Do Those Friday The 13th-Like LED Face Masks Work? A Doctor Explains
LED face masks have become a popular trend in the beauty industry, promising clinical-grade skin rejuvenation from the comfort of your own home. However, the evidence behind these glowing masks is more nuanced than the marketing suggests.
In November, the UK’s Advertising Standards Authority banned ads for at-home LED face masks from brands like Beautaholics, Luyors Retail, Project E Beauty, and Silk’n due to unauthorized medical claims in their advertising. These claims included promises to cure conditions like acne and rosacea, which are reserved for licensed medical devices under UK law.
The appeal of LED face masks lies in their visual impact, with glowing red panels reminiscent of a hockey mask strapped to the wearer’s face. Brands are racing to capture the growth in the market by touting claims of erasing wrinkles, eliminating acne, and reversing sun damage.
The technology behind LED face masks lies in photobiomodulation (PBM), where light energy is absorbed by receptors in mitochondria to trigger a cascade of effects that improve energy production, reduce inflammation, and stimulate collagen synthesis. Different wavelengths target specific skin concerns, such as collagen remodeling, inflammation, and bacteria-killing properties.
Research has shown that LED face masks can be effective for conditions like acne and skin rejuvenation. A systematic review and meta-analysis of 31 studies reported statistically significant benefits for acne and skin rejuvenation using red and blue LED protocols. Clinical trials have also shown improvements in skin elasticity and crow’s feet treatment with LED therapy.
However, there are legitimate caveats to consider when using at-home LED face masks. The devices studied in clinical trials may not be the same as the ones consumers purchase, leading to variations in efficacy. The quality of studies, sample sizes, and study durations can also impact the results. Additionally, the fit of the mask on the face can affect the delivery of light energy to the skin.
Dermatologists acknowledge that LED face masks can work but advise consumers to temper their expectations. Consistent use over several months may lead to measurable improvements in fine lines, skin texture, and mild inflammatory acne. It is essential to look for FDA-cleared devices with explicit wavelength specifications and adequate power output.
In conclusion, LED face masks can be a valuable addition to skincare routines when used correctly. Understanding the technology, regulatory status, and specifications of the device is crucial for achieving optimal results. Approach these devices with realistic expectations and consult a dermatologist for significant skin concerns.
