What does the research say about Sculptra and PLLA biostimulators?

What question did the researchers ask?

The authors reviewed randomised trials of injectable poly-L-lactic acid for facial ageing or facial lipoatrophy and formally assessed risk of bias.

What did they actually find?

Several trials reported greater dermal thickness, improved lipoatrophy or aesthetic scores, and effects maintained for at least 25 months. Reported adverse effects were mostly mild or moderate, including bruising, tenderness, swelling and nodules.

What should you keep in mind?

Five of the eleven trials were judged at high risk of bias, so the review rated the overall evidence as low quality. Durability and safety still depend on indication, dilution, placement, course and follow-up.

What does this mean for a Highfield consultation?

The review found promising outcomes but low-quality evidence and called for better controlled studies. We consider that finding alongside independent guidance, your medical history, examination and priorities. It can support a better-informed decision, but it cannot promise a personal result or decide whether treatment is suitable.
