A brow lift can help improve wrinkles in the forehead, the brow and the area around the eyes by raising the soft tissue and skin of the forehead and brow. It can help with sagging brow or brow asymmetry. A brow lift can be done using face threads and can be done on its own or also with a combination of eyelid surgery. Lower eyelid surgery works by removing excess skin and fat and sewing the skin under the eye back together, giving the undereye area a tighter appearance.
