Sculptra is a specialized collagen-stimulating dermal filler used in aesthetic medicine to address age-related volume loss and restore a more youthful facial appearance. Unlike traditional hyaluronic acid (HA) fillers that provide immediate volume, Sculptra works gradually by stimulating the body’s natural collagen production. Here’s a detailed breakdown:
- Active Ingredient: Poly-L-lactic acid (PLLA), a biocompatible, biodegradable synthetic polymer that has been used in medical devices (e.g., dissolvable sutures) for decades.
- Mechanism: Unlike HA fillers that "fill" wrinkles instantly, Sculptra acts as a collagen stimulator. It triggers a controlled inflammatory response, encouraging fibroblasts to produce new collagen over time. This process gradually restores facial volume and improves skin texture.
- FDA-Approved: Primarily for treating facial fat loss (lipoatrophy) in areas like the cheeks, temples, and nasolabial folds. It’s also used "off-label" for hands, jawline contouring, and other areas.
