Sunscreen vitamin C

Oil free sunblock with Vitamin C.

Sunblock is a topical preparation, such as a lotion, cream, or gel, that is applied to the skin to protect it from the sun’s harmful ultraviolet (UV) radiation. Its primary purpose is to prevent sunburn and reduce the risk of premature aging and skin cancer. Sunblock works either by absorbing UV radiation, preventing it from reaching deeper skin layers, or by reflecting the radiation away.
