So Many LED Face Masks Are on Sale for Prime Day—Beauty Editors Say This One Actually Works
Beth Gillette · 2026-06-25 · via Latest Content - Cosmopolitan

One thing about the Cosmo beauty team? We’re all in on LED masks. Over the years, we’ve tried them all—from the inexpensive Amazon finds to the $700+ devices that your favorite celebrities and their aestheticians swear by. That said, there are only a handful that remain regulars in our skincare lineup rotation, one of them being Dr. Dennis Gross SpectraLite FaceWare Pro. Dr. Dennis Gross LED mask was one of the first ones to bring LED out of the derm offices and spas and hit the mainstream, aka the shelves of Sephora, and kick off the at-home mask movement back in 2018.

Below, we compare Dr. Dennis Gross’s LED mask to others on the market and give it our most thorough and honest review. Keep scrolling for everything you need to know about the Dr. Dennis Gross SpectraLite FaceWare Pro, according to years of editor testing. And if you’re entirely new to the LED game, do yourself a favor and check out this guide to red light therapy here. And if you’re new to the LED game, check out this guide to red light therapy, written by our editors.

About the Dr. Dennis Gross Skincare LED Mask:

SpectraLite™ FaceWare Pro LED Device

Usage: Three minutes, daily

Price: $455

Settings: Red, blue, and purple light

Who it’s for: Anyone looking to help potentially reduce fine lines and wrinkles, bring down inflammation, and minimize breakouts

Does Dr. Dennis Gross LED mask really work?

TL;DR: The Dr. Dennis Gross LED mask will *potentially* work. While there's no hard evidence for it, many experts believe that red LED (aka light-emitting diode) "act on fibroblast cells in your skin, which play a role in collagen production," says dermatologist Hadley King, MD. "So, in theory, red light could help to reverse some signs related to photoaging in the skin—like fine lines, wrinkles, sagging skin, and dullness—but in reality, we don't yet have enough scientific evidence to prove effectiveness."

Blue light, however, is often recommended for acne, since it can potentially reduce activity in your sebaceous glands, as well as kill some acne-causing bacteria. The Dr. Dennis Gross mask, FYI, offers red, blue, and purple light, which combines them both—to avoid wrinkles and breakouts.

And if you're comparing LED masks to in-office laser treatments (or at-home lasers, like the Nira Laser), don't expect nearly the same level of results, but the main takeaway is that consistency is key when it comes to the skin-improving abilities.

How often should you use the Dr. Dennis Gross LED mask?

You should use this LED mask for three minutes a day, at least three or four times a week, to see results, says Dr. King. I personally sit with my Dr. Dennis Gross LED mask about four to five times a week. It's super easy to incorporate into my routine—I wear it while making my morning coffee, and by the time my barista duties are complete, time is up on my session.

Cosmo Beauty Editor Reviews:

Beth Gillette, beauty editor

My skin is extremely acne-prone and fairly oily, sometimes leaning towards combination in the depths of winter on my cheeks and neck. In general, though, I have pretty tough skin that doesn't get irritated easily, but breaks out from nearly every pore-clogging ingredient out there. My goal with the Dr. Dennis Gross LED mask was to help bring down some of the inflammation from my zits, especially hormonal acne on my chin, as well as encourage collagen production to keep my skin tight and firm as I'm heading into my late 20s. And smoothing out my uneven skin texture wouldn't hurt, either.

Four to five days a week, in the morning, I pop on my Dr. Dennis Gross LED mask on clean skin while I sip my iced coffee (through a straw, FYI!). Truly, it's that simple. A few times, I would use it at night while watching TV, but I prefer using it in the morning so that I don't have to split my longer nighttime skincare routine into a bunch of steps (since you should use it on clean skin, per Dr. King, versus a face covered in serums and creams).

Compared to other LED masks I've tried (like the OmniLux, CurrentBody, and SolaWave), I actually prefer that this isn't a silicone-based mask that conforms to my face. I find it more comfortable and easy to wear, especially for puttering around my house with it on. All I gotta do is press the button to turn it on, and live my life. Plus, one session is only three minutes, compared to the 10 to 15 minutes other devices require.

