Science

Mechanism of Action

This extract operates as a sophisticated skin conditioning agent, actively promoting skin health and hydration. Its unique hydrolyzed salmon roe proteins are theorized to enzymatically disrupt cellular adhesions, facilitating a gentle exfoliating action. Furthermore, it acts as an antioxidant, effectively neutralizing oxidative damage induced by UVB radiation.

Key findings

  1. 01 A hydrolyzed roe cream demonstrated a significant reduction in skin redness and irritation within 24 hours post-chemical peel. It also enhanced skin hydration and moisturization within 8 to 24 hours.
  2. 02 Clinical application of a hydrolyzed roe cream resulted in statistically significant decreases in brown spot counts (mean change, -46 at week 8, -35 at week 12), red spot counts (mean change, -12 at week 8), and general dyschromia (mean change, -18 at week 8). Furthermore, it improved wrinkle appearance, elevating it from the 45th to the 70th percentile by week 12.
  3. 03 Topical application of hydrolyzed salmon roe protein, twice daily, improved overall skin clarity and was well-tolerated, with fewer reported instances of stinging and burning compared to glycolic acid formulations.

Stability

Proteins and peptides resulting from hydrolysis are inherently susceptible to chemical degradation influenced by factors such as pH fluctuations, ionic strength, temperature, light, oxygen, and various reactive compounds. The presence of metal ions, including calcium, copper, and iron, may induce protein precipitation. Stability can be notably enhanced through advanced micro-coating techniques.
