Palmitoyl Hexapeptide-12

Also known as: Biopeptide EL, Pal-VGVAPG, Elastin-Stimulating Peptide, Lipopeptide EL

Palmitoyl Hexapeptide-12 (Biopeptide EL) is a lipopeptide composed of a hexapeptide sequence derived from the human elastin protein, conjugated to a palmitoyl fatty acid chain for enhanced skin penetration. It stimulates elastin production in dermal fibroblasts, helping restore the elastic resilience of aging skin. It is widely incorporated into anti-aging cosmeceutical formulations targeting skin firmness and elasticity loss.

Quick Answer

Palmitoyl Hexapeptide-12, marketed as Biopeptide EL, is a cosmetic peptide designed to stimulate elastin production in the skin. It consists of a six-amino acid sequence derived from human elastin conjugated to a palmitic acid chain for better skin absorption. In preclinical studies, it increases tropoelastin synthesis by dermal fibroblasts, helping restore skin elasticity and firmness that decline with age. It is used in professional anti-aging serums, typically combined with other signal peptides.

Key Facts

Mechanism
Palmitoyl Hexapeptide-12 contains the VGVAPG sequence, a bioactive fragment from the elastin protein that acts as a matrikine — a peptide signal derived from the extracellular matrix. When applied to skin, the palmitoyl chain facilitates penetration through the stratum corneum. The VGVAPG sequence binds to the elastin-binding protein (EBP) on fibroblast cell surfaces, triggering intracellular signaling cascades that upregulate tropoelastin gene expression. This stimulates de novo elastin fiber production and assembly, countering the age-related decline in elastic tissue that leads to skin sagging and loss of resilience.

Frequently Asked Questions

What does Palmitoyl Hexapeptide-12 do for the skin?
Palmitoyl Hexapeptide-12 specifically targets elastin production. Elastin is the protein responsible for skin's ability to "snap back" — its resilience and bounce. As we age, elastin production virtually stops (most elastin is made before puberty), and existing elastin fibers degrade. This peptide contains an elastin-derived sequence that signals fibroblasts to produce new tropoelastin, helping partially restore the elastic properties of aging skin.
How is Palmitoyl Hexapeptide-12 different from collagen-stimulating peptides?
Collagen-stimulating peptides like Matrixyl and palmitoyl tripeptide-1 primarily boost collagen production, which provides structural support and fullness to the skin. Palmitoyl Hexapeptide-12 specifically targets elastin, which provides flexibility and resilience. Both proteins are essential for youthful skin. Combining collagen- and elastin-stimulating peptides addresses the full spectrum of age-related dermal protein loss.
Can Palmitoyl Hexapeptide-12 be combined with retinol or vitamin C?
Yes, it is generally compatible with retinol and vitamin C. However, because retinol and high-concentration vitamin C serums can be irritating, it is best to introduce peptide products gradually when layering with actives. Apply water-based products first (vitamin C), then peptide serums, then retinol or oil-based products. Some formulators combine them in a single product for convenience.
