If you get a blister after burning your hand while frying, first rinse it with cool water to take away the excess heat and prevent further damage to the skin. If the blister is small, less than 2-3mm in diameter, no special treatment is needed, you can apply Longzhu ointment or Jingwanghong ointment twice a day, and it will gradually get better in about 2 weeks. If the blister is large and the skin is difficult to absorb by itself, you can use a needle to puncture it after disinfection, squeeze out the herpes gently, taking care not to tear off the wall of the blister, and apply recombinant bovine basic fibroblast growth factor gel and mupirocin ointment to reduce inflammation. If there are only blisters, no ulcers and the burns are relatively shallow, there is no need to bandage them, just expose them directly, do not get wet for 1 week, change the medication regularly, and they will gradually recover in 2-3 weeks.
