palmitoyl tetrapeptide

Palmitoyl tetrapeptide is an analog of the N-terminal part of lipoprotein from the outer membrane of E. coli.

Palmitoyl tetrapeptide-7 is a cosmeceutical peptide that stimulates type I collagen, fibronectin, and hyaluronic acid production in skin.1Formulations containing palmitoyl tetrapeptide-7 have been used in the treatment of photoaging, dark circles, and undereye puffiness. 1.Bucay, V.W., and Day, D.Adjunctive skin care of the brow and periorbital regionClin.

Palmitoyl Tetrapeptide-20 (PTP20) is a bioactive peptide known to preserve the function of follicular melanocytes and is reported to be used as an ingredient in cosmetics [1].

Palmitoyl tetrapeptide-20 (PTP20) TFA is a biomimetic peptide and acts as an agonist of α-MSH. It protects follicular melanocytes by boosting catalase expression and activating melanogenesis.

Palmitoyl tetrapeptide-10 is a bioactive peptide that works synergistically with other active ingredients to increase the expression of corneodesmosin (a marker of keratinocyte adhesion) and filaggrin (a marker of keratinocyte terminal differentiation), thereby reducing skin permeability and improving skin barrier function. Palmitoyl tetrapeptide-10 can be used in research on sensitive skin syndrome and skin pigmentation.

Palmitoyl Tetrapeptide-3 (Rigin) (Rigin) is a synthetic peptide, corrspending to 341-344 amino acid sequence of IgG human H-chain, with phagocytosis stimulating activity.Palmitoyl Tetrapeptide-3 stimulates expression of GCP-2 (Granulocyte Chemotactic Protein), which is a chemotactic protein that can recruit cells involved in the preparation and cleansing of the site, to damaged areas.
