They are tissue damage caused by the application of heat, chemicals, electricity or radiation to the body. The extent of the damage (depth of the burn) is a result of the intensity of the heat (or other exposure) and the duration of the exposure.
They are distinguished in:
Partial thickness: Grade 1 burns affect the surface layers of the skin. The 2nd degree extends to various thicknesses in the skin (with the formation of bubbles), and in a part of the skin.
Total thickness: Grade 3 is characterized by destruction of all elements of the skin and thrombosis of the subcutaneous plexus.
For the treatment of any degree of burn, it is better to visit your personal dermatologist as soon as possible.
