Permanent Filler (Artecoll) for Nose or Forehead?

I came across mention of a *permanent* filler named Artecoll that's sometimes used in Korea (not sure if it's FDA approved in the USA) for augmenting the nose and forehead.

I'd be curious to hear if anyone has had experienced with permanent fillers, since it sounds like it could be a potentially less invasive / less risky(?) alternative to full blown surgery, forehead implants, etc.

Has anyone heard of or used this before?
