Science
Mechanism of Action
As a skin conditioning agent, serum proteins, particularly in their hydrolyzed form, are instrumental in maintaining optimal skin health. These proteins, along with their smaller peptide derivatives, act as crucial signaling molecules that initiate the skin's self-repair mechanisms. This signaling stimulates the replenishment of essential structural proteins such as collagen and elastin, which in turn contributes to enhanced skin firmness, improved elasticity, and a visible reduction in the appearance of wrinkles.

Stability
The stability of serum proteins in cosmetic formulations is critically dependent on precise pH control, ideally within a narrow range of 4.0 to 6.5. Native serum proteins generally exhibit limited water solubility; therefore, they are often hydrolyzed into smaller fragments to improve their suitability for water-based products. High concentrations can introduce physical instabilities, manifesting as increased viscosity, aggregation, precipitation, and particle formation, necessitating careful formulation optimization and the strategic use of excipients to mitigate these challenges.
Safety
Safety Profile
While serum protein itself has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel, other broad categories of proteins and peptides, including those derived from plants, tissues, and silk, have generally been deemed safe for use in cosmetic products. It is important to note that the FDA does not require pre-market approval for cosmetic ingredients, with the exception of color additives.
