The results of an endoscopic eyebrow lift are designed to last for many years. This is because the procedure helps to tighten and strengthen the underlying tissue of the brow. Additionally, because the muscles that control frowning are released during this procedure, it can also help reduce the depth of vertical frown lines. However, like any other cosmetic surgery, individual results may vary, and it is always best to maintain a healthy lifestyle and use sun protection measures to preserve your results for as long as possible.
