A burn is an injury to the skin caused by heat, chemicals, electricity, sunlight, or radiation. The body’s response to a burn depends on the burn’s severity, which can range from minor redness and swelling to life-threatening injuries requiring immediate medical attention.
- First-degree burns affect the outer layer of the skin, causing redness, swelling, and pain.
- Second-degree burns affect the second layer of skin, resulting in blisters, severe pain, and potential scarring.
- Third-degree burns penetrate through the skin, destroying it and possibly the tissues underneath.
