The most proven of these LEDs is red and infrared light, which support your skin’s natural collagen and elastin-producing efforts like a high-tech cheerleader.

Need further proof? A study observed imporvement in wrinkles and fine lines following the use of 633, 830, and 1072 nm combination masks, while another 2021 study found there to be an improvement in atopic eczema (also known as atopic dermatitis, a chronic inflammatory skin condition) in both men and women after twelve weeks of treatment. Another National Library of Medicine study found that skin elasticity can be significantly improved after eight weeks of consistent use.

Of course, no at-home LED device is going to be as powerful as a professional treatment. But using an LED mask regularly has cumulative effects, notes Dr Granite: “LED masks are generally safe to use everyday; in fact consistency yields the best results. Some recommend use for as little as five minutes a day, others require up to 20 minutes.”

It all depends on the skin conditions you’re trying to target and, of course, your skin type.

There are numerous light colours most readily used in at-home LED masks, from red LED to blue – and each have different benefits. Here Dr Granite breaks down the benefits of each coloured light:

My experience of LED treatments:

For me, at least, the most satisfying part of any facial is the moment a pair of goggle-like protectors are placed over my eyes and I feel the relaxing warmth from the LED device hovering above my face. So yes, using an LED mask at home is going the extra mile but as I’ve discovered, it’s worth it.

I tried various different wireless masks over the two months, all of which have pros and cons.

The best is the CurrentBody LED Face Mask Series 2, which we’ve written a full review of elsewhere on site. Every bulb in this mask emits the exact wavelengths of light proven for results (red (633nm), near-infrared (830nm) and deep near-infrared (1072nm)), and I found the mask to cover the entirety of my face. The lights reach crows feet and your chin, which can’t be said for all models. You can also use the VERITACE® NFC card which comes in your mask’s box to view each stage of quality testing that your exact mask has passed, providing proof of its efficacy.

The next was The Light Salon Boost LED Mask, a good entry-level device and a best-seller at Selfridges. The only trouble is, because I have quite sensitive eyes, I found the light too bright and had to lie down with them shut for 10 minutes every time I strapped myself into the mask – something that required too much effort when all I really wanted to do was watch another episode of Hijack.

There was the Dennis Gross DRX Spectralite Eyecare Max Pro, too, which looks like light-emitting VR goggles. Pre-programmed for just three minutes, it was simple to use and I found it incredibly soothing after a day staring at a computer screen. But I couldn’t quieten the niggling voice telling me that the rest of my face was missing out.
