Sculptra is a cosmetic injectable treatment designed to stimulate collagen production within the skin. Unlike fillers that provide immediate volume, it works gradually by prompting the body to generate its own natural collagen. The active ingredient, poly-L-lactic acid (PLLA), is a biocompatible synthetic substance that has been used in medical applications for many years. Its mechanism of action involves triggering an inflammatory response, which in turn stimulates fibroblasts to produce new collagen fibers.
The delayed onset of visible results is a defining characteristic of this treatment. While some initial plumping may be observed due to the injection itself, this effect is temporary. The true benefit lies in the gradual improvement in skin texture, volume, and firmness that emerges over time. The stimulation of collagen helps to restore a more youthful appearance by addressing underlying structural support of the skin. This approach offers a more natural-looking outcome compared to immediate volumization with traditional fillers.
