How long before an overfilled tear trough (with restylane) start to look not overfilled?

Restylane can last an average of 6-8 months, and it generally lasts longer in the tear trough. The filler will disappear on its own over time, and it can take up to one year for the filler to disappear in this particular area. When performed properly by a skilled expert, hyaluronidase injections can successfully dissolve any unwanted filler that is present. I would recommend following up with your injector and discussing this option with him or her. I hope this helps, and I wish you the best of luck.      

Restylane can last years in the under eye area. If you feel you are overfilled, the best option is to dissolve the filler with hyaluronidase and start again. If you are really lucky, putting in a small amount of diluted hylaluronidase may solve the problem completely. However, the most likely scenario is that most of the Restylane will go away and you will need an additional treatment.

Hyaluronic acid fillers tend to last longer when injected to the tear troughs because of less movement, typically 12-16 months. I suggest you consult with your provider and ask if he/she recommends massaging the area
