I'm 37, male from Los Angeles, thin and athletic, but I have a second chin and a weak jawline. Would filler help? (Photo)

 In addition to your weak chin you have depressions and volume loss over your cheeks. This can be filled with Voluma or cheek implants.  A chin implant with submental liposuction will give you very nice results that you were looking for.

I suggest you go to a facial contouring expert who specializes in fillers and fat transfer for male facial defining. Cannula injections limit side effects and give meticulous contouring. I have patients travel from all over the world for this. Do not compromise your care for cost or distance. Best, Dr. Emer.

If you want to have a more defined jawline, you need can have some liposuction under the chin, and add some Juvederm Voluma along the jawline, to enhance that area. The results from Voluma are natural and usually last for about 18 months.

Yes, fillers are actually a great option to smooth the jaw line. The fillers can last about 2 years with effective result.

The good news is that you have a lot of options! You can certainly inject filler to your chin to make it more pronounced. This will last about a year or so before you will need more filler, depending on the type of filler used. You may want to explore the new Kybella, which melts fat via injection of medication to your "double chin". There is temporary swelling that comes with this, but the results should be fairly permanent. The other non-surgical option for you that I would suggest is Ultherapy, which we can use to not only melt the fatty tissue under your chin, but also tighten skin and soft tissue virtually anywhere. See a board certified plastic surgeon or dermatologist for an in person consultation and advice.
