With all the hype about sunscreens lately, wouldn’t it be nice if someone came up with another way to protect your skin against sun damage without having to deal with sticky, pasty-white, sometimes ineffective, sunscreen?
Well it may happen soon. A recent study published in the Lasers in Surgery and Medicine found that pre-treating skin with light-emitting diodes (LEDs) protected the skin against ultraviolet light damage. LEDs, which are found in everything from Christmas lights to brake lights, produce low energy, harmless, cool light.
The researchers found that when people were given a series of LED treatments then exposed to ultraviolet light B (UVB is the more damaging radiation from sun exposure), the treated skin was less red and had less ultraviolet light damage as compared to untreated skin. They estimated that a series of LED treatments was equivalent to wearing an SPF 15 sunscreen!
More research has to be done to determine how effective LED light treatments are, especially on different skin types. Therefore, it’ll be sometime before LEDs will be considered a viable alternative to sunscreens. In the meantime, maybe you can hang your LED Christmas lights a little early this year and sit in front of them everyday. Can’t hurt.
