Recently I was interviewed by a local new station regarding the new PermaLip implant. See video in the side bar) The PermaLip implant is a soft silicone implant that is placed under local anesthesia in about 30 minutes. The benefits of the PermaLip implant is that it is easy to place, exchange, or remove. It feels soft and once it is placed no further scheduled fillers need to be used.
Other options for achieving fuller lips include using hyaluronic acid fillers (juvederm, restylane, etc), injecting fat, or placing various types of material including fascia, skin, and goretex.
All the procedures have advantages. The PermaLip implant is quick, easy, they look great, and they feel natural. Hyaluronic acid fillers also look and feel great but require priodic injections since the fillers go away. Fat grafting can be a good method to get fuller lips but requires a donor site and some of the fat tends to go away.
The best product or procedure varies for each patient. If temporary fillers give you the look you like than a permanent implant such as the PermaLip or fat grafting is often a good long term choice.
All the best,
