And if so how much of a difference did it make? I'm getting really deep lines at the corners of my mouth (possibly the start of nose to mouth lines although one looks like it might dart off in another direction entirely) and they're really bothering me. Just wondering what sort of a difference filler would make or if there are any alternatives? Is it true that ultherapy can't be used too near the mouth or have I got that wrong? It did wonders on what looked to be a really deep smile line that was developing in the middle of my cheek.
