Sculptra® (poly-L-lactic acid) is an FDA-approved biostimulatory injectable designed to restore facial and body volume by stimulating the body’s natural collagen production. Backed by extensive clinical research, Sculptra® offers gradual, long-lasting improvement in skin structure and contour for patients seeking nonsurgical volume restoration. All Sculptra® procedures at Cosmetic Injectables Center Medspa are performed by certified expert injectors under the direct supervision of Dr. Sherly Soleiman.
What Is Poly-L-Lactic Acid (PLLA/Sculptra®)?
Poly-L-Lactic Acid (PLLA), marketed as Sculptra®, is a biodegradable, biocompatible polymer used in medical aesthetic procedures for soft tissue augmentation and facial rejuvenation. Sculptra® acts as a collagen biostimulator, gradually restoring facial and body volume by stimulating the body’s own collagen production. Dr. Sherly Soleiman, MD, a board-certified physician and national trainer in injectables, leads all Sculptra® treatments at Cosmetic Injectables Center Medspa, ensuring optimal safety and natural results.
Mechanism of Action: How Sculptra® Stimulates Collagen
PLLA works by initiating a controlled inflammatory response after injection. Macrophages phagocytose PLLA microparticles, activating fibroblasts and triggering new collagen synthesis. Histological studies demonstrate increased type I and III collagen deposition around PLLA particles, with effects visible from 6 to 24 months post-injection (Wiley, 2024). Porous PLLA microspheres show even faster collagen formation, with deposition beginning as early as two weeks (Frontiers, 2025).
Clinical Efficacy: Facial and Body Volume Restoration
Facial Rejuvenation
Multiple randomized controlled trials (RCTs) confirm Sculptra®’s effectiveness for facial volume loss, wrinkle correction, and skin quality improvement:
- A 2025 multicenter RCT (331 subjects) found Sculptra® achieved a 90.57% improvement in midfacial volume at 12 months, outperforming hyaluronic acid fillers (PMC12273185).
- Another 2024 RCT (260 participants) reported a 67.6% improvement in wrinkle severity at 52 weeks, with over 90% patient satisfaction (PMC12323926).
- Sculptra® is FDA-approved for cheek wrinkles and nasolabial folds, with effects lasting up to 24–36 months (FDA SSED, 2023).
Body Contouring and Non-Facial Applications
Recent studies and regulatory approvals have expanded Sculptra®’s use to body contouring, including:
- Gluteal augmentation (“Sculptra Butt Lift”): Case reports show improved firmness and contour after four sessions, with minimal side effects (ScienceDirect, 2025).
- Arm laxity: Ongoing trials (NCT05445661) are assessing safety and patient satisfaction for upper arm treatments.
- Cellulite and skin laxity: Trials such as NCT04830722 are evaluating Sculptra® for buttocks and thigh cellulite.
For more on body applications, see Sculptra Butt Lift.
Safety Profile and Side Effects
Sculptra® is generally well-tolerated. The most common side effects are mild and transient, including bruising, swelling, and tenderness at the injection site. Nodules or small lumps can occur, particularly if injection technique or reconstitution is suboptimal, but newer formulations and advanced techniques have reduced this risk (Frontiers, 2025). Serious complications are rare when administered by certified expert injectors under medical supervision.
FDA labeling contraindicates use in patients with allergies to any component or a history of keloid formation (FDA Label). Proper patient selection and technique are critical for minimizing risks.
