If the blisters are small, no special treatment is needed; if the blisters are significantly larger, they can be punctured with a sterile needle and attention is paid to keeping the blister epidermis perfect. After a few days of treatment, the tumor may form purple-red patches and scabs, generally 1-2 weeks later, let the scabs fall off by themselves, so that the scars are smaller. Topical medication is usually applied twice a day, first with water and then with ointment. Without any special circumstances, a follow-up visit to the plastic surgery clinic will be made on Thursday after one month. If local redness and swelling are obvious and exudate is high, please seek medical attention or consult the children’s hospital.
