Can any doc tell me what's the best treatment for 3rd degree burns?

If you truly have...: A 3rd-degree, or full-thickness, burn, unless it is very small or narrow and can heal in from the sides, it will need to be skin grafted to fully heal it. Partial-thickness (i.e., 2nd-degree) burns will heal in 1 to 3 weeks. If your wound is not fully healed after 3 weeks, you should see a general, plastic, or burn surgeon.
