What is the difference between 1st degree and 2nd degree burns?

The higher the degree, the higher the damage. First degree burns affect the first layer of skin on the outside, the epidermis. They happen after brief contact with something hot and do not require emergency medical attention unless there is a large area. Treatment typically includes running it under cold water and then applying aloe Vera or burn ointments. Second degree burns affect the epidermis as well as the dermis, the second layer underneath the epidermis. These can cause blisters and should be bandaged and kept clean.
