What are some things i can do for a sunburn, and how long does it take to go away?

Keep sunburn cool w: Moist cool/cold compresses. Avoid alcohol containing products. Break off pieces of aloe vera plant & apply sap to skin. Consider non-steroidal anti-inflammatory meds to reduce pain. Don’t yank off peeling skin or burst blisters. Seek med care for severe pain, fever, lack of improvement of symptoms within several days or if a large surface area is blistered. May take a week or more to heal.
