There is a new Juvederm product called Juvederm Volux that has been developed specifically for the chin and jawline. I have not tried it - was considering it as part of my 'camouflage' strategy but decided to opt for jaw surgery / mandible advancement instead. The filler might well be a good (temporary) option for others though, also, it is a low-risk way to see what a more prominent chin would look like on you. I would have gotten it just for that reason alone but now I decided on surgery, it is not a good idea for me because the doctors need to see what I look like without fillers.
