At the Skin Study Center of University Hospitals of Cleveland and Case Western Reserve University it was determined that white tea extract protects against the oxidative stress of the skin that causes a breakdown in cellular strength and function. Researchers found that DNA damage that occurs in cells after exposure to sunlight was limited in skin cells protected by white tea extract. In general, researches believe that white tea extract’s antioxidant properties may provide anti-aging benefits. The same process of oxidative stress in skin cells that lead to immune system damage can also promote skin cancer and photo damage, such as wrinkling or mottled pigmentation. It appears that the white tea extract build’s the skin’s resistance to these stresses.
