LED face masks have gained immense popularity in recent years, with many people turning to these high-tech devices in hopes of achieving younger, smoother skin. The masks, which can cost hundreds of dollars, use varying wavelengths of light to trigger reactions in skin cells. Red light is believed to boost collagen production, which can help improve skin texture and smooth fine lines and wrinkles.
Blue light, on the other hand, targets acne-causing bacteria on the skin’s surface. While there is some evidence suggesting that red-light therapy can improve the appearance of wrinkles, the data on blue-light therapy for acne remain inconclusive. “Some studies showed it helped, while others showed it didn’t, so the data isn’t robust,” said Dr.
Venkatesh, a dermatologist with Rush University Medical Group in Chicago. The efficacy of LED masks, especially those used at home, is still under scrutiny. The devices usually need to be used for four to six weeks to see any difference, and performance varies widely between devices, primarily due to the number of LED lights.
Higher-end devices typically have a higher concentration of LEDs, potentially leading to better results. However, higher efficacy also brings the risk of side effects such as blistering and pigmentation changes.
Efficacy of LED face masks
Despite the potential benefits, LED masks are not recommended for everyone. People taking light-sensitive medications or with conditions like lupus should avoid these devices. They are also not advised for young teenagers, who may not need such intensive skin treatments.
For most people, using an FDA-approved LED mask a few times a week poses no harm and might offer some benefits, depending on the intended use. Regular use is essential, with 10 to 15 minutes, three to five times a week being the recommended frequency. It is important to apply the mask on freshly cleansed skin and ensure it is clean before and after each use.
Masks with built-in eye protection are also recommended to safeguard vision over time. While the masks are generally safe, some dermatologists remain unconvinced of their value for money. “I think they look cool on TikTok,” said Dr.
Julia Carroll, a dermatologist and lecturer at the University of Toronto. “I don’t think for the amount of time you have to put in on these devices that you’re going to get a very dramatic result.”
As research evolves, the potential benefits of LED masks for various skin conditions, particularly for minimizing wrinkles, remain a topic of interest. However, taking the right precautions and picking the right device is crucial for those who want to incorporate these devices into their skincare routine.
