Blisters formed from burns will disappear in a few days, usually related to the degree of the burn, and need to be analyzed on a case-by-case basis. Blisters are usually seen in superficial second-degree burns (injuries to the epidermis and part of the dermis) and partial deep second-degree burns (injuries to the epidermis and most of the dermis). In the case of superficial second degree, the blisters are small in extent and size and can usually be completely absorbed in about 1 week; if the blisters are larger in size, the absorption time is often extended and takes 2 weeks or more. In the case of deep second-degree burns, it usually takes 3-4 weeks to recover. In addition, active cooperation with treatment can also promote the absorption of blisters, thus shortening the time it takes for them to disappear. After the blisters appear in the patient’s burns, he/she needs to go to the burn department of a regular hospital in time, and a professional doctor will take appropriate treatment measures according to the specific situation. If necessary, the blister fluid can be pumped out under strict disinfection to promote the recovery of the blisters as soon as possible.
