Scars always bring both physical and psychological pain to people, and since medicine has not yet conquered scarring, any treatment can only improve the appearance. Therefore, instead of long scar treatment, it is better to prevent scars in advance, especially some superficial scars. Clinically, often superficial scars look slightly rough, sometimes with pigmentation or pigment loss, but locally soft and without functional impairment. No special treatment is usually done. They are commonly seen in areas of skin abrasions, superficial infections of skin pus, superficial second-degree burns, and donor area healing calendars where thick pieces of skin are cut and removed. Superficial scars are generally non-functional and will become less visible over time. Superficial scars are therefore a milder type of scar. I. Preventing scars, its effect and significance is far better than treatment Scar formation generally starts to become red and hard after 2 weeks of wound healing, and then grows slowly. If we do a good job of scar prevention in time when the wound is treated, pay attention to diet, and use scar products such as Scarke, Conrad, and MepiCare in time, we can prevent scars before they happen, instead of growing scars and then treating them, we can prevent them from growing. Second, when there are scars, early treatment is most important The early stage of scars is within 3-6 months after the healing of trauma. Early scars are in the unstable stage, red, painful and itchy. If it is decomposed in time during the unstable period to inhibit the fast-growing collagen cells, it will get twice the result with half the effort and be able to recede redness, stop itching, relieve pain, soften, and finally leave only a trace, which is quite effective. Third, long time scars, especially after chemical substance burns in exposed areas should be treated Fourth, the diet should be noted during scar treatment Chinese medicine believes that people are a contradictory unity, and the physiology of various parts keep close contact with each other, the whole body affects the local, and the local contact with the whole, therefore, attention should be paid to the diet: spicy and stimulating foods, such as beef and mutton, dog meat, animal offal, pork, rabbit meat are not eaten. Seafood, chili peppers, garlic, melon, orange, pumpkin easy on fire eat less. Wine not to drink. Pigmented food such as coffee, soy sauce, vinegar eat less. Eat more seaweed, red dates, cinnamon, etc. The diet should be light, intended to strengthen the benefit of Qi and generate fluid, in addition to dryness and relieve itching.
