Green Tea water contains abundant Tea polyphenols, which can清除人体有害自由基 and block the process of lipid peroxidation. Additionally, the tannic acid in green tea water can also prevent the formation of wrinkles. A Japanese study confirmed that washing the face with green tea water has anti-aging effects, outperforming skincare products containing vitamin E, and can prevent wrinkles and reduce dark circles.

You can wash your face daily with green tea water instead of tap water, or apply green tea water to your face and gently pat it to promote skin absorption of tea polyphenols. The green tea water does not need to be too strong; the concentration for daily drinking is sufficient. It is best to use green tea water brewed on the same day, as the tea polyphenols in overnight tea will oxidize, reducing its skincare effects.
