Ouch! Redness and mild pain are characteristic of sunburn.

Sunburn (First-Degree Burns)

Sunburn is skin damage from the sun's UV rays. Most sunburns result in redness, heat to the touch, and mild pain, affecting only the outer layer of skin (first degree burns). Sunburn usually appears within hours after sun exposure and may take several days to weeks to fade. Pain relievers such as aspirin or ibuprofen, cold compresses, and aloe, hydrocortisone, or moisturizing creams may help reduce pain and discomfort.
