Fixderma Shadow SPF 30 consists of Octyl Methoxycinnamate, Avobenzone and Micronised Zinc Oxide. Octyl Methoxycinnamate is a sun blocking agent that absorbs UV rays and helps in reducing scars. Avobenzone protects skin during periods of sun exposure and does not let the radiation penetrate through the skin. Micronised Zinc Oxide reduces sun damage by absorbing UV rays and robbing them of their harmful power.
