Lines and wrinkles around the mouth area are challenging and, like Dr. Chen stated, combination treatments often are the best option. The mouth muscle is quite strong and works in a purse string fashion - pulls in and downward. Some practitioners will inject the vermillion border (where the white meets the pink of the liips) to smooth out small, vertical lines around the mouth. Some lines extend too far from this border for this technique to be of any value. We use other techniques with cosmetic dermal fillers to address this problem in addition to small amounts of Botox or Dysport.
Regardless of the above, we believe the bigger issue here is that you were not kept involved in the treatment plan or were not proactive in voicing your goals and concerns at the time of the visit. In our practice, all patients are photographed prior to the treatment. You may want to ask to see these photos (if they were taken) or find a photo of yourself that you may use as a comparison. Being that you are still bruised, it may be too soon to judge the final outcome. In any event, I would encourage you to express all of these concerns with your practitioner without further delay. A good practice would not want to lose you as a patient if there was a way to remedy the situation.
