Does filler actually dissolve over time or does it migrate to different areas of the face?

Fillers should not migrate. It’s very important to have a credentialed injector who is board certified in plastic surgery or dermatology and who purchases product from the manufacturer, and not gray market goods.   it is well known that silicone can migrate, among other havoc, and this is not FDA approved for cosmetic use.

Hi,There is evidence that hyaluronic acid fillers "light up" on MRI imaging. It is important to remember that this does not necessarily mean that they can be obviously seen in real life. Fillers can migrate a short distance in areas such as the lips and under eyes and that is why not manipulating them or massaging the treated area is important. I am not sure there is any utility in dissolving fillers (except lip and under eyes) past a couple years post-treatment.Best,

Fillers which are FDA-approved and are injected using a proper technique buy a plastic surgeon who is trained in such procedures should not move in any way, shape or form. The only area on the face where a small amount of movement can be seen with some fillers is in the lower eyelid area. I hope this helps and good luck from New York City plastic surgery
