I was told by my doctor in Australia that there is quite a high risk of infection with the artificial fillers for marionette lines, can one use fat transfer as successfully as the artificial fillers?? The other reason I am asking is that I have tried HA products under the eyes and my body absorbs the HA within three weeks. So this makes me wonder if the artificial thicker fillers like Perlane might be absorbed quickly as well? I am trying to avoid lumpiness from fat transfer. Thanks.
