How it is given
Poly-L-Lactic Acid is not applied as a skincare step. This is what the record says about how it is administered.
This is not a step in a skincare routine. It is a professional procedure. Nothing here is a recommendation to have it.
Is this safe for me
Everything the record says about suitability, consolidated. Pause-first comes first.
Pause first
- active skin infection
- acute inflammation
- history of keloid scarring
- autoimmune connective tissue disease
Pause means check first, not never.
Before you start
Requires precise clinical reconstitution and sub-dermal injection technique by trained medical professionals. Post-injection massage is required to prevent the formation of subcutaneous papules or non-inflammatory nodules.
Pregnancy and breastfeeding
Not medical advice · ask your own clinician
Pregnancy. Contraindicated during pregnancy as aesthetic clinical trials exclude pregnant individuals, and elective biostimulatory procedures should be postponed.
Breastfeeding. Contraindicated during breastfeeding; elective biostimulatory procedures should be deferred until lactation is complete.

The evidence
One card per claim. Concentration, form, population and limitation sit with it, always visible.
Research in progress — check back soon. How we verify
The headline facial-volume-restoration claim's cited PMID resolves to an unrelated nasal-reconstruction surgical-flap paper, and the shared source for the neocollagenesis claim, while real, is misattributed: its own actual finding is a long-term retrospective volumetric-imaging study, not the gene-expression trial the packet describes.
The long-term tissue-remodeling claim's second cited source resolves to an unrelated foot-fracture CT-imaging paper.

What is still missing
The headline facial-volume-restoration claim's cited PMID resolves to an unrelated nasal-reconstruction surgical-flap paper, and the shared source for the neocollagenesis claim, while real, is misattributed: its own actual finding is a long-term retrospective volumetric-imaging study, not the gene-expression trial the packet describes.
Neither of the packet's two headline claims has an independently verifiable, correctly-attributed source. Both are withheld pending regeneration.
NeedsA corrected packet with citations that resolve to the papers whose actual findings match what is claimed.
The long-term tissue-remodeling claim's second cited source resolves to an unrelated foot-fracture CT-imaging paper.
