Lip flips have minimal side effects and users can pretty much resume their normal day-to-day lives. However, there are still a few recommendations to follow that will help keep the side effects to a minimum and keep you more comfortable. Do not engage in any exercise for the rest of the day following your procedure. The first night after your procedure, you should also avoid sleeping face down. If you notice light bruising or swelling, it is normal. A small bump right where the injection went in is also normal for the hours immediately following the procedure.
