LED & Red Light Masks

LED and red light masks, compared on wavelength and clearance

Six brands dominate this category and four of them publish almost nothing you can check. Here is what each one actually emits, which clearance numbers exist, and which specification is missing from every single spec sheet.

An LED face mask is a grid of diodes held against your skin for a fixed number of minutes. That is the whole device. Everything that separates a $150 mask from a $470 one comes down to four numbers, and the industry has quietly agreed to publish only two of them.

Start here

The four numbers that decide this category

  1. Wavelength, in nanometers. 633 nm red and 830 nm near-infrared are the two with the deepest published literature. 415 nm blue is the acne wavelength. 1072 nm is the deep near-infrared that CurrentBody built its upgrade story on. Green at 532 nm and yellow at 590 nm appear on the newest masks with a much thinner evidence base behind them.
  2. Diode count. Useful only as a proxy for coverage. A mask with 750 diodes spread over the same surface area as one with 132 is not delivering six times the dose; it is delivering light from more, smaller sources.
  3. Irradiance, in milliwatts per square centimeter. This is the one that actually governs dose, and it is the one almost nobody publishes. Omnilux publishes roughly 30 mW/cm2 across its Contour line. CurrentBody, Therabody, Shark and Dr. Dennis Gross publish nothing. We explain why that matters here.
  4. Session length and frequency. Three minutes on the Dr. Dennis Gross, ten on the CurrentBody masks. Dose is irradiance multiplied by time, so a three-minute session at an unpublished irradiance is a genuinely unanswerable question.

Put those together and the honest conclusion is uncomfortable: for most masks in this category, nobody outside the manufacturer can calculate the dose being delivered. Not us, not the magazines, not the dermatologist quoted in the magazine. What we can do is tell you exactly which figure is missing from which spec sheet, which is more than anyone else in this search result does.

Regulation

What FDA clearance does and does not tell you

Every brand in this category writes "FDA cleared" on the box. Very few of them will tell you the clearance number, and when you go looking in the FDA's own free, public 510(k) database, the results are not what the marketing implies.

We searched it, device by device. The CurrentBody Series 2 has a clean, current record: K250966, cleared 25 June 2025. The Shark CryoGlow has K242796, cleared 27 November 2024, and its indications explicitly cover inflammatory acne as well as wrinkles. The Therabody TheraFace Mask has K230293. Those three we can point you to.

The Omnilux Contour Face, the single most recommended mask in this category, returns no record under that device name. The brand's wrinkle-reduction clearance on file is K072459, from March 2008, for a device called Omnilux New-U. The Dr. Dennis Gross FaceWare Pro returns no record under the brand, the device name, or SpectraLite. That does not prove no clearance exists, and it does not mean either device is unsafe. It means the claim on the box is one you cannot verify, and the difference between cleared and approved matters more than the marketing suggests.

Fit

Flexible or rigid, and why it changes the result

A rigid shell sits away from the cheekbones and the sides of the nose. A flexible silicone mask lies flat against them. Since irradiance falls off with distance, a mask that stands five millimeters off your skin is delivering less light there than the spec sheet implies, and the spec sheet already did not tell you the irradiance. Silicone masks, as a group, solve a problem that rigid masks have and do not advertise.

The trade-off is real though. Rigid masks are easier to clean, hold their shape in a drawer, and tend to be cheaper for the same diode count. If you have a narrow face or a prominent nose bridge, try to see one on a face before committing.

The short version

Who each mask is actually for

  • You want the cleanest verifiable story: the CurrentBody Series 2. It is the one device here with a current, locatable clearance for the exact model and three wavelengths.
  • You want the highest published irradiance: the Omnilux Contour Face. It is the only mainstream mask that publishes the figure at all, and ~30 mW/cm2 is a real number you can reason about.
  • Your main problem is acne, not lines: the Shark CryoGlow, whose clearance names inflammatory acne, or the Omnilux Clear, whose acne clearance (K210948) we also located.
  • You will not stick to a ten-minute session: the Dr. Dennis Gross FaceWare Pro, at three minutes. The best mask is the one you actually use.
  • You want everything and will pay for it: the CurrentBody Series 3, with six wavelengths and 750 diodes. Understand that you are buying coverage, not a proven dose.

Do LED face masks actually work?

An honest assessment: a real mechanism, decent clinic evidence, and a home-device literature thinner than the marketing suggests.

FAQ

LED & Red Light Masks: common questions

Do LED face masks actually work?
Red and near-infrared photobiomodulation has a genuine clinical literature behind it, mostly from professional-strength devices. The open question for home masks is dose: whether a consumer device at an unpublished irradiance, used for the stated session length, delivers enough energy to matter. We work through the evidence here.
Which LED mask has the highest irradiance?
Of the masks that publish a figure at all, the Omnilux Contour line states roughly 30 mW/cm2 and the Omnilux Clear states 44 mW/cm2. CurrentBody, Therabody, Shark and Dr. Dennis Gross do not publish irradiance for their masks, so a ranking across the whole category is not possible with the data that exists.
Is a mask with more LEDs better?
Not on its own. Diode count tells you about coverage and uniformity, not about the energy arriving at your skin. A 750-diode mask with no published irradiance is a less answerable question than a 132-diode mask that states 30 mW/cm2.
Can I use an LED mask every day?
Manufacturers in this category typically specify three to five sessions a week rather than daily, for an initial four to six weeks, then maintenance. Our frequency guide covers what the protocols actually say.
