How long does fat transfer to lips last?

Fat is a great option if you want permanent. You can overcorrect at first and some will dissolve. I like Fillers better because you can get exactly what you want.

Good question, as a lot of confusion exists about this subject. For longer term results, fat transfer is your best option because research suggests that 1/3 of fat transferred becomes permanent. That percentage may be lower in the lips because of the constant motion of that part of the body. Juvederm is another option, but lasts only 2-4 months in the lips, making it expensive for a long term option.

It is hard to predict how long fat will last in the lips.  For some people the fat to the lips does not last as long as it does to other areas of the face.  This may be due to the large amount of movement in the area.  The same goes for the other fillers.  Some of the fat will always resorb.  What remains after a few months should last a long time.
