Performance & Formulation Insights for AccessPEP MPcell

A Multi-Pathway Approach to Skin Rejuvenation

AccessPEP MPcell operates across multiple anti-aging pathways for comprehensive, visible results. This synergistic blend combines advanced lipopeptides with a brightening lipoamino acid to simultaneously firm, lift, smooth wrinkles, and even skin tone.

Collagen & Extracellular Matrix Synthesis: Palmitoyl Pentapeptide-4 (a fragment of pro-collagen I) acts as a potent signaling molecule, stimulating fibroblasts to increase collagen I, III, IV, fibronectin, and hyaluronic acid. This helps rebuild the dermal matrix, reducing wrinkle depth and improving firmness.
Enhanced Firmness & Lifting: Myristoyl-conjugated tripeptide and tetrapeptides are optimized for superior skin affinity and penetration. They support cellular communication and reinforce the dermal–epidermal junction, improving skin cohesion, elasticity, and delivering a tangible “lifting” sensation.
Melanin Control & Brightening: Methyl Undecenoyl Leucinate acts as an antagonist to the α‑MSH receptor on melanocytes. By inhibiting this pathway, it helps control melanin production, visibly reducing the appearance of age spots and promoting a more even, radiant skin tone.

Formulation Guidelines & Technical Advantages

AccessPEP MPcell is an oil-soluble liquid ideal for the oil phase of creams and lotions, or for anhydrous serums. In emulsions, add to the oil phase before emulsification or during the cool-down phase below 40 °C to protect peptide integrity. The complex is stable within a typical cosmetic pH range of 4.5–6.5. Its multi-active design streamlines development, enabling lifting, firming, anti-wrinkle, and brightening benefits from a single ingredient.

Yes. It pairs well with antioxidant Vitamin C derivatives and can complement retinol regimens by supporting the skin barrier. Always conduct stability testing on the final formula.

It is oil-soluble due to the fatty acid chains on the peptides, and should be added to the oil phase or during cool-down.

It contains Methyl Undecenoyl Leucinate, which helps inhibit melanin production by antagonizing the α‑MSH pathway, reducing the visibility of age spots and helping prevent new ones.

The complex performs well in formulas with a pH between 4.5 and 6.5.
