Scars generally take 1-2 years to pass through the proliferative period, and some patients may continue for up to 10 years or so before gradually stabilizing, depending on the individual. Scarring is an abnormal growth and repair process of the local skin after the healing of a traumatic or surgical wound. This process can be completed and stabilized in as little as 6 months. The vast majority of scars take 1-2 years to stop proliferating, while a very small number can last up to 10 years before stabilizing. Localized redness, itching, pain and other discomfort may occur during the proliferation period, and the scar may continue to grow during this process. Patients can be treated with local glucocorticoid injections to flatten and soften the scars. For people with higher aesthetic requirements, surgical excision combined with superficial X-ray irradiation may be considered. During the period of scar hyperplasia, patients need to pay attention to avoid local scratching and stimulation. In case of recurrent scar infections and ulceration, patients are advised to seek medical advice.
