There are several types of burns from sunburns, heat burn, chemical burn, acid burn, to name but a few. Different types of burns affect the skin differently. Burns are categorised into three categories according to the severity. These are first-degree, second-degree and third-degree burns. Treatment and first-aid are given accordingly. Dr. Nivedita Dadu explains first-aid measures for skin burns.
