After a wound forms, a series of physiological mechanisms are triggered, leading to the gradual regeneration of injured tissues, known as healing. This process involves the renewal of collagen fiber cells, ultimately replacing damaged fibrous tissue.
Healing is a natural process that varies based on individuals and the affected injury areas. Factors influencing the duration and final scar appearance include:
- Patient’s age
- Skin type
- Tobacco use
- Cardiovascular health
- Genetic predisposition
Regardless, normal healing generally consists of three phases. The first phase begins immediately after the injury and lasts about two weeks, involving the body’s cleansing of the wound by removing damaged or necrotic tissue.
The second phase, lasting from 3 to 6 months, sees the wound turning red as collagen production and blood vessel renewal intensify.
The third and final phase typically spans 1 to 2 years. The skin gains elasticity, and the wound transitions into a whitish scar.
