I had 4 syringes of voluma injected in my cheeks 2 weeks ago. I don't notice any changes. None at all. Did it work?

Thank you for your question. It is not common to experience zero results after 4 syringes of Voluma to your cheeks. Perhaps consider scheduling a follow up with your injector to assess before and after photos. Best,

This is an impossible question to answer without the benefit of pictures and an evaluation.  Both Sculptra and Voluma are excellent products for adding facial volume.  The amount of Sculptra and/or Voluma required would depend on the extent of facial volume depletion at the outset.  The difference in reaction to these products is that Sculptra provides a delayed volumizing effect, whereas Voluma is immediate.  The efficacy studies for Voluma in the Unites States are based on a 6 syringe model. These are both very technique dependent products, but further comments cannot be made without more information.

It would be unusual not to notice a difference with 4 syringes of Voluma.  I think your best option would be to go back to the doctor that did the injections and compare your before photos.  Sometimes we forget exactly how we looked before a procedure.
