The main cause of skin aging is sun exposure. Skin changes: abnormal pigmentation, dull complexion, and wrinkles are few of the aging effects of uninhibited sun exposure.
UV radiation and visible light can trigger phototoxic and photo-allergic dermatitis that can leave affected people disfigured with diminished quality of life. The sun can also trigger autoimmune disease such as Lupus erythematosus which can be fatal.
Skin cancer is on the rise. Skin cancers are seen across all races. Solar UV radiation causes mutation and immunosuppression within the skin which culminates to cancer formation. Skin cancers such as melanoma and squamous cell carcinoma can be lethal if diagnosed late and left untreated.
