What should I do about my festoons/malar mounds? (Photo)

I am sorry that you have this problem. Fortunately, you do not have festoons which
are bags under the lower eyelids that are caused by swelling that gets trapped
by a ligament that extends from the bone to the skin under the eye. Your problem is more structural in nature and
is called a nasojugal groove. While
normal, your groove is slightly deeper than many and as a result causes a
shadow which makes it look even worse. This
can be filled and there are a number of fillers that will work to improve this
groove. I prefer the long term filler
Bellafill (it used to called Artefill) since it can be placed quite shallow and
therefore the result will be better and longer lasting.

Have added a video about fillers for you here as well as a
web link so that you will have more information.I hope that helps.Best regards.
