UVA and UVB are two types of ultraviolet rays from the sun. UVA rays have longer wavelengths and reach deeper into the skin, causing tanning, wrinkles, and early aging over time. UVB rays have shorter wavelengths and affect the skin’s outer layer, causing sunburn. They can also damage skin cells and raise the risk of skin cancer. While some sunlight helps the body produce vitamin D, too much exposure can harm the skin and eyes.
