Light Emitting Diodes Can Smooth Wrinkles

LEDGerman scientists discovered that light emitting diodes can smooth out wrinkles and improve skin elasticity. The health benefits of visible light emission have been known for quite a long time. For instance, it was used to accelerate the wound-healing processes. But scientists couldn’t explain the effect until recently.

German scientists Andrei P. Sommer and Dan Zhu revealed that the exposure to intensive light on a daily basis for a few weeks results in more elastic and younger-looking skin, better complexion and reduced depth of wrinkles.

The scientists also explained the effect at a molecular level. Elastic fibers of skin are composed of elastin proteins that are able to hydrate – they become coated with a membrane of water. Hydrated elastic fibers then lose their flexibility, resulting in less elastic skin. It turned out that highly intensive light from diodes could penetrate through the skin and split off water membrane making the skin elastic again.

Researches believe their findings could become a base for new rejuvenating programs.
