UV radiation, emitted by the sun, encompasses three distinct types: UVA, UVB, and UVC. Among these, UVC rays are predominantly absorbed by the Earth's ozone layer, preventing their direct contact with the surface. However, UVA and UVB rays possess the capability to penetrate the atmosphere, thereby exerting their effects on the skin. UVA rays, known for their longer wavelengths, have the ability to infiltrate deeply into the skin's layers, thus promoting premature aging through mechanisms such as collagen breakdown and the generation of free radicals. On the other hand, UVB rays, characterized by shorter wavelengths, primarily influence the skin's outermost layer. They contribute to the manifestation of sunburn and play a significant role in the development of skin cancer by inducing DNA damage and mutations in skin cells. Understanding the distinct properties and effects of each type of UV radiation is crucial in implementing effective sun protection strategies to safeguard the skin's health and mitigate the risk of sun-related damage and diseases.
