What is aspiration?
This is only relevant for dermal fillers rather than Botox and refers to fixing our needle in the position we are about to inject, pulling back on the plunger of the syringe and ensuring no blood has pulled back into the syringe. If there is blood, this would imply that we might be in a blood vessel and hence not safe to inject.
But a negative aspiration doesn’t always mean that you are safe . Know your anatomy first .
