What Does an LED Mask Do to Your Skin?

What Does an LED Mask Do to Your Skin?

Each mask employs a different spectrum of light wavelengths that penetrate skin to trigger changes within skin at the molecular level, says Michele Farber, MD, a board-certified dermatologist with Schweiger Dermatology Group in New York City.

Each spectrum of light produces a different color to target various skin concerns.

For instance, red light is designed to increase circulation and stimulate collagen, making it useful for those who are looking to reduce the appearance of lines and wrinkles, she explains. A loss of collagen, which tends to happen in aging and sun-damaged skin, can contribute to fine lines and wrinkles, past research in The American Journal of Pathology shows.

On the other hand, blue light targets bacteria that cause acne, which can help stop the cycle of breakouts, notes research in the Journal of the American Academy of Dermatology in June 2017. Those are the two most common and popular colors used, but other masks on the market use additional lights, such as yellow (to reduce redness) and green (to lessen pigmentation).
