Did you know that green tea promotes skin health by protecting the skin from UV radiation damage and thus improving skin quality?
According to one study, supplementing with green tea catechins increased oxygen flow to the skin. Increased blood flow will not only result in better looking skin, but also healthier skin cells overall. The same study also found green tea to improve elasticity and water content of the skin while reducing roughness and scaling.
Antioxidants like catechins protect cells from damage by free radicals. It guards against oxidative stress and can even protect against UV damage, reducing your possible risk of skin cancer.
These studies and others like them are part of the reason we are seeing more and more cosmetics and skin creams containing green tea. But while slathering something on your skin might deliver some benefits, ingesting something and therefore making it a part of you certainly will.
