A third-degree burn is a severe type of burn that affects all layers of the skin, including the epidermis, dermis, and underlying tissues. This type of burn can result from prolonged exposure to heat, chemicals, or electrical sources. The skin may appear white, charred, or leathery, and it often lacks sensation due to nerve damage. Treatment for third-degree burns typically requires medical intervention, as they can lead to serious complications. Healing may involve skin grafts and extensive rehabilitation. It is crucial to seek immediate medical attention for third-degree burns to minimize risks and promote recovery.
