Mexoryl SX Protects Against Photoimmunosuppression
Exposure of humans to solar radiation seems to be the major carcinogenic agent in the etiology of human skin cancers, at least for basal and squamous cell carcinoma [1, 2]. The biological effects of ultraviolet (UV) components of sunlight that could be involved in this tumoral development include DNA damage and epidermal hyperplasia (for review see ). moreover, there is increasing evidence that UV-induced immunomodulatory effects may be important in the development of skin cancer in humans . This immunosuppression can be detected by impaired generation of contact hypersensitivity (CHS) reactions to haptens in both humans  and laboratory rodents  and decreased reactivity against highly antigenic tumors in mice .
