What is the correct treatment for first degree or second degree burns with closed blisters?

For first-degree burns, the treatment includes cooling the burn under running water for 10-20 minutes, applying a soothing lotion or aloe vera, and keeping the area clean. For second-degree burns with closed blisters, it's important to avoid popping the blisters to prevent infection; instead, clean the area gently, apply a sterile dressing, and consider using an antibiotic ointment. Over-the-counter pain relievers can help manage discomfort. If the burn shows signs of infection or does not heal, seek medical attention.
