Green Tea and Red Light—A Powerful Duo in Skin Rejuvenation

Abstract Objective: Juvenile skin has been the subject of intense research efforts since ancient times. This article reports on synergistic complementarities in the biological actions of green tea and red light, which inspired the design of a green tea–assisted facial rejuvenation program. Background Data: The approach is based on previous laboratory experiments providing insight into a mechanism by which visible light interacts with cells and their microenvironment. Methods: After 2 months of extreme oxidative stress, green tea–filled cotton pads were placed once per day for 20 minutes onto the skin before treatment with an array of light-emitting diodes (central wavelength 670 nm, dermal dose 4 J/cm2). Results: Rejuvenated skin, reduced wrinkle levels, and juvenile complexion, previously realized in 10 months of light treatment alone were realized in 1 month. Conclusion: The accelerated skin rejuvenation based on the interplay of the physicochemical and biological effects of light with the reactive oxyg...
