White Tea Extract:

White tea is the unfermented, uncured tea leaf. As with green tea, which is heat cured, white tea comes from the plant Camellia Sinensis plant, which grows in many Asian countries. Other Chinese teas made from Camellia Sinensis include oolong tea and black tea, as well as jasmine tea (which is jasmine-infused tea leaves).

White Tea Extract contains several polyphenols and anthocyanidins, the antioxidant activity of which is higher than that of red wine and green tea. Standardized White Tea extract used in Herbal Spray provides protection against free radical damage, which accounts for more than 80% of the signs of premature aging.

The catechins contained in green tea have been long recognized for their benefits for skin. Some formulations based on it are now being marketed as natural suncreens. However, recent evidence indicates that white tea may be significantly more effective than green tea in some important ways (especially in regard to skin aging) and that the differences between the two are just as noteworthy as their similarities. A study* by Dr. Camouse and colleagues from University Hospitals, Cleveland, Ohio, compared UV-protection effects of topical green and white tea and found them to be roughly equivalent. In another study** researchers looked at two key effects that help slow down skin aging: antioxidant activity (ability to neutralize harmful oxygen free radicals) and the ability to inhibit matrix metalloproteinases (MMP). Excess MMP activity (often seen in older people) contributes to skin aging. The research indicated that out of a series of 21 plant extracts, white tea showed the greatest level of activity (per milligram of extract) both as an inhibitor of key MMP subtypes (collagenase and elastase) and as an antioxidant. The data indicate that white tea may be about 3-6 times more effective than green tea as a skin matrix protector. For these reasons we use powdered white tea extract (sourced from a highly accredited facility in China) instead of green tea extract in our formula, and, like all out ingredients, it is stored in containers purged of oxygen with inert blanketing gas to prevent oxidization.
