Tear trough filler problems. Is this normal? (Photo)

The photos show a condition that is likely caused by a hyaluronic acid based filler (HA). If this condition is the result of a hyaluronic acid based filler, the solution may be a simple Hyaluronidase injection. Hyaluronidase, an enzyme, is used to remedy the bump by reducing the amount of the (HA) filler in this area. HA fillers should always be used sparingly in this under eye area because they may cause puffiness, but the good news is that an overcorrection can be adjusted with an injection of hyaluronidase.
Most patients can benefit from using other filler types in the area in conjunction with HA fillers, which attract less water and are firmer, to get the best results.  However, injecting other types of fillers in this area is technically difficult and should only be performed by a very experienced injector. Regardless of whether the fillers were applied using a cannula or needle, HA fillers have a propensity to retain water, resulting in a puffy appearance in the under-eye area.  Lasers may be beneficial in reducing the appearance of a bruise but are generally not effective in reducing injectable products such as Hyaluronic Acid fillers. As with all filler injections, it is best to select a dedicated full time cosmetic injector with a lot of experience.

I definitely understand your concern! The bruising at this point can be addressed with a laser to speed up its resolution but will go away on its own very soon. You may want to consider taking Arnica prior to future treatments to avoid such prolonged bruising. The lumps probably won't resolve on their own. You should return to your plastic surgeon and he should be able to address that.As with all cosmetic procedures, especially when it comes to fillers, the skill of the injector is paramount. Always seek an expert in facial aesthetics, such as a board-certified dermatologist, to maximize results while minimizing side effects.
