How much time does a 2nd degree burn take to heal?

Second degree burns: Are defined by the presence of blisters, but can range from very shallow to very deep. In general, the best treatment (in my opinion) is to remove the blisters to prevent the possibility of a closed space infection. Wash with soap and water, pat dry and apply Bacitracin ointment and a dry dressing 2-3 times/day. If increasing pain, drainage or redness or if not healed in two weeks, see a doctor.

Depends on size: A second degree burn involves the dermis of your skin because the outer epidermis had to completely regenerate. The process can take 1-2 weeks for a healthy person to have a new skin layer cover the burn. Larger surface areas can take longer and you should see a physician to advise on proper care. The main issue is to prevent infection and provide a moist environment for the skin to heal.
