Sculptra works differently than most other dermal fillers. Instead of the material in the syringe creating the aesthetic improvement, Sculptra induces new collagen production which leads to the volume enhancement. A very frequent question for patients is; what happens to this new collagen?
The answer is a bit complex. The body does not 'see' this new collagen as different than the collagen that existed prior to Sculptra treatment. What does change is the balance of repair and degradation. There is a constant process of creation of new collagen and breakdown of existing collagen occurring daily. For most people, somewhere in their mid 20's, this balance shifts towards more degradation and they start to see volume loss. But here's the lousy thing, the more volume loss you have, the more the balance shifts towards degradation. Think of it like this; once the process heads down hill, it picks up speed.
The whole process slows when you add a filler. The added volume shifts this balance back towards the creation of new collagen. The more volume that is added, the more it slows the degradation process. Why this is important when we talk about the effects of Sculptra is that the closer you get to full correction of the volume loss, the longer the effects of the Sculptra will last. So, the effect of two vials of Sculptra will last more than twice as long as the effect of one vial, the effect of four vials will last more than twice as long as two. As I said, the answer is a bit complex. The bottom line: for the longest lasting results, it is best to aim for a full correction right from the start.
