Science
Mechanism of Action
This polypeptide operates through a sophisticated mechanism driven by functional groups such as lysine and 3,4-dihydroxyphenylalanine (DOPA). Lysine, possessing a high isoelectric point, carries a positive charge at physiological pH, which attracts negatively charged skin cells like epidermal cells and fibroblasts, thereby stimulating wound healing. The DOPA group facilitates strong adhesion by readily combining with atmospheric oxygen to form a high molecular weight network polymer via oxidative cross-linking. Together, these components form a protective barrier on the skin, enhancing cell adherence, migration, and growth to accelerate tissue repair. Furthermore, S-Mussel Polypeptide-1 exhibits antioxidant, anti-inflammatory, antibacterial, and cell-protective effects, and can alleviate inflammation, inhibit angiogenesis, and increase the expression of crucial skin barrier and tight junction-related proteins.

Key findings
- 01 Mefp-1 (a mussel adhesive protein) demonstrated tissue adhesion, such as skin-to-skin, with a tensional strength of approximately 1.5 N/cm² at 40 mg/mL, with strength increasing after 15 minutes of tissue pressing.
- 02 AdhPep3, an adhesive peptide from mussel protein, effectively mitigated angiogenesis-related cytokines (VEGF, IL-8, IL-6) in HaCaT cells stimulated with LL-37, a model for rosacea, suggesting anti-inflammatory and anti-angiogenic properties.
- 03 A recombined mussel adhesive protein significantly promoted HaCaT cell growth at 30 µg/mL and facilitated effective repair of damaged skin in mice within 14-21 days, showing no significant toxicity up to 90 µg/mL.
- 04 Recombinant mussel adhesive proteins (rMAPs) in clinical trials provided significant relief from erythema, flushing, and capillary dilation post-microneedle treatment, and improved symptoms of dryness, tightness, and flaking in sensitive skin, with no noticeable adverse reactions.

The Formula
Formulation
Stability
While mussel proteins exhibit high solubility across a broad pH range (2.0 to 13.0) during extraction processes, the optimal pH for the stability of S-Mussel Polypeptide-1 specifically within cosmetic formulations has not been defined. General protein stability is inherently pH-dependent.
Safety
Safety Profile
Formal regulatory assessments by CIR, SCCS, or FDA for 'S-MUSSEL POLYPEPTIDE-1' are currently insufficient. However, mussel-derived peptides generally demonstrate good biocompatibility and low immunogenicity. Clinical trials with recombinant mussel adhesive proteins (rMAPs) have shown a favorable safety profile, reporting no noticeable adverse reactions or significant side effects.
