Valuable / HUMECTANT, SKIN CONDITIONING

Hydrolyzed Sturgeon Extract is a multi-functional ingredient derived from sturgeon protein, recognized for its comprehensive skin benefits. It acts as a potent antioxidant and anti-inflammatory agent, while actively supporting skin structure by enhancing collagen production and inhibiting its degradation. Furthermore, it functions as an effective humectant, promoting optimal skin hydration and overall conditioning.

Science

Mechanism of Action

This extract operates through several key mechanisms to improve skin health. It exhibits strong antioxidant activity by directly scavenging free radicals, such as DPPH, and reducing intracellular reactive oxygen species (ROS), thereby mitigating oxidative stress. Its anti-inflammatory properties stem from inhibiting the expression of pro-inflammatory cytokines like IL-1β, IL-6, TNF-α, and Cox-2. Structurally, it boosts collagen Iα1 content and significantly suppresses matrix metalloproteinase (MMP) activity, enzymes responsible for collagen breakdown. Additionally, as a humectant, it draws and retains moisture, enhancing skin hydration and maintaining a healthy stratum corneum.

Stability

Protein hydrolysates generally exhibit reduced solubility near their isoelectric points, typically in the pH 4.5-5.5 range. For optimal stability and functional properties, Hydrolyzed Sturgeon Extract is best formulated outside this range, with optimal hydrolysis conditions often reported between pH 6 and 8.5.
