Why do my tear trough fillers not last more than 6 weeks?

This is difficult to determine, but some people do metabolize filler faster than others. A permanent solution to eye bags is lower blepharoplasty.  The results should last about eight to ten years. You should also develop an anti-aging regimen with your facial plastic surgeon that will include skin care and laser treatments to maintain the results of your blepharoplasty and keep your skin looking healthy and young as you age. I hope this helps.

I'm not sure why your filler did not last. Some people do have a higher metabolism, but I'm wondering if you just had an undercorrection. I suggest you get a second opinion and consider a different filler. The most reliable filler in our practice for the tear trough has always been Restylane. I would also suggest a cannula technique for better placement into the groove.Good luck. Dr. ALDO 

I love Juvederm. But, Juvederm is my least favorite HA filler for the tear trough area, mainly because of its well-deserved, notorious reputation for delayed and persistent swelling. All HA fillers last around a year in this less mobile area. Your history is quite unusual, so I would seek a second opinion, optimally with an oculoplastic surgeon.
