Sunscreens protect the skin from dangerous ultraviolet sun rays. Sunscreen helps the skin to remain healthy by reducing the risk of skin cancer, protecting against sunburn and preventing premature aging.
Function
Sunscreens are chemicals that are used to reflect, absorb or scatter sunlight and dangerous ultraviolet radiation from entering the skin. Sunscreen is found in lotions, gels, sticks, sprays and lip balms.
Skin Cancer
Ultraviolet rays increase the risk of developing a variety of skin cancers, including melanoma which is the leading cause of all skin cancer deaths. Sunscreen blocks ultraviolet rays from penetrating the skin, thereby reducing the risk of skin cancer.
Sunburn
Sunburns are first- and second-degree burns caused by sun exposure. Sunscreens help protect the skin by keeping sun rays from burning the outer layer.
Premature Aging
Sunscreens protect the skin from the ultraviolet rays that cause sagging, burning, spots and wrinkles. Sunscreens keep skin proteins like collagen, keratin and collagen in the skin, which helps it remain healthy, smooth, firm and youthful.
Prevention/Solution
Dermatologists recommend using sunscreens with an SPF of 15 or higher to properly protect the skin. Sunscreens should be used by everyone, regardless of skin type, and they should be applied to all exposed parts of the body 15 to 20 minutes before going outside.
