The New York University (NYU) Langone Medical Center recommends covering a deep grease burn with a cool moist dressing to remove heat. Phys.org suggests removing any clothing or jewelry before the injury has a chance to swell by cutting around any clothing that is stuck to the burn. Victims and those assisting them must avoid oily products, including butter and ointments, which hold in the heat and increase the damage to tissue.
According to the NYU Langone Medical Center, most grease burns are deep partial-thickness burns or full-thickness burns. These second and third degree burns usually cause scarring and take three or more weeks to heal. Full-thickness burns only heal at the edge of the wound unless doctors perform skin graphs.
According to the University of Rochester Medical Center, individuals experiencing large second degree burns and those with third degree burns require medical care. In addition, children and the elderly require a doctor's care for any burn. Burns to the hands, face, genitals or feet require medical attention. In addition, a doctor needs to examine any charring of skin or blisters larger than 2 inches.
Burns are open wounds and subject to infection. The University of Rochester Medical Center recommends seeing a doctor for burns that become infected. Signs of infection include redness, swelling, discharge and a bad odor.
