Summary

This pilot study investigates whether injections of Poly-L-Lactic acid (PLLA), a collagen-stimulating substance, can safely improve skin laxity and wrinkles on the neck. Ten adults aged 30-60 with mild to severe neck skin looseness will receive a single treatment session. Researchers will assess changes using clinical photos and a standardized scale over 24 weeks, along with participant satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Poly-L-Lactic Acid (Sculptra) injection
What this could lead to: If effective, PLLA injections could offer a non-surgical option to tighten loose neck skin and reduce wrinkles.
What could go wrong: This is a very small pilot study with only 10 participants, so results may not apply broadly. The treatment may not work or could cause side effects like swelling or bruising.
