I want the most for my money being on a budget and want best results, I was wondering which product (Voluma or Restylane Lyft for cheeks) gives best result and lasts the longest?. My doc charges $900 for Voluma and $600 for Restylane Lyft per syringe. Also want to get smile lines done at the appt and wanted to know which is best and last longest Restylane or juvederm ultra? My doc charges $100 less for juvederm ultra. Thanks
