“Nose jobs and permanent fillers: need advice”

Seeking help:

Hi. im italian. Many years ago i had a rinoplastic, then another after 7 years. Now after other 10 years half of my tip is empty. That's not a huge thing but you can see it. i was suggested to use some fillers to correct this imperfection. i red on line that the permanent filler, very used in italy - Bioalcamyd and the others are requested to be take away from the market because of high risks of complicances. I know that the FDA has accepeted just 7 permanent fillers. So i really would need an advice, the more possible honest. Thank you very much. Lara
