Science
Mechanism of Action
The precise mechanism of action for PENTAPEPTIDE-71 is not explicitly detailed in available research. However, other pentapeptides exhibit diverse bioactivity. Some, such as Palmitoyl Pentapeptide-4, are known to stimulate the production of extracellular matrix proteins like collagen (Type I, III, IV), elastin, fibronectin, and hyaluronic acid, which contributes to improved skin elasticity and a reduction in wrinkle depth. Other pentapeptides, including Pentapeptide-18 and Pentapeptide-3V, are posited to modulate neuromuscular communication, influencing neurotransmitter release or receptor binding to diminish the intensity of muscle contractions responsible for expression lines. Additionally, certain pentapeptides have been identified as selective MC1R agonists, enhancing melanin synthesis and activating oxidative stress responses, suggesting roles in pigmentation and anti-photoaging.

Stability
Specific stability data for PENTAPEPTIDE-71 is not readily available. However, peptides generally achieve optimal stability in aqueous solutions within a pH range of 3 to 5 to minimize deamidation and oxidation. Degradation pathways include hydrolysis (particularly at Asp-Pro motifs), deamidation (especially of Asparagine and Glutamine residues at alkaline pH), and oxidation (electron-rich residues like Methionine, Cysteine, Tryptophan, Tyrosine, which accelerates at pH above 7). Lyophilization (freeze-drying) can significantly enhance peptide stability.

Safety
Safety Profile
Specific safety assessments for PENTAPEPTIDE-71 by regulatory bodies such as CIR, SCCS, or FDA are not publicly available. However, related pentapeptides like Myristoyl Pentapeptide-4, Palmitoyl Pentapeptide-4, and Pentapeptide-4 have been concluded as safe for use in cosmetics by the CIR Expert Panel. Pentapeptide-18 is also regarded as safe with an excellent tolerance profile, showing no skin irritation, allergic reactions, or serious adverse effects in studies.
