That's a great question!It's something that's being looked at for the future in order to avoid injections into the blood vessels within the muscle. Please always consult with a board certified plastic surgeon.All the best,Moises Salama MD, board certified plastic surgeon
Thank you for the question. To minimize the complications new guidelines have been issued. One of the recommendations is to inject only in subcutaneously using larger cannula. US can be used however person injecting has to be trained. It is best to consult with a a board certified plastic surgeon. Good luck.
