Science
Mechanism of Action
This ingredient functions by enhancing the skin's natural ability to absorb and retain moisture, potentially by increasing hyaluronic acid content and forming a sphingomyelin shell. It contributes to improved skin elasticity and firmness by mitigating matrix degradation and supporting the synthesis of essential skin components, thereby imparting anti-aging effects. Furthermore, fish-derived proteins and peptides can inhibit tyrosinase activity and melanin production, leading to a brightening effect. Additional benefits include alleviating oxidative stress, reducing inflammation, protecting against DNA damage, and possessing antioxidant, antimicrobial, and photoprotective characteristics.

The Formula
Formulation
Stability
Small peptides and short polypeptides derived from collagen typically exhibit good water solubility. While collagen extraction often occurs in acidic conditions (pH 2.0-3.0), a specific optimal pH range for Fish Plasma Protein's stability in cosmetic formulations has not been directly reported. Proteins, in general, are sensitive to extreme pH values and high temperatures.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated 'FISH PLASMA PROTEIN'. However, 'Hydrolyzed Collagen', a related fish-derived ingredient, has been concluded by CIR to be safe for use in cosmetics. The FDA does not pre-approve cosmetic ingredients, and there are no specific federal regulations prohibiting fish proteins in cosmetics, with safety concerns addressed as they emerge.
