LED light and green tea - a new miracle cure for wrinkles?New combination works 10 times faster than LED lights alone
German scientists have been using high powered LED light to help heal wounds for over 10 years.
Now they have created a new therapy that can reduce the appearance of wrinkles to what they describe as a "juvenile complexion".
Previously the scientists had shown that high-intensity LEDs, similar to those used in car headlamps and computers, could help reduce skin wrinkles when applied daily for several months. But this was no miracle cure as the intensity of the light beam generates high levels of reactive oxygen that can potentially damage cells.
To combat this effect, they applied a lotion containing an extract from green tea. The extract, called epigallocatechin gallate, has powerful anti-oxidant properties.
They applied a daily combination of LED light and green tea extract to the facial wrinkles of a human volunteer for one month. The combination treatment resulted in smoother skin, including "less pronounced wrinkle levels, shorter wrinkle valleys, and juvenile complexion," the scientists say.
The treatment showed promising results in only one-tenth of the time it took for LED therapy alone to reduce wrinkles. The study could form the basis of "an effective facial rejuvenation program," and lead to a new understanding of the effect reactive oxygen species on cellular aging, they note.
The results are shown in the image, which shows the effects of the LED treatment alone on the left, and the outcome using the green tea combination on the right.
This report follows on from our earlier story about the anti-wrinkle properties of white tea.
Of course much work remains to be done before this can ever be a treatment available from your local supermarket.
Details of the study appear in the Oct. 7 issue of the journal Crystal Growth & Design.
