To answer your question, the risk is so low that if the injections are preformed by a qualified MD there should be no issue. With that being said, can the risk of an embolism occur with injectables? As we are taught in residency training and medical school, "Never say never!"
The rule of thumb is to have a qualified MD (A boarded Plastic surgeon or Dermatologist).
Slow injection and withdrawal techniques.
A good medical history, especially if use of blood thinners or poor clotting.
If still fearful, do a test area with the injectable. To see the results and effects.
I agree with my colleague, Dr Rohrich, as to areas and differing types of fillers to use. It is best to have choices and recommendations from the treating doctor to which filler might be better for each area.
Hope this helps!
