In the world of high-tech beauty gadgets, LED (light-emitting diode) masks have become a regular - and more easily accessible - part of at-home skin-care routines. Gone are the days when the red light therapy devices were seen as pricey futuristic treatments - some of the best at-home LED face masks and devices are proven to reduce the appearance of wrinkles, fine lines and scars; soothe rosacea; and treat inflammation. "LED light therapy is a non-invasive treatment that uses specific wavelengths of light to penetrate the skin at varying depths, triggering natural biological responses," board-certified internal medicine and aesthetic physician Dr. Glenicia Nosworthy tells The Hollywood Reporter. Light wavelengths are measured in nanometers (nm), each delivering "unique benefits, so choosing the right one for your skin concerns is essential," she adds.

Near-infrared or NIR (700-1200nm): "Penetrates even deeper than red light to target muscles and joints." Blue light (400-490nm): "Targets the surface layer of the skin, killing acne-causing bacteria." Green light (495-570nm): "Affects skin pigmentation by calming overactive melanocytes." The founder of Glo by Glen Skincare, Nosworthy is known for pioneering "beauty hacking," her approach of combining science-backed techniques, lifestyle adjustments and innovative tech to "optimize beauty from the inside out," she says. At her Brooklyn medispa, Nosworthy offers her starry (and HIPAA-confidential) clientele dermal fillers, microneedling, platelet-rich fibrin (PRF) injections and more skin enhancements. Also on the menu is the celebrity-loved, red carpet-ready Glass Facial, a rejuvenating treatment that uses her collagen-stimulating topical polydioxanone (PDO) serum, hyaluronic acid and a microdose of Botox. LED light therapy was initially developed by NASA scientists in the early '90s, first for plant growth experiments in space and thereafter to boost the wound healing of astronauts. The light's wavelengths can go deep into body tissue to promote blood circulation and collagen production, which is why the skin-care industry jumped on the high-tech train to bring LED light therapy to top Hollywood spas. "The use of light on skin is not a new technology, but as LEDs have improved and become more efficient, so have LED-based technologies," Mike Poling, president of Lightwave, and a 16-year innovator in the field, previously told THR. He explains that the usage of LED lights on the skin helps to re-energize cells: "This increase in energy helps our cells function more like they did when we were younger with the immediate effects being a release of endorphins, a reduction in inflammation, and an increase in lymphatic system activity to help detoxify the body." Among the most popular LED face masks is the Dr. Dennis Gross DRx SpectraLite FaceWare Pro, which went viral when it launched in 2020 after stars including Kris Jenner, Kim Kardashian, Lucy Hale and Halle Berry shared their quarantine selfies wearing the device. Since its debut, other red light therapy devices have landed on the market with even more features, such as cryotherapy, vibration therapy and more. What Are the Best LED Masks and Skin-Care Devices?
