For the scars that are easy to leave after injury, the doctor reminds us to intervene as soon as possible to fight the scars. Huang Jiyi, director of plastic surgery in Shu Tian Clinic, said that the process of wound healing can be divided into four stages: vasoconstriction, inflammation, proliferation and maturity. The factors that affect scar quality include the mechanism of injury: the way of injury will affect scar and the area of wound. Generally, wounds smaller than 0.2 cm will not have scars, but injured parts: wounds in high-activity areas such as chest and elbows will be more obvious, whether they are infected with physique, that is, the physique of crab feet, the growth period and other periods with good tissue repair ability.
There is a trilogy against scars:
The first part is to avoid scar formation: when a wound occurs, different treatment methods, such as suture and artificial skin, are adopted according to the condition of the wound, so as to shorten the wound healing time, reduce inflammatory reaction, accelerate wound healing and avoid scar formation.
The second part promotes scar repair: after wound healing, laser treatment can improve vascular proliferation, and at the same time * * * fibroblasts produce new collagen to promote scar repair and inhibit scar formation after wound healing. After laser treatment, we should pay attention to avoid excessive sun exposure. You can apply ointment or emulsion on local ice, and don't rub the position irradiated by laser.
The third part is to prevent scar from growing again: using local pressure methods, such as silica gel membrane and beauty tape, to inhibit the growth of fibroblasts and prevent scar from growing again.
Huang Jiyi reminded that the correct attitude towards scars is to adopt different nursing methods at different stages from the formation of wounds, so as to reduce the chances of scars and achieve perfection and seamless.
