Palmitoyl Pentapeptide-4

Palmitoyl Pentapeptide-4 คำอธิบาย

Palmitoyl pentapeptide-4 is a synthetic peptide comprised of five amino acids and palmitic acid, a fatty acid found naturally in skin. The fatty acid addition is important since it aids penetration and helps stabilize the peptide as it journeys through skin’s uppermost layers.

Originally launched in 2000 by cosmetics ingredient lab Sederma under the trade name Matrixyl®, it is now produced by other manufacturers under different names and different amino acid sequences, including BB-Biont™. Palmitoyl peptapeptide-4 is currently the most commonly used peptide in skin care products.

Thanks to its length of time on the market, there is a breadth of research regarding the efficacy of palmitoyl pentapeptide-4 in improving the look of fine lines and wrinkles. It is a signal peptide, a class of peptides that can kickstart certain cellular processes. In this instance, palmitoyl pentapeptide-4 sends signals to skin to boost collagen, elastin, and glycosaminoglycans – all key substances in maintaining skin’s youthful bounce and firmness.

In addition to its ability to improve skin’s elasticity, this peptide also improves skin hydration through regulating levels of hyaluronic acid. The result is skin that looks plumped and healthier.

The independent Cosmetic Ingredient Review panel has ruled palmitoyl pentapetide-4 safe in its current use in cosmetics. As a testament to its potency, its current maximum usage rate in leave-on products is 0.0012%.
