What are some ways to treat sunburns?

It depends on the extent of the burn. If its just face or shoulders and face, you can topically apply cool compresses then slather the area with a mixture of aloe vera and cocoa or shea butter. If the burn is more extensive, you may want to soak in a tub of cool water. Take Ibuprofen or Acetaminophen for pain relief and drink copious amounts of water and electrolytes.
