I-Collagen tripeptide(CTP)iyunithi yesakhiwo encane kunazo zonke ye-collagen elungiswe ubuchwepheshe obuthuthukisiwe be-bioengineering, i-tripeptide iqukethe i-glycine, i-proline (noma i-hydroxyproline) nenye enye i-amino acid eyodwa.Ngamanye amazwi, i-collagen tripeptide empeleni iwukusetshenziswa kobuchwepheshe obuthuthukisiwe be-bioengineering ukuze ibambe izakhiwo ezincane zamangqamuzana kuma-molecule amakhulu e-collagen awusizo esikhumbeni.Isakhiwo sawo singaboniswa kalula kuGly-xy, futhi isilinganiso sesisindo sawo samangqamuzana angama-280 dalton.Ingakwazi ukumuncwa ngokuphelele umzimba womuntu ngenxa yesisindo sayo esincane samangqamuzana.Ini'Ngaphezu kwalokho, ingangena futhi ngempumelelo ku-stratum corneum, i-dermis namaseli ezimpande zezinwele.

I-Collagen tripeptideinesisindo esincane samangqamuzana, uma iqhathaniswa nesakhiwo esiyisisekelo se-collagen yesikhumba, ingamuncwa ngokuqondile umzimba womuntu ngaphandle kokubola, izinga lokumunca lingaphezu kuka-99%, kanye nezikhathi ezingama-36 ze-collagen evamile.
