Maley,
This may be a result of initial undercorrection by your physician as 3 months is a short duration for improvement. Regardless, patient's are ultimately in control of when to have a second injection based on the satisfaction with the overall results. I would recommend that on your second round of treatment ensure that enough product is used to obtain a complete correction of all your areas of concern. It may provoke a slightly higher cost in the short term but will provide you longer more stable results. With an experienced injector, the presence of preexisting filler should not alter your ability to have a nice result on the second go around.
