According to German researchers, tiny high-intensity lights might reduce wrinkles and lead to younger-looking skin without the need for cosmetic surgery or Botox. This research is basically on elastin which is the main factor behind skin elasticity. Andrei P. Sommer and Dan Zhu from the University of Ulm in Germany are behind this research. The study is published in the Nov. 5, 2008, issue of the American Chemical Society journal Crystal Growth & Design.

Highlights of the study
a. Researchers discovered that during aging, water layers surrounding elastin fibers change and affect the elastin fibers.
b. This, they say, may be behind the formation of wrinkles.
c. It was assumed that high-intensity visible light from LEDs may be used to change the molecular structure of the water layer to free up elastin.
d. An array of LEDs that gave off 600-720 nanometers of light was used in this study.
e. To prevent adverse effects to the cells from the light penetrating the skin, the doses were adjusted to temporarily increase circulation.
f. It was seen that after 9 weeks of daily treatment, the wrinkles of participants reduced noticeably.
g. It also led to rejuvenated, younger-looking and more resilient skin.
h. It was concluded that LEDs can easily be converted to deep-body rejuvenation programs.
