What I try to do is to make your face look like it did when you were younger. I always tell people it's not just about filling in the lines, but re-creating the shape of your face as it was in your early- or mid-twenties. People see the lines as they age but they don't see how their shape is changing. I think it's all about restoring the contours. You can fill in a line and it makes you look a little better, but it doesn't make you look younger.
