry face with clean hands. No product should be applied to the skin prior to application," says Shamban. Comfortable and quick, most of the masks take 20 to 30 minutes to work on your face.

It really feels like Spanx for your chin—it's that tight. But while it tingled a bit, it wasn't at all painful or uncomfortable. And because your ears keep it in place, you don't have to lie down or stay immobile, which we consider a win-win in our books. Depending on your needs, it can be worn once a day, every day (e.g., at bedtime, when you wake up in the morning, or even while you're doing your makeup).

Do Face Slimming Masks Really Work?

In a way, yes. Much like your skin is bound to feel more hydrated and replenished after using a mask, we definitely notice some immediate firmness and smoothness along the jawline whenever we use a V-mask. 

Shamban says the results are temporary, like a good night's sleep or a little caffeine jolt for the lower portion of your face. "They are an intensified delivery system for actives that will temporarily lift, tighten, and improve one's profile," she says. 

"Although they don’t always have dramatic results, they may subtly address skin concerns in the area around the lower face, jawline, and neck, which are oftentimes neglected in most skincare regimens," notes Nazarian. Ultimately, expectations need to be set appropriately when using a face slimming mask. 

How Long Do Results Last?

As we know, these effects are neither drastic nor permanent—just a much-appreciated, quick pick-me-up. "For clinically apparent changes, you may see a temporary improvement. Long-term changes are more subtle," says Nazarian. So basically, it has an immediate effect for several hours at a time for most (it might be longer for some).

The Takeaway

As with most nonsurgical beauty methods, maintenance is key. The improvements from the slimming masks, such as from “slimming” ingredients like caffeine, are only temporary and last about a day. "The ideal way to contour the lower face is really with a more permanent solution, such as lasers and radiofrequency," says Nazarian. In order to really enhance and maintain results, she indicates the masks should be used regularly and long-term.
