Lipopeptide (Biopeptide EL)

Overview

Lipopeptides represent a class of molecules in which a lipid moiety is covalently linked to a peptide chain. Biopeptide EL specifically uses a palmitoyl group to enhance skin penetration and bioavailability of the GQPR tetrapeptide sequence. Research has shown that lipopeptides stimulate new collagen production and hyaluronic acid synthesis within skin tissue. The palmitoyl modification makes Biopeptide EL highly compatible with the lipid-rich structure of cell membranes, facilitating cellular uptake and signaling that promotes extracellular matrix remodeling.

Mechanism of Action

Biopeptide EL interacts with cell membrane receptors, including Toll-like receptors, to stimulate intracellular signaling cascades that upregulate collagen and hyaluronic acid biosynthesis in dermal fibroblasts. The palmitoyl chain anchors the peptide in the lipid bilayer, prolonging receptor engagement and enhancing bioactivity compared to water-soluble peptides.

How to reconstitute

1/6Gather & prepare

Set up a clean workspace with all supplies ready.

1.Wash hands thoroughly, put on disposable gloves

2.Your 5mg peptide vial (lyophilized powder)

3.Bacteriostatic water (you'll need 2mL)

4.A 3–5mL syringe with 21–25 gauge needle for reconstitution

5.Alcohol swabs (70% isopropyl)

Use bacteriostatic water (0.9% benzyl alcohol) for multi-dose vials. Sterile water is only safe for single-use.
