Generally, scar patches can be applied after the incision after thyroid surgery is completely healed, and the incision on the neck can be healed in 4-5 days after surgery without infection. Scar patch is a relatively advanced scar removal supplement with the effect of inhibiting scar proliferation and softening scars, which can be used for the treatment of scars formed by burns and surgical incisions on the body surface. Patients should first ensure complete wound healing in the process of use. Due to the rich blood flow in the head and neck area, the healing of thyroid surgery incisions is relatively fast, usually 4-5 days, at this time, if there are no signs of infection such as redness, swelling, pain and hard nodes at the incision, you can use the scar patch. If there are signs of infection or other abnormalities, the scar should be treated first, and scar patches should not be used directly. In addition, in addition to scar patches, there are also laser treatments to remove scars, and the specific plan should be chosen according to the type and location of the scars.
