After my facelifts patients have told me that they look 20 years younger. But, they were older than 50.
Most look 10-15 years younger with the benefit of surgery and skin rejuvenation. You want to look healthier, younger and better than before surgery but it's unrealistic to think that you can look like a 30 year-old. The appearance of your hands and skin will probably be a give away of age.
