Is hyaluronic acid injection between eyebrows (glabella) dangerous?

The director of our clinic came to Japan from the United States back in 2005. Just ten years ago I gave a lecture on safe hyaluronic acid therapy etc. to the doctors as a lecturer at a seminar on beauty care procedures such as hyaluronic acid. At that time, there was a report that there was already high risk of injection of hyaluronic acid-containing injections into the surroundings of the eyebrows in the United States.

There are few small arteries that are dominant in the vicinity of the eyebrows, and there is no supply of blood flow from the other side with side chains to each other (the end- artery). When injected material enters such a blood vessel, surrounding tissues die (necrosis). Also, since the artery around the eyebrows is located close to the arteriovenous of the orbit (in the dent of the eye), multiple examples in which the injected substance enters the eye artery for reflux to cause blindness It has been reported.

In the case of hyaluronic acid, there is still an enzyme agent that dissolves it, but there are cases where it can not be saved with other injectables, especially those of semi-permanent type.

The same problem may actually occur not only in the glabellar region but also anywhere in the center of the face. There are several technical key points when injecting subcutaneous infusions such as hyaluronic acid, and for those who do not master it, these risks are even higher.

In general terms, I think that treatment of these subcutaneous infusions should be done by specialists (board-certified dermatologists or plastic surgeons) who are familiar with cosmetic medicine (also attending academic societies) doctors. At our clinic, we explain the possible dangers to patients when treating that part, and we are doing the treatment.
