Science
Mechanism of Action
While the precise mechanism of this specific complex is not fully elucidated, its components suggest multi-faceted activity. The sh-polypeptide aspect is likely an EGF-mimetic, akin to sh-Oligopeptide-1 (Epidermal Growth Factor), which functions by engaging epidermal growth factor receptors (EGFR) on keratinocytes. This activation accelerates new skin cell production and enhances the synthesis of vital structural proteins like collagen and elastin, thereby promoting skin repair, self-regeneration, and improved barrier function. Additionally, the rainbow trout protein hydrolysate component generally contributes antioxidant and enzymatic inhibitory activities (ACE and DPP-IV), offering broader protective benefits.

Stability
Specific stability data for this exact ingredient is limited. However, related rainbow trout protein hydrolysates have demonstrated stable or increased antioxidant activity across a broad pH range (1-9) and under heat exposure (100°C for up to 240 minutes). As a peptide, general stability considerations apply, including potential sensitivity to extreme pH values, protease activity, and strong oxidizing agents.
Safety
Safety Profile
The FDA has not found products containing similar variants (e.g., sr-Rainbow Trout Oligopeptide-1 sh-Polypeptide-13) to be safe and effective for drug product approval, which differs from cosmetic ingredient safety assessment. General concerns exist regarding EGF-mimetic ingredients due to their growth factor properties and the theoretical potential for tumorigenesis if overexpressed, as EGF signaling is implicated in numerous tumor cells. While sh-oligopeptide-1 itself may not directly cause cancer, caution is advised for individuals with a history of skin cancer. 'sh-EGF' (sh-oligopeptide-1) is authorized as a cosmetic ingredient in various concentrations for general use, but its long-term risks remain undefined.

Verdict
Despite promising theoretical mechanisms related to skin regeneration and protection, the lack of specific clinical data for this exact ingredient and the undefined long-term safety profile for its EGF-mimetic components necessitates further rigorous research before a definitive recommendation can be made.
