A burn with a 1cm blister may heal on its own without picking it. Since there is less fluid in a 1cm blister, even if the blister is not punctured, it can gradually absorb and heal on its own, and the fluid will usually dry up on its own in about 1 week. However, for blisters that are about 2cm in size or have a higher risk of rupture, it is recommended that they be treated in a hospital. Usually, a sterile syringe is used to puncture the blister to suction out the fluid, and sterile gauze is used to bandage the blister. Topical medication that promotes skin barrier repair, such as recombinant bovine basic fibroblast growth factor gel, can also be used. When the patient is burned, if the blister is small, picking is not recommended. If the blister is relatively large, it is recommended that the patient go to the hospital in a timely manner and be handled by a professional doctor.
