Science
Mechanism of Action
Tuna extract and its collagen peptide derivatives exhibit antioxidant properties by neutralizing free radicals and inhibiting myeloperoxidase. They promote anti-aging and anti-wrinkle effects by downregulating matrix metalloproteinase (MMP) expression, upregulating tissue inhibitor of metalloproteinase-1 (TIMP-1), and reducing elastase activity, which collectively lead to increased collagen synthesis and fibroblast proliferation. Specific collagen peptides from bigeye tuna further decelerate skin aging by activating the TGF-β1 signaling pathway and inhibiting the MAPK pathway, while unsaturated fatty acids contribute to maintaining skin elasticity and moisture.

Stability
Pepsin-soluble and bromelain-soluble collagens from bigeye tuna skin exhibit stability within a narrow pH range of 4.30-4.70. While general skincare formulations often target a pH of 4.5-6.5 for product stability and skin barrier function, this ingredient requires careful pH consideration. High concentrations of tuna collagen peptides may lead to visible precipitation. The raw peptide powder can also possess a fishy odor, which may necessitate ozone oxidation for cosmetic suitability. The solubility and extractability of collagen are highly dependent on the pH of the extraction medium.
Conflicts
- High concentrations can lead to visible precipitation.
- Potential degradation or irritation if combined improperly with other strong active ingredients without careful formulation.
- High protein content might be a contributing factor for allergic reactions in some sensitive individuals.
Safety
Safety Profile
Tuna extract, as a specific cosmetic ingredient, has not been reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel. In the U.S., cosmetic products and ingredients do not require FDA approval prior to marketing, with manufacturers bearing responsibility for safety. Tuna extract is not listed on the FDA's list of prohibited or restricted cosmetic ingredients. However, a patent suggests that non-hydrolyzed nucleic acid material from tuna with low protein content is less prone to inducing allergic reactions, implying that high protein content in certain tuna extracts could be a consideration for allergenicity.
