The best time to treat scar enlargement is early scar formation, as well as the entire process of scar development, which requires aggressive treatment. In general, there are three main treatment principles for scar growth: i. Early intervention: There is a large amount of data to support that silicone agents, compression therapy and topical medications are effective methods for early scar intervention, and the earlier the results, the better. II. Combined treatment: Due to the complex formation mechanism of scars, the efficacy of a single treatment plan is often not obvious, and the combined application of multiple treatment plans is more effective, such as the combination between silicone preparations and onion extract preparations, drugs combined with surgery, drugs combined with laser treatment, surgery combined with superficial X-ray irradiation, etc. Third, adequate treatment: the development of scars is a long-term process, so it is necessary to adhere to long-term treatment. Therefore, the treatment of scars is not an overnight thing, but a long-term process. It must be treated early under the guidance of dermatologists, and combined treatment should be adhered to.
