Argireline (Acetyl Hexapeptide-8) is a synthetic hexapeptide used topically to reduce the appearance of expression lines and wrinkles.

Matrixyl (Palmitoyl Pentapeptide-4) is a cosmetic signal peptide consisting of five amino acids (Lys-Thr-Thr-Lys-Ser) conjugated to a palmitoyl chain for enhanced skin penetration.

Collagen Type I is the most abundant protein in the human body and the predominant structural collagen in skin, bone, tendon, ligament, and cornea.

Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide consisting of the tripeptide sequence Gly-His-Lys conjugated to a palmitic acid chain.

Palmitoyl Tetrapeptide-7 (Pal-GQPR, also known as Rigin) is a lipopeptide derived from immunoglobulin G, consisting of the tetrapeptide sequence Gly-Gln-Pro-Arg conjugated to palmitic acid.

Collagen Type III is the second most abundant collagen in the body, found predominantly in skin, blood vessel walls, internal organs, and muscles.

Collagen peptides are short-chain amino acid sequences derived from enzymatic hydrolysis of native collagen (types I, II, and III).

Leuphasyl is a synthetic pentapeptide (Tyr-D-Ala-Gly-Phe-Leu) developed by Lipotec as a cosmeceutical anti-wrinkle active.
