Hypertrophic scars tend to occur in areas with high tension and many activities, such as chin, sternum, deltoid muscle, upper back, elbow, hip, knee, ankle and instep. 3. Foreign bodies fall into the wound: dust, talcum powder, fibers and residues of hair follicles, sebaceous glands and sweat glands can all cause tissue reactions, leading to scar hyperplasia. 4, infection: repeated infections, long-term exposure of wounds, excessive proliferation of granulation tissue, prone to hypertrophic scars or keloids. 5, skin pigment: there are many colored human pigment cells, which are also easily stimulated. The incidence of black keloids is 9 times that of whites; It is easy to occur in the period of pituitary physiological activity, such as adolescence and pregnancy. 6. Other factors: the angle between the incision and the skin is perpendicular to the incision of the skin, and the scar is the thinnest after healing; The greater the inclination angle, the wider the dermal scar and the more obvious the skin deformity.
