You know it depends. How fair skinned is the individual? How bad were the sunburns? Overall, the more sun exposure (especially sunburns) an indivdual has, the more chances they have of having sun undermine as an adult. I think just about everyone has had a few sunburns in their life, but I think those who are at higher risk are those who are very fair skinned, those who take certain medications (like acne medications) that make your skin more sensitive to its effects, and those who continually sunbathe and don't really protect themselves.



As for reversing sundamage, it's really not possible to do so. That's why there is such concern with skin exposure and skin cancer. Skin cancer can be very malignant (spread to other parts of the body, both inside and out), and should be watched for with a careful eye.



The easiest technique to feel better about something that concerns you on your skin is to talk to your physician. They have trained eyes to notice things that we may not see. But it's always wonderful to be observant of things that happen to ourselves.



In nursing school, I've learned that there are things called the "ABC's of skin cancer". I went to the following website and pasted what they said here for you to read.

Develop a regular routine to inspect your body for any skin changes. If any growth, mole, sore or skin discoloration appears suddenly or begins to change, observe your dermatologist. Each of the skin cancers can be treated if detected early.



The ABC's of skin cancer include any alteration or development in a mole or skin growth that should prompt you to observe a dermatologist. These may include;



A- Asymmetry- You should notice the normal look of your moles or growths, for example, if one half of the mole or growth does not match the other half.



B- Border Irregularity - If the edges of the growth are ragged, notched or blurred.



C- Color - The pigmentation of the growth is not uniform. Shades of tan, brown and black are present. Dashes of red, white and blue contribute to the mottled appearance.



D- Diameter - If the width is greater than 6 millimeters (about the size of a pencil eraser), it could be an indicator of an abnormal skin growth. Generally, any new mole growth should be a concern.

This website also has links to photographs of the abnormalities that you could be watching for on your own skin.



Protecting your skin with UVA and UVB sunblock (and the skin of children) is really important. We all forget or obtain caught without it sometimes, but trying to keep yourself covered (no pun intended) is the best technique to go.
