Evidence for skin

Each row is an outcome related to skin from a published study, strongest design first. Animal and cell results are labelled and are not human results. User reports are not counted as evidence here.

KPV for skin: outcomes in published studies
OutcomeResultStudy typeSource
Keratinocyte viability and IL-1betaKPV at 50 ug/mL restored cell viability and reduced IL-1beta secretion in PM10-exposed keratinocytes.In vitro (not a human result)Tissue & cell 2025, PMID 40073467
Skin permeationKPV did not permeate human skin by passive diffusion alone (below the detection limit of 0.01 ug/mL); microneedles and iontophoresis were needed.In vitro (not a human result)Journal of pharmaceutical sciences 2017, PMID 28343991
Cyclic AMP signallingKPV did not raise cyclic AMP in human keratinocytes (mechanism study; no clinical outcome).In vitro (not a human result)The Journal of investigative dermatology 2004, PMID 15102092

PubMed records for KPV and skin: 1 human, 1 animal (search counts, not studies we reviewed). Grades follow our evidence scale.

How strong is it?

Strongest evidence:In vitro evidence, 1 of 4Tissue & cell 2025, PMID 40073467

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.

Common questions

Does KPV help with skin?

The strongest study we summarise for skin is in vitro evidence, across 3 studies with an outcome for skin. That is not proof it works in people.

Is KPV approved for skin?

No. KPV is not FDA approved for any use, including skin.

What is the best peptide for skin?

There is no single answer. Our skin overview compares each candidate by evidence grade and legal status rather than by popularity.
