Burns are injuries caused by heat, chemicals, abrasion, electricity, radiation, solar radiation or hot objects.
Burns are the most severe attacks to the skin. They can affect not only to this body but to the tissues or organs found underneath the skin.
Types of burns
According to its depth, burns are classified:
- First degree burns: These are produced in the epidermis or outer layer of skin. Their effects are milder and characterized because the skin becomes red, inflamed and painful. Skin usually needs 7 to 10 days for self-regeneration.
- Second degree burns: They also affect the lower layers of the skin. In addition to the above effects, they can cause blisters. They may produce scarring.
- Third degree burns: These are the worst because, besides affecting the entire skin, they also imply the tissues underneath it. They are responsible for large scars that prevent the regeneration of the skin and require skin grafting. Paradoxically, these type of burns produce less pain due to the destruction of the nerves that would have to report damage to the brain.
