I have very small/thin lips. It's my biggest insecurity and affecting my self esteem. Could fat grafting help me? (Photo)

I would highly recommend getting a formal evaluation with and treatment from a board-certified cosmetic dermatologist and expert in facial sculpting. Technique is the key to a successful lip augmentation with fillers, so you'll want to see someone meticulous. An experienced physician will be able to determine which filler, how much filler, and which technique will give you the subtle result you're looking for. See an expert. Best, Dr. Emer

Dear twosidesofme,
I perform a lot of lip injections with fillers such as juvederm and it works great. Many times I need to put more in one side than the other to attempt to even out the vermillion border (The red line of the lip). This helps provide more symmetry at times.For patients looking for a more long lasting result, I recommend fat grafting. That is, using your own bodies fat to make your lips naturally look more shapely. The bonus is that the results last many many years.
In general, I avoid using permanent prosthesis because I find that the lips are such dynamic and sensitive structures, the end result is not natural.

Fat transfer to lips seems like a good idea
My Q's: 1) What are the chances of the fat in my lips dissolving unevenly? Very unlikely
2) Would my lips look saggy because fat is heavy? No
3) how much bigger/smaller would my lips get I put on or lost weight? There could be some changes but aren’t as dramatic as you may think
4) would I get the duck lips look as with the hyaluronic fillers? If done properly No

Having fillers is a safe and non-surgical option you could do. It will add volume to your lips while still having that natural and plump look. Visit a trusted practitioner to know more about the procedure.
