Lumpy temple filler results and now I have dents, should I ask for filler with a blunt canulla?

Facial fillers using Hyaluronic acid can cause immediate swelling and uneven contour. The swelling usually subsides with time. I recommend applying Plato's Bruise Balm twice daily for a few days after injecting my patients. If the filler lumps do not resolve, then a small injection of Hylenex usually can correct an HA filler that is overdone. If Hylenex does not work, combination injections with verapamil or corticosteroid IIT may help. 
In some cases, Venus Viva RF can help tighten skin thereafter.

It takes 1-2 weeks for final results of fillers. If you were injected with an HA filler and you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. Cannulas will limit complications. Sculptra is an alternative for the temples. See an expert. Best, Dr. Emer

Hi Sarah,  it would be helpful to know what type of filler was used for your temples.  HA fillers will even out in 2-4 weeks. But if you had Radiesse or Sculptra, it would be quite a while before those bumps go away and you might need to go back to your provider for a follow up.  Cannula technique is much more  comfortable for the patient and allows even and deeper deposition of the product. Hope this helps. Best,Dr.Avaliani

Because you are most likely experiencing residual swelling, 10 days is premature to determine the quality of your results. Cannulas are used to improve the safety of the treatment, but do not necessarily improve the smoothness of the results. If the filler was a hyaluronic acid based filler, such as Restylane or Juvederm, then you may benefit from an injection of Hyaluronidase, an enzyme which can reduce some of the filler lumps that are the most pronounced.    
Regardless, you should wait at least 2 to 3 weeks  before determining the quality of your results. You should follow-up with the physician who administered the treatment you are referring to.

It usually takes 2-4 weeks for the lumps to smooth out if a HA filler was used, longer for Sculptra or Radiesse. The use of a cannula vs a needle doesn't make a difference in regards to smoothness. I would give it some time and if the irregularities remain you can consider dissolving it with hyaluronidase if a HA filler was used. Good luck!
