Photoprotection by green tea polyphenols



  • The relationship that humans have with sun exposure is delicately balanced between the positive effects that this form of radiant energy provides and the negative aspects that overexposure engenders. The benefits of sun exposure include its positive psychological actions, the role it plays in vitamin D metabolism, and the value it has as a therapeutic agent in cutaneous and systemic disease. The adverse consequences of overexposure include acute UV-induced erythema (i.e., a sunburn), nonmelanoma skin cancer (cutaneous squamous cell and basal cell carcinoma), melanoma, photoaging of the skin, and UV-induced immunosuppression.
