Alas, fibrofatty tissue seems to melt away in vital areas, such as the lips, face and breast. Even more regrettable, fat seems to accumulate in inconvenient places such as the belly, hips and thighs. Before you decide on a permanent lip implant, I would advise you to try injectables, in order to evaluate whether your injector has the same aesthetic vision as yours. The chief advantage of hyaluronic acid fillers is their temporary nature, so it's unlikely that you'll experience buyer's remorse.
On the other hand, once you have a good working relationship with a Plastic surgeon and are ready to move to a more permanent solution, you might consider either structural fat grafting (injections) or a dermal fat graft because it's replacing what you've lost with a similar material.
I've put Goretex, Alloderm, Tensor fascia and a variety of permanent implants, but these are fraught with complications ranging from exposure to malposition. One of my colleagues in Minnesota commented that the Goretex implants also get very hard and rigid, during winter. So you should be confident that not only will your lips pass the kiss test, but that your speach will not be impaired.
