Mechanism of Action
This extract functions as an antioxidant, actively scavenging harmful hydroxyl radicals and superoxide anions. Its primary mechanism for skin brightening involves significantly inhibiting tyrosinase activity, thereby reducing melanin production. Furthermore, specific peptide fractions can modulate gene promoters, inhibiting VEGF and activating Hsp70.1, suggesting roles in angiogenesis regulation and stress response. Collagen hydrolysates within the extract enhance skin hydration by increasing levels of hydroxyproline and hyaluronic acid, contributing to anti-photoaging effects and improved moisture retention. It also exhibits film-forming properties.

Stability
The solubility of silver carp scale peptide (SCSP) is pH-dependent, with a notable decrease around pH 6, likely its isoelectric point. A significant reduction in biological activity was observed when extract was stored at 4°C for three months compared to fresh preparation, suggesting potential degradation and reduced efficacy over time.
Safety
Safety Profile
Comprehensive safety assessments by regulatory bodies such as CIR, SCCS, or FDA are currently unavailable for Silver Carp Extract in cosmetic applications. However, a specific peptide fraction derived from silver carp scales (SCSP-II) demonstrated safety in vitro at 0.01 mg/mL, showing no toxic or side effects in cell experiments.
