Science
Mechanism of Action
This advanced polypeptide operates through several key pathways to enhance skin health. It significantly reduces inflammation by suppressing pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1β, and by modulating the NF-κB and MAPK signaling cascades. Concurrently, it exhibits strong antioxidant capabilities, effectively scavenging free radicals like DPPH and ABTS to mitigate oxidative stress. Furthermore, SR-(METHIONYL STURGEON POLYPEPTIDE-1) functions as a cell signaling protein, similar to Basic Fibroblast Growth Factor (sh-Polypeptide-1), actively stimulating fibroblast proliferation and the synthesis of collagen and other vital extracellular matrix components. This action leads to improved skin elasticity, reduced wrinkle depth, enhanced hydration by decreasing transepidermal water loss, and fortified protection against UVB-induced photodamage.

Key findings
- 01 In vitro studies utilizing concentrations from 0.05 mg/mL to 0.25 mg/mL have demonstrated significant reductions in inflammatory mediators (NO, IL-6, TNF-α, IL-1β) and enhanced antioxidant potential (DPPH, ABTS free radical inhibition) in LPS-induced inflammatory models.
- 02 At 0.125 mg/mL and 0.25 mg/mL, low-molecular-weight sturgeon skin collagen hydrolysate was shown to improve the repair of UVB-irradiated skin damage in a zebrafish model and reduce intracellular reactive oxygen species (ROS) and inflammatory cytokine expression in mouse fibroblast L929 cells.
- 03 A Siberian sturgeon cartilage hydrolysate at 5.0 mg/mL exhibited robust antioxidant activity, achieving DPPH· and HO· scavenging rates of 38.52% and 45.37%, respectively.
