I want HA fillers to lift my nose tip, under columela... I'd like to know with filler is best and lasts longer in that area... and how much for that area ONLY? I also would like to know if it is possible to make a formation on that... I mean learn how to do it (on that area only) so I can, one day, spare a trip to the doctors office and do it to myself... how much do those fillers cost for you dermatologists and P.Surgeons?
