Fat grafting or dermal filler to the lip
The main issue with your upper lips is that it lacks volume. There are a couple ways to address this. One is with the use of dermal fillers, such as Restylane or Juvederm. These contain hyaluronic acid which naturally volumizes the area it is injected. This is temporary and lasts about 9-12 months. The other option is structural fat grafting where fat is taken from either the abdomen, thigh, or buttock and placed within the lip. This can provide a potentially longer lasting result. Both area reasonable options but the dermal filler has less of a recovery associated with it. Hope this helps!
