Sculptra is an injectable biostimulatory filler composed of poly-L-lactic acid (PLLA).
This synthetic, biocompatible, and biodegradable substance has been safely used in medical applications for decades, including in dissolvable stitches and soft tissue implants.
What sets PLLA apart from traditional hyaluronic acid (HA) fillers is that it doesn’t just “fill” space—it works by stimulating your body’s natural collagen production to rebuild the skin’s structural support gradually.
Once injected into the deeper layers of the dermis, PLLA microparticles are slowly absorbed by the body, activating fibroblasts to create new collagen over time. This process helps improve skin thickness, elasticity, and volume, particularly in areas affected by age-related volume loss, such as:
- Hollow temples
- Sunken cheeks
- Jawline laxity
- Nasolabial folds
Because the improvement develops gradually over several weeks to months, Sculptra offers subtle, natural-looking rejuvenation that strengthens and thickens the skin from within. While mild swelling after injection may create a temporary “preview” of results, the true benefit unfolds as your skin regenerates and rebuilds its underlying support network.
