I was taught the art of using Silikon-1000 to correct nasal irregularities during my fellowship. When used properly, you can safely get completely natural, permanent results. Since Silikon-1000 is a permanent filler, your results depend entirely on the technique, and expertise of your physician. You should consult a board-certified dermatologist or facial plastic surgeon experienced in the micro-droplet technique. You should see many photos before proceeding. Microdroplet Silikon-1000 works particularly well for permanent nonsurgical nose job treatments. Several treatments are typically necessary for achieving a permanent desired result. There is no risk of blood vessel occlusion or blindness. I've attached a link to my Non-Surgical Rhinoplasty gallery page for your perusal. I hope this is helpful, and best regards.
