Cons: Powerful mask which needs to be plugged into a wall socket, so you'll have to stay put during sessions
How we chose the best LED face masks
As the trend for red light therapy and LED treatments continues, there are a slew of buzzy new devices being released. But choosing well is key: not all LED face masks are created equal. It can be hard to know what to look for in a good LED device, which is why we’ve consulted experts from the best clinics in the business to discover the wavelengths that actually work (according to The Light Salon co-founder Hannah Measures, that’s 630nm for red light and 830nm for near infrared) shortlisted the masks that are worth your money, and tried them on for size. Each device in our edit has been put to the test by our editors for at least one full skin cycle, so we can properly report on how well they work to improve the complexion, and we’ve taken into account comfort, convenience and ease of use.
FAQs
What is LED light therapy and how does it work?
LED (or light-emitting diode) therapy is a treatment that exposes the skin to different wavelengths of light. “This light is absorbed by the mitochondria – the powerhouse of our cells – which can trigger a variety of biological responses,” says Bradden. Among them: enhanced circulation, increased collagen production and tissue repair – all of which result in brighter, plumper and smoother skin.
And the benefits aren’t just skin deep. “The absorbed light energy can stimulate the release of growth factors, neurotransmitters and also reduce inflammation,” Bradden continues, explaining that this is why LED exposure can have positive benefits in areas as varied as pain reduction, brain function, and hair growth.
What colour LED do I need?
Different LED colours have different wavelengths which penetrate the skin at varying depths. To target specific skin concerns, Dr Yoo stresses the importance of choosing the right LED wavelength for the issue you want to treat. See her recommendations in the table below:
| LED colour | Clinically effective wavelength | What it does |
|---|---|---|
| Red | 630-700nm | Red LED light stimulates collagen production, reduces inflammation and enhances blood circulation. It effectively targets fine lines, wrinkles, inflammation, and aids in wound healing. Clinically proven wavelengths for red LED therapy range between 630-700nm, penetrating deeper into the skin for overall rejuvenation and stimulating cellular repair which results in relief from discomfort and improved joint mobility too. |
| Near Infrared | 700-850nm | Near Infrared LED light penetrates even deeper into the skin and tissues, reaching muscles, joints (and even organs, according to Bradden) while aiding wound healing, reducing inflammation, and providing pain relief. |
| Blue | 405-420nm | Blue LED light is renowned for its ability to combat acne-causing bacteria and regulate sebaceous gland oil production. LED Face masks that have blue light wavelengths within the clinically proven range of 405-420nm will effectively reducing acne lesions and prevent future breakouts. |
| Yellow | 570-590mm | Yellow LED light, though less commonly used than red and blue, helps in reducing redness and healing time. It complements red LED therapy in fading fine lines and promoting lymphatic drainage. Clinically proven wavelengths for yellow LED therapy range between 570-590nm and are particularly beneficial for sensitive skin. |
| Green | 525-550 nm | Green LED light has a significant collagen-boosting effect and improves skin tone and texture. Administered at wavelengths around 525-550nm, it reduces pigmentation and brightens the skin. |
| Purple | 400nm | Purple LED therapy (a combination of red and blue light) aids in toxin elimination, reduces inflammation and enhances healing and blood circulation. Best used after aesthetic treatments, it aids wound healing while diminishing acne, and reduces visible acne and acne marks. Clinically, it’s recommended at around 400 nanometres. |

Are LED masks good for your skin? What are the benefits?
Yes. Depending on the light emitted by the mask, they can offer a multitude of benefits. For example, while red light increases collagen and elastin production, blue light targets acne-causing bacteria, green light helps with pigmentation, and yellow is brilliant for healing. When combined with a good daily skincare routine, they can help improve skin health from the inside out, boost radiance, tackle acne and other skin conditions, and leave the skin clearer, smoother and plumper.
