If you're a 48 year old male it's highly unlikely you need a full face lift. I haven't seen you so there's no way to know for sure but you are a ways off for the average age of men undergoing the procedure. To answer your question about Botox a qualified doctor will inject conservatively on males. This entails going minimal on the forehead so a horizontal wrinkle or two is still present even after. This results in a refreshed, but not surgical, appearance. You need to be clear with your physician about this and make sure he understands. Many doctors will go overboard injecting even on men resulting in a plastic appearance.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
