After trauma, surgery, burns, scalds and other injuries occur, a person’s skin develops scars that can seriously affect the aesthetics of one’s appearance. There is no ideal treatment for scars, so doctors often use a variety of measures to prevent and reduce scars. The focus of scar prevention is early, ongoing and long-term, with the main measures being medication + pressure. Medications should be used as early as possible after the wound has healed. Common scar softening medications such as cumene cream and Conradipine should be applied evenly to the scar several times a day and massaged to allow the medication to penetrate the scar tissue. Scar patches can also be used. Scar patches are silicone gel films made of new medical polymer materials, which not only prevent scars, but also gradually soften and flatten early scars that have been raised, and make pigmentation lighter. When you first start to use the scar patch, you should apply it for 6 to 8 hours a day, and then gradually increase it to 24 hours a day for continuous use. Pressure should be used in the early stage of scar formation by elastic compression. Different elastic sets are available for different parts of the scar, such as elastic mask, jaw set, upper limb set, elastic glove, etc. If it is found that the body of the part wearing the sleeve turns blue and purple when using, the elastic sleeve should be taken off immediately and the elasticity should be adjusted until it is suitable. After the affected area is adapted to the pressure, the pressure time can be gradually increased until 24 hours of continuous pressure. The compression method should be adhered to for 6 months to 1 year until the scar is completely flattened and softened, and the color becomes white. For scars that seriously affect the appearance and function, it is best to remove them by surgical means and then take the above measures, which can also achieve satisfactory results.
