PACAP-38 (31-38), human, mouse, rat demonstrates potent, efficacious, and sustained stimulatory effects on sympathetic neuronal NPY and catecholamine production. PACAP is a potent activator of cAMP formation.

PACAP-Related Peptide (PRP), human is a 29 amino-acid region of the PACAP precursor protein.

Pactamycin is an antibiotic produced by Streptomyces pactum used as an antineoplastic agent. It is also used as a tool in biochemistry because it inhibits certain steps in protein synthesis.

Paired box protein Pax-5

Palmitoyl Tetrapeptide-7 decreases inflammation and improves skin firming and elasticity. Dipeptide-2 improves lymphatic circulation. Their anti-inflammatory properties help minimize eye puffiness and fluid retention under the eyes.

Palmitoyl Tripeptide-5 (PT-5) is a type of peptide molecule that is used in skincare products for its anti-aging and wrinkle-reducing properties. It is made up of three amino acids (glycine, histidine, and lysine) that are linked to a fatty acid called palmitic acid.

Palmitoyl Dipeptide-5 Diaminobutyloyl Hydroxythreonine Palmitoyl Dipeptide-6 Diaminohydroxybutyrate are two peptides that interact with the most relevant protein structures of the dermal-epidermal junction including laminin, integrin and various collagens.

Palmitoyl dipeptide-7 was found to enhance differentiation of the epidermis, basement membrane zone,and dermal fibroblasts.

Palmitoyl Hexapeptide-12 is a lipopeptide molecule consisting of a lipid connected to Hexapeptide-12. Unlike water-soluble peptides, Palmitoyl Hexapeptide-12 is highly biocompatible with skin’s natural structure.

Palmitoyl oligopeptide has the similar substructure of collagen type I and improves collagen synthesis based on a feedback regulation mechanism. Palmitoyl tetrapeptide-7 inhibits the expression of interleukine 6 (IL-6) being responsible for inflammatory processes in the skin.

Pentapeptide-4 activates certain genes involved in the process of extracellular matrix renewal and cell proliferation. Its 16-carbon aliphatic chain is for improving the penetration of the molecule through the lipid structures of the skin.Stimulates collagen I, III and VI fibronectin, elastin, glucosamnoglycans production.

Cosmetic ingredient for skin conditioning

Palmitoyl Tetrapeptide-20 is an ingredient to remedy white hair without making a hair coloration. This ingredient is capable of repigmenting hair from the roots: Palmitoyl Tetrapeptide-20 is an active ingredient that boosts Melanin production and helps stimulate the natural pigmentation of hair during regrowth.

Palmitoyl Tetrapeptide-3 (Rigin) is a synthetic peptide, corrspending to 341-344 amino acid sequenceof IgG human H-chain, with phagocytosis stimulating activity.

Pal-GHK consists of a short chain of three amino acids (GHK peptide) connected to palmitic acid. The palmitic acid is a fatty acid added to improve the peptide’s oil solubility and thus evaluate its skin penetration.

Palmitoyl Tripeptide-28 is the reaction product of palmitic acid and tripeptide-28. Palmitoyl Tripeptide-28 is the key in the regeneration of extracellular matrix as it stimulates the proteins synthesis in the extracellular matrix, inhibits the metalloproteinases that degrade the collagen, stimulates the production of proteases inhibitors and the synthesis of integrins.

Palmitoyl Tripeptide-38 is the reaction product of palmitic acid and Tripeptide-38. It penetrates deep into the dermis to boost the production of collagen and the synthesis of hyaluronic acid, particularly on the forehead.

Palmitoyl tripeptide-5 triflate is a component of cell transduction, and promotes the production of collagen. It is commonly used in anti-aging and anti-wrinkle cosmetic

The soothing peptide has highly specific anti-inflammatory activity, can effectively prevent and slow down the inflammation and symptoms caused by chemical stimulation, especially suitable for the care of sensitive and intolerant skin, and potentially reduce the production of melanin.
