If the skin of the human body is injured, it will more or less leave scars after healing. If the scars are from surgery, they are usually better, but if they are caused by trauma, they are usually more noticeable. Most people expect a medication or method to make scars disappear when they occur. However, scarring is not as simple as one might think, but rather quite complex, and the types and extent of scars vary greatly. Even with all the advances in medicine today, it is still impossible to fully understand the mechanics of abnormal scarring, let alone make all kinds of scars disappear. The effectiveness of the so-called “medications” in the media that can make scars disappear is questionable. From the standpoint of a plastic surgeon, we hope that the general public will have a correct understanding of scars, so that they will not spend a lot of money and get the opposite effect. The natural evolution of scars: Whether a scar is good or bad is determined by the degree of injury to the skin and how well the wound was treated, while the patient’s constitution and physical condition also play a part in the process. The general principle is that the faster the wound heals, the less scarring it will have; the slower the wound heals, the more severe the scarring will be. When a wound first heals, it will appear slightly red and swollen because of the proliferation of fibers in the scar. As time passes and the fibers gradually disappear, the scar will flatten and soften, and the color will gradually fade to white, usually called a mature scar, which usually takes about six months to a year. If the wound is more serious, infected, inflamed, or takes longer to heal, more fibers will be produced, and the scar will be thicker and larger, making it unsightly. If a hypertrophic scar is handled properly, the scar will gradually mature over a longer period of time and will fade to a certain extent. If it is not treated properly, it will become more serious. Some people due to their body type. Another type of hypertrophic scar, keloid, can develop, which grows outward beyond the original scar and can be quite troublesome to treat. Ideal scars and bad scars: Ideal scars are those that have degraded over a long period of time, resulting in thin, flat, white scars that are parallel to the skin’s grain pattern, making them difficult to detect. Undesirable scars include wide, depressed or raised scars, scars that form a long straight line, thick, red, swollen scars, and keloid scars. Ways to avoid undesirable scars: 1. Surgical wounds: After the wound stitches are removed or after the initial healing of the wound and the beginning of the wound, you can use no-sew tape to press on the wound until six months until the scar matures. At the same time, anti-scarring topical medication can be used, and the treatment cycle takes more than six months. Line-like scars and scars with redness and swelling are more obvious, can use silicone film pressure paste on the wound, silicone film must be applied for about 24 hours a day. 2, trauma scars: careful treatment of wounds carefully suture is the only way to reduce scars, also in the wound healing must be used silicone film pressure paste, until the scar is mature. Burn scars: Wear elastic clothing with strong pressure, usually for about six months to a year. Acne: In addition to cleaning the affected area, using fruit acids and taking medication to control acne, avoid squeezing the acne with your hands to prevent pits and scars. Adverse scar treatment: 1, hypertrophic scars: the latest treatment method, can also use long pulse 1064 laser treatment, closed the underlying blood vessels, to inhibit scar proliferation, improve the purpose of the symptoms. Steroids can also be used, directly injected into the scar, which can make the scar soften and subside. Steroids can be injected directly into the scar to soften it and make it fade away. Usually, the injection is fixed once every half a month until the scar softens and flattens out, and the red color of the scar will fade away and finally turn white. 2.White scars with a wide, thick, or unsightly appearance: Scar revision surgery can be performed, including scar excision and re-sewing, Z- or W-shaped revision, or laser resurfacing, etc., depending on the different scar conditions to determine the surgical method. Acne scars: microdermabrasion can be used to treat mild acne scars, and laser resurfacing or dermabrasion can be used to treat heavier acne scars. Burn scars: Scars are more serious and extensive, not easy to repair, usually only for the face and joints. Including scar excision, skin transplantation, tissue expander implantation. Correct concept: 1. Scars are traces left after healing of wounds caused by trauma or surgery, which will permanently exist on the skin and are not easy to remove. Through surgical revision or dermabrasion, etc., the unevenness or coarse and unsightly scars can be beautified into small, bland and not easily visible scars, but it is impossible to eliminate them. 2. Scars are not easy to repair, so scar prevention is better than treatment. If you want to repair scars, you have to wait until the scars are mature enough for surgery to be effective. 3, the types, causes and treatment of scars are very complex, we must consult a plastic surgeon in order not to make things worse.
