What is the Science of Photoaging: How UV Rays Affect Your Skin and Health?

Skin is constantly exposed to environmental elements, such as ultraviolet (UV) radiation from the sun, as part of everyday life. Photoaging is the damage caused by sunlight and ultraviolet light rays over time. The skin is made up of three main layers, and sun damage is most prominent in the epidermis, the top layer. Constant exposure to UV radiation can cause wrinkles, age spots, and other visible signs of aging. UV rays can also cause cancer, a link that has been established by several scientific findings.

What are the Risks of UV Rays for Skin and Health?

Exposure to UV rays over time has direct consequences on skin and health, particularly when not protected by a sunscreen or sunblock. UV rays damage skin cells and can cause wrinkles, age spots and other visible signs of photoaging. Our skin’s natural defense mechanisms are overwhelmed by constant exposure to UV rays, thus allowing the sunlight to penetrate and damage the underlying layers of the skin.

Possible Health Effects of UV Rays

The most important health issue associated with UV radiation is the increased risk of skin cancer, also known as melanoma. Multiple studies have described a correlation between UV radiation and skin malignancies. Aside from increased risk of skin cancer, ultraviolet radiation can cause reddened and irritated skin and eye damage, such as cataracts and macular degeneration.
