Do all under eye fillers result in complications?

Under eye fillers, when done correctly by a skilled professional, can provide excellent results for many years. However, it's true that they can sometimes lead to complications such as migration, malar bags, puffiness, edemas, and festoons. These potential side effects are not a guaranteed outcome for everyone, but they are possibilities.
The risk of these complications can be minimized by choosing an experienced injector, using the appropriate type of filler, and injecting the correct amount. Additionally, maintaining regular follow-up appointments with your provider can help monitor the longevity and potential migration of the fillers.
As for dissolving fillers, the process can be more challenging the longer the fillers have been in place, especially if they have migrated or caused other complications. Hyaluronic acid fillers can be dissolved with hyaluronidase, an enzyme that breaks down hyaluronic acid. However, this process may be more difficult if the fillers have been in place for a long time or if they have migrated significantly.
Keep in mind that everyone's body reacts differently to fillers, and individual results can vary. It's always best to discuss your concerns with a qualified professional who can provide guidance based on your specific situation.

Undereye filling is tricky. Less is more in almost all cases. I suggest injecting deeper and using a finer filler like Volbella. Hyaluronic acid fillers are best as they can be dissolved.

They don’t. It can be harder to dissolve in some instances but usually it is removed successfully in one or two sessions - it you inject the hyaluronidase at the right place.

Under eye fillers do not always end up problematic. Many patients have used them for years and remain happy with their results. It is important to select an experienced injector for your treatment and to use medical grade skin care products for the sensitive eye area.

That's an Incorrect assumption. They don't. Everything you do carries some potential risk and complications. Undereye filler is the most complex injection, therefore it should only be done by highly trained physicians and they should not only know how to inject but how to manage any unwanted side effects.
I have been able to dissolve a 10 year old filler for some people coming to my practice. HA fillers can last a long time and they can safely and effectively be dissolved. Many practices are beginning to adapt Ultrasound into their practice and if you want to have it fully dissolved, then confirmation with an ultrasound or Ultrasound assisted dissolving is a the best way to go about it. As there is an art of injection, there is an art of dissolving.

I would agree with your statement, and I’ve been saying this for the last two decades and more. Hyaluronic acid fillers in the lower eyelid simply do not belong. The thinner the individual the more problems. Hyaluronic acid fillers, are two gelatinous and react to the surrounding muscle forces by becoming displaced creating lower eyelid bags and associated Tyndall effect. The best treatment is prevention. That means do not inject to hyaluronic acid filler, and forget hyaluronidase. But in individuals who have received hyaluronic acid, fillers, hyaluronidase has to be used to treat a bad outcome. In my opinion (30 years), fat grafting works absolutely the best in the lower eyelid area, producing natural and permanent results. I hope this helps and good luck from New York City Plastic Surgery.
