Everyone’s skin and eyes can be affected by the sun and other forms of ultraviolet (UV) rays. People with light skin are much more likely to have their skin damaged by UV rays (and to get skin cancer), but darker-skinned people, including people of any ethnicity, can also be affected.
For some people, the skin tans when it absorbs UV rays. The tan is caused by an increase in the activity and number of melanocytes, which are the cells that make a brown pigment called melanin. Melanin helps block out damaging UV rays up to a point, which is why people with naturally darker skin are less likely to get sunburned, while people with lighter skin are more likely to burn. Sunburns can increase your risk of skin cancer, including melanoma. But UV exposure can raise skin cancer risk even without causing sunburn.
Aside from skin tone, other factors can also affect your risk of damage from UV light. You need to be especially careful in the sun if you:
Ask your doctor, nurse, or pharmacist if you are taking any medicines that could increase your sensitivity to sunlight.
No matter how sensitive your skin is to the sun, it’s important to know how to protect yourself from UV rays.
