Had Botox and Radiesse 4 days before CT scan. Would the radiation from the scan affect my results or how long the filler lasts?

no fillres will not ruin your CT scan results although they may show up on them if the scan is done in the area you were treated. Best, Dr. Emer.

Thanks for. CT and ionizing radition scan should have no effect on your cosmetic filler treatments. I hope this helps reassure you.  

Thanks for your question. CT scan should have zero effect on your cosmetic treatments. Thanks for asking and warm regards.

CT scan radiation has no biological effects on Botulinum toxins (Botox).
Radiesse filler is a biostimulant dermal filler that consist of calcium hydroxyapatite which can be seen with CT imaging, however there is no evidence to support ionizing effects of the minuscule fleeting radiation from one time CT scanning. 
You do not need to be concerned about the immediate or longer term effects of CT radiation to your Botox or  Radiesse filler injections. 

It's highly unlikely that the small amount of radiation would affect how those 2 products work.Best of luck to you.

The CT scan will not affect how long your filler or botox lasts.  The Radiesse may show up on an Xray as it made in part by bone, Calcium.
