“Sunburns come in all different severities,” said Dr. Jennifer Tang, a dermatologist at the Sylvester Comprehensive Cancer Center at University of Miami Health System.

“The most common sunburn is just a little bit of redness, and that can result in some peeling,” Tang noted — but if it’s worse, “you can get really severe blisters.”

When a lot of the body’s surface is affected, your sunburn might resemble any other type of burn, she added.

“In that instance, when you lose such a portion of your skin barrier, you’re no longer able to regulate your temperature and you lose a lot of water,” she stated. “That’s when we recommend seeking care in the emergency room or a hospital.”

This would look like large, extensive blistering that covers a significant portion — probably around 30% — of your body, added Tang.

At that point, supportive care is necessary so doctors and nurses can help you stay hydrated and perform wound care to keep the burn clean, she said.
