First of all, see if it is a scar constitution. If it is, it won't disappear again. If it doesn't, it will fade after a while, and it is ok not to take medicine. In addition, the degree of scar appearance is sometimes related to suture technology. Surgical suture wounds usually leave suture scars. Once the scar is produced, it is difficult to completely eliminate it. We can only prevent it as soon as possible. The prevention and treatment of needle scar should pay attention to the following points: 1. Nursing care after wound scab ① After wound scab, the scab skin should not be forcibly removed, but should wait for the scab skin to fall off naturally, so as to avoid the wound from losing the protection of hard scab and forming scars and causing pigmentation. At the same time, after the wound scabs off, we should pay attention to sun protection to avoid pigmentation of new skin caused by sunlight. In addition, patients should also pay attention to avoid eating irritating or pigmented foods such as pepper, soy sauce, ginger, garlic and wine in their daily diet to avoid scar hyperplasia and pigmentation. In order to promote wound healing, patients can eat more fruits and vegetables appropriately, and vitamin C should be supplemented appropriately if the wound is large. ② Patients should use cosmetics with caution during the recovery period, because some cosmetics contain a lot of chemicals, which may stimulate the wound and affect its normal healing. If the scar produced after wound healing really affects the appearance, it can also be removed by surgery, but you must choose a regular hospital and an experienced doctor during the operation to avoid lifelong regret caused by improper operation. (3) after the wound scabs, wait patiently for the wound to fall off by itself. People often don't like the dark and hard scab skin, or because of curiosity, they can't help but peel it off early. At this time, the epidermal cells being repaired have not grown completely, and without the protection of hard scab, it is easy to form scars and pigmentation. Occasionally, the newly grown epidermal cells will be taken away carelessly, which will also stimulate local inflammatory reaction and hinder wound healing. In addition, the wound will feel itchy when it heals. Scratching, scalding with hot water, rubbing clothes and other methods will stimulate local capillary dilation and granulation tissue proliferation to form scars. In terms of diet, irritating foods such as wine, pepper, mutton, raw garlic, ginger, mustard and coffee will also promote scar growth. If you eat drugs containing lead and gong, it will promote pigmentation; Sun protection cannot be ignored. Especially in midsummer, the sun is hot and full, and the newborn skin is immature, which is difficult to resist the ultraviolet radiation in the sun and is easy to form pigmentation; Cosmetics, soap, etc. Should not touch the wound. Because all kinds of cosmetics inevitably contain heavy metals and photosensitive substances such as lead, gong and silver, it will stimulate the increase of skin pigment. It can be seen that as long as you can treat the wound scientifically and seriously, you will be able to limit the scar and pigmentation to the lightest degree. 2. Prevention of keloid: keloid hyperplasia is an important complication of trauma and trauma. The preventive measures mainly lie in the immature stage before and during scar formation. The main purpose is to remove all kinds of factors that cause scar hyperplasia as much as possible, reduce the growth of scar, prevent all kinds of deformities and dysfunction caused by scar on the body, and pay attention to minimize mechanical, chemical and thermal stimulation to the affected area when it is serious, so as to avoid repeated pulling, friction rupture and infection. I usually eat alkaline food such as kelp. Because these foods can improve their scar constitution if they are eaten for a long time. 3. At present, the treatment of keloid is very common, but the cause is still unknown, which brings great difficulties to the treatment. How to inhibit the crazy proliferation of fibroblasts and prevent their recurrence and continuous growth has become a difficult problem in the medical field today. At present, there are the following treatment methods: surgical resection, grinding, laser, radiation, local sealing, freezing and so on. Monotherapy often fails to achieve satisfactory results and easily worsens the affected area. For example, the recurrence rate of surgical resection is high, laser sealing is often unbearable, and there are many diseases, such as irregular menstruation in women and impotence and obesity in men. Skin abrasion, laser and freezing can't prevent recurrence, which makes many patients and doctors feel very embarrassed. Many doctors even answer patients: "Keloid is more difficult to treat than cancer." In fact, this view is quite one-sided.
