There are a variety of ways to solve you problem. Without seeing photos it is impossible to say if a filler is one of your options. Restylane may be a great option for issues involving the lower lids. Since you didn't notice much of a difference it may very well be that you need more filler. It also may be that a filler was never going to solve your problem and that you needed something else (lower eyelid blepharoplasty, laser of the lower lid skin, better skin care. etc.). For starters, I would hope that your injector took photos before the injections. Often we will inject the lower lids with very good results. Patients will then come back a week or two later, feeling that the results were not as good as they had hoped. The first thing we do is to pull up their pre-injection photos and compare them to photos taken that day. Almost all of the time these people are surprised at how well the injections worked- they had simply forgotten what they looked like before the injections. Give your injectors office a call, set up an appointment to review your before and after photos. You may be surprised at the results. If after looking at the photos you still don't see much of a difference you should have a conversation with them as to why they think that it didn't work as well as you had hoped. Was it because you simply need more, or was it because you really need a different procedure performed. That is where I would start. Good Luck.
