Infrared Light Therapy for Your Face: What It Is and How to Do It at Home

Red and near-infrared light therapy has moved from clinic treatment rooms into at-home devices sold at a fraction of the clinic price. Here is what the technology actually is, what the evidence says, and how to fit it into an evening routine without a clinic appointment.

What is infrared light therapy?

Infrared light therapy — sometimes called photobiomodulation or red light therapy — uses low-level red and near-infrared wavelengths of light directed at the skin. It is not UV light, it does not tan or burn, and it does not involve heat at the levels used in at-home devices.

The two wavelengths that appear most frequently in the evidence base are red light (typically in the 630–700 nm range) and near-infrared light (typically 800–900 nm). Both are used in the leading at-home devices and in clinic treatments. Devices sold for home use, including full-face LED masks, use the same wavelength categories as clinic equipment — the difference is in the session format and the price point, not the underlying technology.

What does the evidence say?

The honest position is this: there is a reasonable body of research on red and near-infrared light therapy for skin health, and it is promising, but the study quality varies and the effect sizes are not always large. The mechanism — light interacting with skin cell mitochondria to support natural repair processes — is well documented at the cellular level. The clinical evidence for visible skin improvements with consistent use is meaningful enough that premium clinic facials and high-end at-home devices in the £300–400+ price range have built entire product categories around it.

What the evidence does not support is a guaranteed result on a specific timeline. Light therapy is a consistency habit. The people who see the most from it are the ones who do it regularly — 10–15 minutes, most evenings, over 30 nights — rather than the ones who try it twice and judge it against a before-and-after claim.

What at-home devices actually do

A full-face LED mask delivers red and near-infrared light across the whole face in a single session, hands-free, without a clinic appointment. Premium devices — like those retailing at £300+ — use high-density LED arrays to cover the face evenly. At-home devices in the £100–200 range now use the same wavelength categories, making this technology more accessible than it was even three years ago.

The format matters. Full-face coverage is more efficient than a handheld wand you move across zones. Cordless, rechargeable devices are easier to fit into a routine. And 10–15 minutes as an evening step, rather than a separate appointment, is what most people can actually sustain.

How to do infrared light therapy at home

1. Start on a clean, dry face. No serum, oil or SPF underneath the mask — a clean surface is the correct starting point and maximises the contact between the light and the skin.
2. Wear it for 10–15 minutes. Set a timer, put it on, and let it run. Most people do this sitting or lying down at the end of the day. Cordless devices mean nothing trailing to a socket.
3. Follow with your usual skincare. Night serum or moisturiser goes on after the session, not before.
4. Repeat most evenings for 30 nights. This is the format the evidence base is built around. Judge it against a photograph taken in the same light on night one.

Who should not use infrared light therapy

At-home infrared devices are not medical devices and are not designed to treat diagnosed skin conditions. Anyone who is pregnant, has a skin condition affecting the face, or takes medication that increases sensitivity to light should speak to a GP or pharmacist before starting. Keep eyes closed during a session and do not look directly into the LEDs. Do not use on broken or irritated skin.
