For how long dies a second 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.
