Hold a minor burn received from a curling iron under cool, running water for 10 to 15 minutes, or until the pain diminishes. Cold compresses or submersing the affected area in cool water also eases the discomfort according to Mayo Clinic. Avoid ice as a first-aid measure.
Covering the burn with a sterile gauze bandage helps soothe the pain resulting from a curling iron burn. The covering keeps air away from the affected area while offering protection from possible infection. Over-the-counter pain relievers are also an effective aid to relieve discomfort. Aspirin, ibuprofen, naproxen and acetaminophen are options to consider.
