Brow lift can be a great way to improve the shape of your eyebrows, but there are certain hazards and side effects. For example, formation of hematoma, wound infection, scar proliferation, and asymmetry of eyebrows on both sides. 1. Formation of hematoma: When brow lift surgery is performed, the local skin needs to be cut, which will cause subcutaneous capillary rupture and bleeding. If the amount of bleeding is relatively large, a local hematoma may be formed. 2. Wound infection: after eyebrow lift surgery, if the wound is not sterilized in time during the recovery period, it is easy for the wound to become infected. 3. Scar hyperplasia: After brow lift surgery, a certain amount of scarring will form after the wound heals, resulting in the phenomenon of scar hyperplasia. 4. Eyebrow asymmetry: If you don’t pay attention to maintaining the balance between the two sides of the eyebrow lift, it is easy to produce the phenomenon of asymmetry between the two sides of the eyebrow, which will have a certain impact on the appearance. It is recommended to choose a regular hospital for the surgery to reduce the risk of surgery.
