An infrared face mask is almost always an LED face mask that includes near-infrared light, usually around 810-850nm, alongside visible red. The near-infrared part is invisible and travels deeper into skin than red light. The research mostly looks at red and near-infrared used together, and results are modest and gradual rather than dramatic. Here is what that means in practice, and what to check before you buy one.

What is an infrared face mask, really?

Search for "infrared face mask" and you will find masks that look identical to any other LED mask. The label is shorthand. It points to the near-infrared (NIR) LEDs inside, the ones you cannot see.

So when a brand says "infrared", read it as "this mask includes near-infrared LEDs". The useful question is what wavelengths, how many, and whether they run on their own or only blended with red.

The three things people mean by "infrared"

The word covers very different technology. This is where most of the confusion comes from.

Type	Typical wavelength	Where you find it	How it works
Near-infrared LED	810-850nm	Most LED face masks and panels	Low-level light absorbed in skin and tissue. Little heat.
"Deep" near-infrared	Around 1072nm	A few premium masks	Longer wavelength, limited published research for home devices.
Far-infrared heat	Several thousand nm	Infrared saunas, heat pads	Warms tissue. A different mechanism entirely.

An infrared sauna and an infrared LED mask are not the same thing. One heats you. The other delivers low-level light. If you are weighing the two, our guide to red light therapy vs infrared saunas covers the difference.

Red light vs near-infrared in a mask

The practical difference is depth. Red light (around 630-660nm) is absorbed mostly in the upper layers of skin. Near-infrared (around 810-850nm) reaches further, into deeper skin and the tissue beneath. A 2026 review of what to look for in red light devices, published in PubMed Central, describes the same split (read the review).

The honest limit for anyone shopping for an "infrared" mask: most skin trials used red and near-infrared together, on clinic equipment, so they cannot tell you what near-infrared does on its own or guarantee a home device will match. The Mayo Clinic Press puts it plainly: subtle improvements in texture and wrinkles are reported, but at-home versions have been less effective than clinic treatments, and long-term studies are lacking (source).

We cover the studies and every mask colour in LED Face Mask Colours Explained, and 810nm vs 850nm in Understanding Wavelengths.

Why you can't see an infrared mask working

Near-infrared is invisible. You may notice a faint red glow around the edge of the LEDs, which is normal, and a very gentle warmth on the skin. Neither tells you how well the mask is performing.

This catches people out. If the mask looks dim, it does not mean the NIR is weak. If it looks bright, it does not mean the NIR is strong. The only reliable way to judge is the spec sheet: the stated wavelength, the number of LEDs on that wavelength and, ideally, a published output figure. Our dosage guide explains why irradiance matters more than how bright the mask appears.

Are infrared face masks safe?

For most healthy adults, near-infrared LED masks have a low-risk profile when used as directed. The American Academy of Dermatology says red light therapy appears safe in the short term and that research has not found it causes cancer, unlike ultraviolet light (AAD guidance). It also notes that results take regular use and not everyone sees them.

Practical points worth knowing:

• Gentle warmth is normal. Near-infrared can feel faintly warm. Hot or uncomfortable is not normal, so stop and check the device.
• Don't stare into the LEDs. This applies to every LED device at close range, because you cannot see the infrared part. Close your eyes or use a mask with a clear visor, and follow the user guide. See our full guide on LED face masks and eye safety.
• Check first if any of these apply: you are pregnant, you take light-sensitising medication, or you have a medical condition affecting your skin or eyes. Speak to a healthcare professional. Our safety and contraindications guide lists who should be cautious.
• Keep sessions to the recommended time. More is not better. Most masks suggest 10-20 minutes a few times a week.

You do not need goggles with the Lumovex Spectrum Pro. It has an open visor, so you can see while wearing it. The habit is simple: don't stare into the LEDs.

What to check before you buy an infrared face mask

Marketing around "infrared" is loose. Use this checklist and you will filter out most of the noise.

1. Is the near-infrared wavelength stated? You want a number (810nm, 850nm), not "infrared technology".
2. Is it a separate mode or only blended? A dedicated NIR mode lets you choose it. A blended-only mask decides for you.
3. How many LEDs, and on which wavelengths? Total LED count means little if most are on one wavelength.
4. Is output published? Look for irradiance in mW/cm2 or a measured figure. If the brand will not say, treat that as information.
5. Is it CE certified? It should be a CE certified wellness device. Be wary of "medical grade" claims, which have no legal definition in the UK. Our guide to "medical grade" red light therapy explains why.
6. What are the returns and warranty? Thirty days to return and a two-year warranty are a sensible baseline.
7. Is it sold by a UK seller? UK stock, UK support and no customs fees matter if something goes wrong.

Where the Lumovex Spectrum Pro fits

The Lumovex Spectrum Pro LED face mask has 328 LEDs across four wavelengths: green 525nm, amber 590nm, red 660nm and near-infrared 850nm. Each of its four modes uses one wavelength. Deep Repair is the near-infrared mode, so 850nm runs on its own when you choose it, rather than being blended in without your say.

• Full-face coverage with a clear visor across the eyes
• Rechargeable by USB-C, so no plug socket during a session
• 10-15 minute sessions with auto-shutoff, 3-5 times a week
• CE certified wellness device
• £149.99, with 30-day returns, a 2-year warranty and UK-based support

It is worth saying what a mask like this is and is not. It is a gradual, at-home skincare routine, not a clinic treatment and not a substitute for medical advice. Many people look for changes in how their skin looks and feels over several weeks of consistent use, and results vary.

Infrared face mask FAQ

Do infrared face masks work?

Research on red and near-infrared LED light points to modest improvements in skin texture and the look of fine lines with regular use. Most studies combined both wavelengths and used clinical equipment, so home results are gradual and vary person to person.

Are infrared face masks safe?

They have a low-risk profile for most healthy adults when used as directed. Don't stare into the LEDs, keep to the recommended session time, and check with a healthcare professional first if you are pregnant or take light-sensitising medication.

Can you see infrared light from a face mask?

No. Near-infrared is invisible. You may see a faint glow at the edge of the LEDs and feel mild warmth. Judge a mask by its spec sheet, not by how bright it looks.

Is an infrared face mask the same as an infrared sauna?

No. An infrared LED mask delivers low-level near-infrared light with little heat. An infrared sauna uses far-infrared heat to warm the body. They work in different ways.

How often should you use an infrared face mask?

Most masks suggest 10-20 minutes, three to five times a week. Consistency matters more than longer sessions. Follow your device's user guide.
