Scar hyperplasia, i.e. proliferative scarring, does not usually go away on its own. The appearance of the scar is improved by general treatment, medication (silicone-based gels, tretinoin, etc.), and surgical treatment. 1. General treatment: pressure therapy can be used, mainly in the form of elastic bandages, pressure suits, pressure pads, and transparent pressure masks customized for facial scarring, etc. Usually, pressure therapy is started within two weeks of wound healing or implantation of skin fragments, and should not be shorter than six months. 2. Medication: In the early stage of hyperplastic scar, silicone gel and allantoin can be used to inhibit the proliferation of scar tissues; in the stable stage of hyperplastic scar, hormonal drugs such as Triamcinolone acetonide can be injected locally into the scar to soften and reduce the size of scar tissues; for some of the traumatic and surgical incisions, Botulinum Toxin A can be injected into the scar after suturing to reduce the tension of the incision in order to improve the scar. 3. Surgery: Scars that are obvious or in a special position that affects the function and appearance can be treated by surgery, and commonly used surgical methods include direct excision and suture, staged excision and suture, keloid contracture release, free skin grafting, flap grafting, and skin soft tissue expansion. It is recommended that patients with the will to treat timely to the regular hospital, under the diagnosis of the doctor, according to the patient’s specific performance, to take targeted treatment, life should be protected from the sun, to avoid mechanical friction and so on.
