Peptides: Signaling Molecules for Anti-Aging

Peptides are short amino acid chains (2-50 residues) that communicate with skin cells to trigger specific biological responses — among the most targeted evidence-based anti-aging ingredients.

Signal Peptides (Collagen Stimulation)

• Matrixyl (Palmitoyl Pentapeptide-4): Mimics broken collagen; 31% wrinkle reduction at 3-5%
• Matrixyl 3000: Palmitoyl Oligopeptide + Palmitoyl Tetrapeptide-7

Neurotransmitter-Inhibiting Peptides (Expression Lines)

• Argireline (Acetyl Hexapeptide-3): Inhibits SNARE complex; effective at 5-10%
• Snap-8 (Acetyl Octapeptide-3): Extended Argireline version

Carrier Peptides

• GHK-Cu (Copper Peptides): Wound healing, collagen synthesis, antioxidant; 0.5-2 mg/ml

OEM Formulation Strategy

Most effective: combine 2-3 peptides from different categories. Differentiated combination: Matrixyl + Argireline + GHK-Cu = complete anti-aging coverage.

Formulation Challenges

Peptides degrade in aqueous systems, sensitive to pH/temperature, limited penetration. Solutions: encapsulation, lyophilization, liposomal delivery, iontophoresis-compatible serums.
