Green Tea Gives Skin Healthy Glow
Green tea contains compounds called polyphenols, which help
eliminate free radicals. These free radicals can cause cancer by
altering DNA. Polyphenols also protect healthy cells while promoting
the death of cancer cells.
Cell biologist Dr. Stephen Hsu recently began studying the most
abundant green tea polyphenol, called EGCG, and its effect on skin
cells. Hsu and his colleagues compared the growth of normal skin cells
to those exposed to EGCG.
They found the EGCG reactivated dying skin cells.
"Cells that migrate toward the surface of the skin normally live
about 28 days, and by day 20 they basically sit on the upper layer of
the skin getting ready to die. But EGCG reactivates them. I was so
surprised," Hsu says in a news release.
He and his colleagues also found other ways that EGCG benefits skin cells.
findings indicate that EGCG may offer potential benefits for skin
conditions including psoriasis, rosacea, wrinkles and wounds.
The research appears on the online version of the Journal of Pharmacology and Experimental Therapeutics.
