In life, falls and abrasions, burns and scalds, surgeries, and even acne can leave scars on the skin. Scars, although they are a natural product of our body’s healing, but if they are not recovered properly, they are really aesthetically displeasing. We may even feel unconfident because of some scars, for fear of being exposed and seen by others. Scars not only affect the appearance and psychology, but also directly affect the health of the body in serious cases, regardless of the size of the scars should be taken seriously, and treated in a timely manner with the help of a professional doctor, in order to avoid leading to more serious consequences A. Why does scarring occur? When the dermal layer of the skin is damaged, scarring may occur, but if the injury is shallow, scarring will not occur. Scratches with sharp instruments, burns, ear piercing, surgeries, vaccinations and other behaviors may leave scars. Keloids and hyperplastic scars are the body’s over-tissue response to dermal damage, that is, the repair process is too violent to stop the car, the local fibroblasts and collagen overproduction, resulting in new scars “jumping out of the skin”. Both keloids and hyperplastic keloid scars are characterized by tissue growth, i.e., a protrusion of flesh. The former is more expansive, growing into undamaged areas and increasing in size over time, while the latter is only active in the damaged area and shrinks over time. You can’t blame the body for scarring, after all, it’s not an intelligent AI, but there are solutions to these problems, so don’t worry about staying with it until you die. Second, how to prevent the formation of scarring? The formation of scarring is related to two factors: inflammation and trauma. So the best prevention is not to get injured. For people with a history of keloids or proliferative scarring: 1. You need to try to avoid behaviors such as piercing ears or giving piercings to other parts of the body. 2, Avoid mole removal procedures (unless deemed necessary by your doctor). 3, the appearance of acne, wounds, infections, etc. It is recommended to treat the situation as soon as possible to minimize the area of inflammation. 3. How should I handle an injury? Correctly treat the wound, timely debridement, disinfection, and suture treatment if necessary. Control inflammation and infection, to avoid further aggravation of local inflammation and infection, wound prolongation, resulting in increased risk of scar formation. No scarring, from you and me. Maintaining moisturization and accelerating wound healing in the early stages of wound healing may reduce scar formation. Therefore, we can choose to apply topical moisturizers, growth factor ointments, and antibiotic ointments. Avoiding wound pulling can be done by using reduced tension tape to pull the wound closed after applying moisturizers and wrapping it with a dry bandage or gauze while preventing hand digging. Hyperpigmentation is common after the wound has healed and is exacerbated by UV rays, so a good hard sunscreen (for physical coverage) or sunscreen on the healing area is needed.
