There are many situations in daily life that can lead to skin damage; car accidents, fights, sports, etc. can all cause trauma scars. Usually caused by trauma from external objects such as collisions, blows and chemical erosion, scars are a result of biological cellular repair. If the trauma occurs on the face, the most worrying thing is to leave scars. Scars are very aesthetic, especially if the facial injury leaves scars, it will make one’s image greatly reduced. Trauma scars are often seen in adolescents and adults with special jobs, but of course various accidents are also the main cause of scars, mainly on the back of the shoulders, forehead, limbs, abdomen, etc. Some people, due to their peculiar constitution, will show crab feet, centipedes and other forms with hard appearance and irregular edges during the healing process in which fibrous tissues are involved. In some patients, the color of the scar area tends to be dark red, and symptoms such as pain and itching appear. So how to prevent the formation of trauma scars? First, prevent infection. Preventing wound infection is the key to avoid leaving scars. Avoid sweat from entering the wound in hot weather, and don’t use water for the wound in order to keep cool. Infection will cause damage deep into the subdermis, so that the epidermis can not be regenerated, and the proliferation of granulation tissue to fill the defect will form scars. Skin wounds should be treated in a timely manner at the hospital, to prevent infection, do not use iodine disinfection, so as not to cause hyperpigmentation. Second, pay attention to protection, let it naturally decab, not to tear off artificially by hand, otherwise it will tear the new tissue under the scab, causing permanent pigmentation scars. For the red and tender skin after the scabs fall off, you should not use any cosmetics to cover it up, and you can use hydrating mask to moisturize it, and aloe vera gel for care. You can also apply scar removal cream to inhibit scar proliferation. Third, the correct stop itching. It is normal for wounds to itch in summer, so patients should be careful not to scratch the wounds with their hands, and not to rely on clothes and other friction to stop the itching, so that these local stimuli do not lead to inflammatory reactions in the connective tissue. Fourth, summer sun protection. Avoid sunlight during the postoperative recovery period to prevent the formation of hyperpigmentation by UV stimulation. Fifth, pay attention to diet. If you drink a lot of alcohol after injury, or ingest stimulating foods such as chili, mutton, garlic, ginger, coffee, etc., it will promote scar proliferation. Eat more fruits, green leafy vegetables, eggs, lean pork, meat skin and other foods rich in vitamin C, E and essential amino acids for human body, which will help the skin to recover as soon as possible and prevent trauma scars. If you don’t take care of your trauma scars properly, it’s likely to cause scarring or hyperplasia. Once these occur, don’t be too alarmed, but go to a professional scar department in time so that you can identify the cause and prescribe the right medicine as soon as possible to reduce your condition.
