In the quest to refine youth-preserving natural treatments, scientists have conducted experiments which showed light-emitting diodes (LEDs) and a cream based on green tea extract may help smooth facial wrinkles.

Non-invasive phototherapy has been used to treat skin imperfections for decades, but German scientists believe combining it with antioxidant-rich great tea lotion will take the treatment to a new level by eliminating potentially harmful reactive oxygen species produced by light therapy.

In the study, the researchers applied a daily combination of LED light and green tea cream to the wrinkles of a human volunteer for one month and found it produced smoother skin, including “less pronounced wrinkle levels, shorter wrinkle valleys and juvenile complexion,” they say.

The results prompted them to hail the experiment as opening a new way to effective, safe and non-surgical rejuvenation programs, in addition to shedding new light on the impact reactive oxygen species have on cellular aging.

Those looking for ways to boost their immunity and a preserve youthful appearance may also benefit from antioxidant nutritional supplements.
