Skin is an important barrier of human body, and all kinds of surgery, trauma, burns and dermatitis will lead to skin damage and defect. During the healing process of skin injury, the body will release a kind of protein called collagen for wound repair. When the skin injury reaches a certain degree, the function of collagen synthesis and metabolism loses its normal inhibition and control, and it continues to be in a state of hyperactivity. Collagen extravasates excessively, resulting in excessive proliferation of collagen fibers and scar formation at the wound healing site. Scar is characterized by normal skin protrusion, irregular shape, red and hard benign mass, and severe cases are accompanied by symptoms such as contracture, itching and pain. If it grows excessively, it will affect the appearance or cause dysfunction, and may even become cancerous. Therefore, it is necessary to prevent excessive proliferation and contracture of scars when the skin heals.

Scar hyperplasia has internal and external causes. The internal causes are mainly scar constitution and estrogen level in the body, which are mostly inherited in the family; External causes are mainly skin injuries caused by various reasons.

Scar is the number one enemy of plastic surgery, and the good plastic effect may be completely destroyed because of the ugly scar after surgery, and even all previous efforts will be wasted.
