Hi,At my practice I recommend our patients wait a week after injections with fillers like Juvederm, Voluma, Radiesse or Restylane to do their micro needling. Though these dermal fillers go deeper than the fine needles of the micro needle it is always a safe bet to wait. After the micro needling itself the skin is slightly swollen and irritated which makes it a little more challenging to inject fillers. If a patient is on a time crunch or isn't getting an aggressive treatment with the micro needling then I have some flexibility in my approach and can make an exception and do both. These two modalities partner very well together to improve tightening, tone and texture of the skin above and below the surface.As always, I recommend an in-person consultation.
