Avoid the bridge and entire nose, between the eyebrows, forehead and nasolabial folds for facial fillers; never choose unregulated injections to save money.
Of the people who went blind after a filler injection, more than half were injected in the nose, and next came the area between the eyebrows, the forehead, and the folds beside the mouth. More than 8 in 10 were given hyaluronic acid. Of the people who went blind, only 2 in 10 got their sight fully back, a bit more than 1 in 10 got part of it back, and nearly 2 in 10 also had damage to the brain. No rescue method works reliably right now, so avoid these sites beforehand.

No cost at all. You simply choose a different injection site, or skip the treatment altogether.
Data compiled from all published case reports worldwide show that from January 2015 through September 2018, 48 new instances of partial or complete vision loss occurred after filler injections. The nasal region accounted for 56.3% of incidents, followed by the glabellar area at 27.1%, the forehead at 18.8%, and the nasolabial fold at 14.6%. Hyaluronic acid was identified as the filler material in 81.3% of cases. Skin changes appeared in 43.8% of patients, while central nervous system complications arose in 18.8%. Ten patients (20.8%) fully recovered vision, eight (16.7%) partially recovered, and the remainder did not improve. Researchers concluded that treatment approaches varied widely across studies, and no single method has been demonstrated to reliably restore vision.

Open source linkThese figures were counted case by case from cases reported in journals. They include only the people who had the event, not the total number of people injected. So you cannot calculate how likely 1 injection is to cause blindness. You can only see which sites have more events, and that afterward it basically cannot be reversed. The evidence is graded B for this reason too. What a regular institution does to lower the risk is already routine. First map how the blood vessels run under the place to be injected. Use a blunt needle rather than a sharp one. Push a small amount while withdrawing the needle. Have hyaluronidase (the enzyme that breaks down hyaluronic acid) ready beforehand. Each of these requires that the person doing it is a trained doctor. That is also the reason not to use an irregular channel. Before you do it, check it against item 2 of this section (check the facility license and the attending physician).
