The ask in one line
This page gives no duration. Ask the clinic what it expects for your case and what it bases that on.
What to pin down
A duration claim is only useful if it says what is being measured. Ask for that.
- Ask what outcome the duration refers to.
- Ask how the clinic checks that outcome over time.
- Ask what a follow-up or repeat treatment would involve.
- Ask what the clinic does if the result fades sooner than quoted.

Where to read more
For research background, start with a laboratory study of poly-L-lactic acid particles and collagen synthesis. Then read a multicenter retrospective study on the safety of immediately reconstituted poly-L-lactic acid. Check each paper for what it measured and for how long, then compare that with what the clinic quotes.
Closing directive
Treat any duration as an estimate until the provider explains how it was reached. This page comes from a site that reads research rather than treating patients, so it is not medical advice.
