Botox will take anywhere from 4 days to 2 weeks to start to work. With filler, you should have an immediate result. It may be a case in which you need another syringe of filler. I would suggest going back to your physician and discussing your concerns.
Fillers typically give immediate results depending on which one you had injected. It may take up to 2 weeks to see the results of the Botox. If you are unhappy with only a subtle improvement, I suggest going back to your physician and discussing your unhappiness. Typically, the expectations of treatment are discussed at the consultation and my patients know exactly what to expect from treatment and the results. I always under treat, and if more is needed, we make further improvements at the following visit. I wish you the best, Dr. Emer.
