How long does it take to heal a 4TH degree burn?

Healing a 4th degree burn, which affects all layers of the skin and underlying tissues, can take weeks to months, and often requires extensive medical treatment, including surgery and skin grafts. Full recovery may take a year or longer, depending on the severity and location of the burn, as well as the individual's overall health. Rehabilitation and physical therapy are often necessary to regain function and mobility in the affected area.
