| Biological Activity | It is a synthetic peptide that mimics the action of snake venom component. It can bind to specific receptors on fibroblasts, stimulating the synthesis of extracellular matrix components such as collagen and hyaluronic acid. This helps in improving skin elasticity, reducing the appearance of fine lines and wrinkles, and enhancing overall skin texture. It also has potential anti – aging and skin – rejuvenating effects. |
| Storage Conditions | Store at – 20°C in a dry and dark place. Protect from light and moisture. Once opened, use appropriate aseptic techniques to prevent contamination. |
| Stock Location | Stock in USA |
| MOQ | 1g |
Palmitoyl Pentapeptide-3/4 functions by mimicking the activity of snake venom-derived peptides, specifically targeting fibroblast receptors. Upon binding, it activates intracellular signaling pathways that upregulate the synthesis of extracellular matrix (ECM) components, including collagen types I and III, hyaluronic acid, and fibronectin. This process strengthens the dermal structure, improves skin elasticity, and reduces the depth of fine lines and wrinkles. The palmitic acid moiety enhances its lipophilicity, optimizing penetration through the stratum corneum for efficient delivery to target tissues.
