For the phenomenon of scar proliferation, it usually belongs to the result of over-repair of fibrous tissues after the body has been traumatized. Patients can use medication, surgery and other treatments to inhibit scar proliferation and improve its appearance. 1. Medication: In the early stage of scar proliferation, silicone gel, allantoin gel and other drugs can be used to inhibit scar proliferation; old scars can be injected with glucocorticoid drugs, such as Triamcinolone acetonide injection, to soften the scar and promote scar atrophy to improve its appearance. 2. Surgery: For hyperplastic scars that affect the appearance or function, if conservative treatment is ineffective, the surgeon can choose surgical excision treatment. If the scar is over-contracted and causes atrophy, keloid contracture release can be chosen as the treatment. 3. Other treatments: mainly refers to laser therapy, pressure therapy, cryotherapy, radiation therapy, etc., so as to improve the patient’s local scar hyperplasia phenomenon. When the patient has scar hyperplasia, if there is a willingness to treat it, it is recommended to go to a regular hospital as soon as possible, and cooperate with specialists to standardize the treatment, and avoid blind self-medication to avoid adverse consequences.
