Is this malar bag on the right side? (photos)

Dear Sampa71,It appears you have festoons/ malar mounds which are being exacerbated by the filler in the lower lid region. Best option would be dissolve the filler first and then assess the condition of the festoon/ malar mound. Then if they are still present, there are treatment options available. I've had success using lasers to tighten the skin causing lower eyelid festoons and malar mounds.I'll include a link below.I hope this was helpful. 

Everyone has some asymmetries. Under eye bags can be permanently corrected with surgery or temporarily camouflaged with fillers (Restylane, Belotero, Volbella).There are great non-surgical options to fill in under eye depressions and hollowness. Using dermal fillers, a liquid eye-lift can be performed. A dermal filler such as Restylane would be placed in the cheek and tear trough to hide the depression or bag underneath your eye.
Surgery would require a fat-repositioning lower lid blepharoplasty. In this surgical procedure, fat from the eye area is moved into the tear trough depression filling the actual depression. 
I hope this helps!

It is a little difficult to tell from the photo, but it looks like you may have some swelling of a malar bag on the right side.  I would recommend having the filler dissolved (with hyaluronidase) and then starting over.  Because fillers absorb water, they have a tendency to make malar bags worse in some patients.  

A combination approach will give the most improvement. Fillers, lasers, and microneedling/PRP can improve under the eyes. My patients try to get non surgical treatments to avoid surgery. We use PRP and stem cells there often. I suggest consulting with an expert to develop a treatment plan best suited for your short and long term goals. Best, Dr. Emer
