The three types of burns include first, second, and third degree burns. A first-degree burn is when there is redness on the epidermis with minor pain. Sunburns can be included within first-degree burns. Second degree burns cause blistering of the skin and may be more or less painful depending on nerve exposure and damage. Second-degree burns involve the papillary dermis and sometimes the reticular dermis and may require a skin graft if severe.

In third-degree burns scarring will occur, hair shafts and keratin are lost, and a skin graft will likely be necessary.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
