Green Tea Gives Skin Healthy Glow
Researchers say finding could lead to new treatments for skin diseases
THURSDAY, May 15 (HealthScoutNews) --The skin-healing properties of green tea
may help scientists develop new treatments for skin disease and wounds, say
researchers at the Medical College of Georgia.
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.
The 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 .
