High doses of UV radiation kill most of the skin cells in the upper skin layer, and cells that are not killed get damaged. In it is mildest form, sunburn consists of a reddening of the skin called erythema.
This appears shortly after UV radiation exposure and reaches a maximum intensity between 8 and 24 hours. It then fades over the course of a few days. However, a strong sunburn may cause the skin to blister and peel, which is not only painful but also leaves the very white and new skin underneath unprotected and even more prone to UV damage.
A mild sunburn does not normally require a visit to the doctor. However, if there are severe symptoms, it is important to seek medical attention.
A doctor will ask about symptoms and medical history. A physical exam will be conducted and, for some cases of sun damage - you may be referred to a dermatologist.
