Palmitoyl Tripeptide-1
ChemicalSubstanceA signal peptide that delivers the GHK matrikine sequence to dermal fibroblasts via a palmitoyl tail, stimulating collagen I, III, and IV synthesis and fibronectin production.
-
Pantothenic acid
ChemicalSubstanceWater-soluble B vitamin and the intracellular metabolite of dexpanthenol in skin tissue. Supports energy metabolism, fatty acid synthesis. Drives keratinocyte proliferation and fibroblast function.
-
Peptides
ChemicalSubstancePeptides are short amino‑acid chains that act as targeted signalling molecules in skincare, directing fibroblasts, melanocytes, immune cells, and neuromuscular junctions.
-
Phytoceramides
ChemicalSubstancePlant-derived ceramides taken orally, with research showing improved skin hydration after 12 weeks of consistent supplementation.
-
Polyunsaturated fatty acids
ChemicalSubstanceA class of dietary fats defined by multiple double bonds in their carbon chain. Includes the omega-3 and omega-6 families.
-
Proline
ChemicalSubstanceAn amino acid that forms the structural backbone of the collagen triple helix, where it provides rigidity and resistance to mechanical stress.
-
Pyrrolidone carboxylic acid
ChemicalSubstanceA naturally occurring humectant produced in the stratum corneum from filaggrin-derived glutamine. One of the largest single components of natural moisturising factor (NMF) by volume.
