LED, Green Tea Combo Shown Effective Against Wrinkles
Posted: September 15, 2009
German researchers have shown that using LED technology in combination with a green tea extract lotion can have a visible effect on facial wrinkles and fine lines.
Scientists in Germany are reporting a major improvement in their potential new treatment for facial wrinkles that could emerge as an alternative to Botox and cosmetic surgery.
The noninvasive technique combines high-intensity light from light-emitting diodes (LEDs) and a lotion made of green tea extract. It works 10 times faster than a similar anti-wrinkle treatment that uses LEDs alone, the researchers say.
Andrei P. Sommer and Dan Zhu point out that researchers have used light therapy, or phototherapy, for more than 40 years to help heal wounds. Recently the scientists showed that use of high-intensity LEDs, similar to those used in automotive tail lights and computers, could help reduce skin wrinkles when applied daily for several months.
But exposure to intense LED light is also involved in generating high levels of reactive oxygen species as by-products that can potentially damage cells. To combat that effect, the researchers combined the LED with a potent antioxidant in green tea extract called epigallocatechin gallate.