Side-by-side before and after comparison of skincare results.

I'll be honest—I didn't notice that much of a difference in my skin until I saw these images side-by-side. But now, I totally can tell that my skin is less inflamed. Do I still have hormonal breakouts? Yup. But they're not nearly as red and monstrous as my normal cystic acne gets. And because of this, I've noticed my zits go away a little bit quicker. Overall, I also notice my face looks a bit less puffy—likely because my inflammation is reduced.

Jasmine Hyman, assistant beauty editor

My skin is dry, acne-prone, and sensitive, so my skincare routine is quite simple these days. But an LED device is a constant in it. I’ve tried so many masks over the years, and Dr. Dennis Gross’s is in my top two. I’m also a fan of Shark’s CryoGlow Mask for its handy remote to keep track of your session history, as well as the cooling under-eye design, but I prefer storing the Dr. Dennis Gross Mask in my small NYC apartment since it doesn’t take up as much space. It’s easy to store in a drawer or under my bed, and it’s a nice middle ground between a face-hugging silicone style and a big, bulky helmet.

Now, onto the actual treatment itself. I love that the sessions are only three minutes, which makes me more motivated to do it every single day, instead of needing to carve out 10 minutes like other tools. There’s also no wire or remote needed, which makes it a super hands-free experience. As an acne-prone gal entering the latter half of her twenties, the purple light setting (a combination of blue and red light) is perfect for my two major skin concerns—breakouts and anti-aging.

And in a world where not all LED masks are created equally (those under-$100 devices on Amazon are likely the equivalent of holding Christmas lights on your face), Dr. Dennis Gross’s mask has 162 light sources (which is pretty standard), and while $455 is quite a splurge, the quality and fit of this mask is better than most that I’ve tried—it’s comfortable to wear, sitting just above the skin, without being too bulky.

Whenever I use LED masks, my skin is always less reactive, and my breakouts are (for the most part) reduced, and that remains the case after months of testing this one. As far as anti-aging benefits go, I don't notice an improvement there (granted, I'm not completely concerned with wrinkles and fine lines just yet). However, I’m using it more as a preventative measure in order to slow signs of aging, rather than an attempt to reverse them.

The pros and cons of the Dr. Dennis Gross Mask:

Pros:

  • Hard yet flexible material makes it easy to store
  • Session lengths are only three minutes
  • Three different treatment options
  • Battery life lasts a while

Cons:

  • On the pricey side
  • 162 light sources are pretty standard

Is the Dr. Dennis Gross mask worth it?

The Dr. Dennis Gross mask might be worth it for you, depending on your budget, goals, skin type, preferences, and more. We personally love how this device feels on our faces and seamlessly fits into our existing skincare routines. It also fully covers the face and feels so comfortable to wear—not to mention that you only have to keep it on for three minutes. Compared to other devices we’ve tried, we’ve gotten the best results from this one...but that could be because we love the feel and length of treatment so much that it’s easiest to stay consistent.

But let’s bring up the elephant in the room here: This mask is expensive, coming in at $455 before any discounts (this always goes on sale during the Sephora sale, as well as Amazon Prime Day, FYI). There are cheaper LED masks on the market, like SolaWave and Shark, that might fit into your budget a bit easier.

Again, remember there aren't large-scale studies demonstrating that these masks are totally effective just yet. Anecdotally, though, many aestheticians and experts do swear by them (and team Cosmo’s before and afters make us believers too,). So if you've got the cash and want to commit to an LED mask, you can’t go wrong with Dr. Dennis Gross’s.

Final verdict:

In our beauty editors’ opinion, Dr. Dennis Gross’s SpectraLite FaceWare Pro is worth it if you’re willing to splurge on an LED mask. While our results speak for themselves, it’s important to stay consistent with the device if you want to see any meaningful results. Overall, if you’ve been wanting to get into the world of LED, Dr. Dennis Gross’s is a great option for a comfortable and quick session.
