Science
Mechanism of Action
This ingredient primarily functions as a humectant and skin conditioning agent, drawing moisture into the stratum corneum to improve hydration and maintain skin elasticity. Composed of small peptides and free amino acids, it is thought to penetrate the skin, providing essential building blocks for endogenous proteins like collagen and elastin. Additionally, its collagen oligopeptides may stimulate fibroblast activity, potentially increasing the production of new collagen, elastin, and hyaluronic acid, thereby strengthening the skin barrier and reducing the appearance of wrinkles.

Stability
Based on structurally similar hydrolyzed collagen derivatives, stable, clear solutions typically form at pH values above 6.5. It is important to consider that hydrolyzed collagen generally exhibits an isoelectric point (pI) between 3.68 and 5.7, a range where its stability and solubility may be reduced.
Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) Expert Panel has assessed and concluded that related ingredients such as 'Potassium Cocoyl Hydrolyzed Collagen' and 'TEA-Cocoyl Hydrolyzed Collagen' are safe for use, 'Potassium Stearoyl Hydrolyzed Collagen' itself has not undergone a specific safety review by the CIR Expert Panel.
