Is lip augmentation via fat grafting permanent?

I would advise patients contemplating lip augmentation to start with Restylane or Juvederm. More importantly, the method of treatment is essential. I prefer the French Method for lip augmentation that increases vertical lip length. Best, Dr. Karamanoukian

Fat transfer is a great treatment that can be used in a variety of ways.  Fat has become a vital part of facial rejuvenation.  I use fat in almost every facelift or eyelid surgery that I do because of the natural and youthful appearance that it can add to the results of your surgery. 
Lip augmentation has become very popular over the past few years.  When lip augmentations are done correctly they can add a very youthful, attractive appearance to the face.  One of the common complaints of lip injections is that they tend to go away faster then patients would like. 

Fat is a great alternative to fillers as it is going to last much longer.  The benefit of the fat is that it is going to last for years to come rather than the six to nine months that the majority of fillers last. 

I would not say that they will replace fillers as fillers and fat all have their place. Fillers are a great start for patients so that they can get feel for the rejuvenation that they can expect from adding volume.  Also fillers are a great quick fix as they can be done in the office in as little as ten minutes. 

Fat grafting give patients more options if they want a more long-term solution or I have many patients that like fat because it is natural and from their own body. 

I hope this helps, please consult your Board Certified Plastic Surgeon.
