The formation of scars depends on the condition of your wound and whether you have a scarring constitution. It is recommended that you go to the hospital as soon as possible. If the wound is deep and infected, it will be even more troublesome. I hope the following article can help you. How are scars formed? 2008-11-25 Source: China Plastic Surgery Network (517mr.com) Scars are a repair response of the body to tissue damage. When the skin damage reaches the dermis, (such as cutting injuries, skin and soft tissue lacerations, surgical incisions, etc.) or large-area epidermal defects (such as abrasions, burns, etc.). The epidermis in this area cannot regenerate and will be replaced by dermal fibroblasts, collagen and proliferated blood vessels. , so scars appear. Theoretically, all injuries to the dermis will leave scars, but everyone's repair ability is different, so the degree of scar formation is also different. What factors are related to the formation of scars? 1. Skin tension. Hypertrophic scars are more likely to occur in areas with high tension and high activity, such as the front of the chest and around joints. 2. Skin pigment: Pigment cells are active in people of color. People with darker and thicker skin have a much higher incidence of scarring than people with whiter and thinner skin. 3. Wound infection and inflammatory stimulation can easily produce hypertrophic scars. 4. Improper incision selection and long wound healing time will also affect scar formation. 5. Scar constitution refers to the tendency of some people to form keloids easily. If they undergo surgery, minor trauma or even mosquito bites may cause keloids to appear locally. Commonly used non-surgical therapies for scar treatment: Intra-scar injection of steroids: suitable for small and medium-sized hypertrophic scars and strip-shaped hyperplasia after surgery. Radiotherapy: X-ray superficial irradiation or isotope patching can be used. It is effective for new scar hyperplasia. Laser treatment: Using the imported Vasculight laser beauty machine, selecting a specific wavelength and pulse width for laser irradiation, it can flatten and soften fresh hypertrophic scars and make the blood vessel congestion disappear. Local drug application: Use scar softening patch, scar diathermy patch, etc. to promote scar softening and absorption. Compression therapy: Using elastic bandage and elastic mesh to compress for one to three months has a certain effect on preventing and treating hypertrophic scars. Commonly used surgical therapies for scar treatment: Laser dermabrasion: suitable for various small depressed scars, uneven incision scars, abrasion scars, and skin infection scars. It can flatten the scars and grow new epithelium on the scar surface. .
