Am I a good candidate for lip injections, or am I at risk of having "duck lips" due to having slightly fuller lips? (photo)

Is it possible to get some tweaking of your lip with filler but the vast majority of injectors you are likely to see are not going to be able to achieve the result you require.  To understand why this is the case, please understand that doctors go to medical school not art school.  They lack the sculpting skills that are needed to really understand what you are looking for.  Commonly, they will also use the wrong tools.  Generally, hyaluronic acid fillers come it two varieties: Not runny and runny.  Technically these are high G prime, low tan delta fillers versus low G prime, high tan delta fillers.  Don't even consider anything but a hyaluronic acid filler.  The hyaluronic acid fillers can be dissolved if there is ever a problem with then.  The runny fillers like juvederm, belotero, or restylane silk, do not stay where they are placed.  As a result they are not sufficiently precise to accomplish your goals.  The non-runny fillers include Restylane and Lyft.  Lyft is too stiff for the lip.  Restylane is your product.  Try not to harm yourself out there.  I do not really think you need lip fillers.  Your lips are rock'n.

Hi @em93x. Technique and product choice is everything! I recommend seeking treatments from expert injectors who have the skill and experience to precisely inject fillers into treatment areas and avoid risks and complications. Best of luck, Dr. Nima!

Thanks for your question. Strategically placed filler, containing hyaluronic acids such as Juvederm, Restylane, and Volbella, can create fuller volume in the lips. Indeed, it can even suddenly change the shape of the lip as well. However, if you have significant lip shape issues, such as a long upper lip or drooping corners, then you could opt additionally for other procedures, such as an upper and/or corner lip lift. Best to consult with a board certified plastic surgeon who specializes in lip augmentation.

 I think you would do well with a little filler in the lips in specific spots and it shouldn't make you look duck like at all.

You would get a nice improvement with lip fillers (Volbella, Restylane, Juvederm). You'll want to see someone meticulous. Nova threads can be used to improve lift and shape. Implants or fat are alternatives. I recommend getting a formal evaluation with a facial sculpting expert to go over your desired results. Best, Dr. Emer

Dear em93x,I typically use Juvederm for my lip sculpting. There are two main focuses of lip injections, adding volume and actually sculpting the shape. Both involve injecting the filler in different areas of the lips and patterns.
I would recommend finding a plastic surgeon to perform you lip injections. Most of my patients have results that last at least 6 months.Daniel Barrett, MD, MHA, MS

Lip size and shape are highly personal choices. Please consult a board certified aesthetic dermatologist for a consultation.  

Your lips have good size. If you want them more augmented then it is possible to do so with fillers. You have to be conservative so they are not too large. I use a microinjection technique that gives natural results without the ducky appearance. Best wishes.
