The correct response is inflammation, which is a fundamental biological process that is part of the body’s immune response to injury and infection. When tissues sustain damage or are invaded by pathogens, the immune system activates a cascade of events that leads to inflammation.

This response is characterized by redness, swelling, heat, pain, and sometimes loss of function in the affected area. The redness and swelling are due to increased blood flow and the accumulation of fluid and immune cells at the site of injury. This influx of blood brings necessary nutrients and white blood cells that help to fight infections and initiate healing.

Inflammation serves several purposes: it isolates the affected area, prevents further injury, and promotes healing. The process is generally protective and is vital for recovery from injuries and infections. It is a clear indicator that the body is actively working to heal itself.

Understanding this process is crucial in fields like cosmetology, as it highlights how skin might react to certain treatments or products, reinforcing the importance of monitoring client reactions during services.
