Hi I am female mid 50s with just a touch of laxity in face and neck, would like to try sculptra but spent a long time struggling with overfullness from facial fat transfer. I have asked the practitioner to do one vial at a time so we can proceed really slowly but her advice is that it won’t do anything that way. Does going lightly like this actually prevent the process working properly in the long run or just slow it down (which is my goal)? Many thanks!
