Science
Mechanism of Action
This ingredient's mechanism centers on its hydrolyzed collagen component, which is broken down into smaller peptides. These peptides serve as effective humectants, binding water within the skin to significantly increase hydration and diminish the appearance of dry or damaged skin by restoring suppleness. Furthermore, these peptides, along with their free amino acids, are believed to stimulate the dermal production of new collagen, elastin, and hyaluronic acid. The palmitoyl segment contributes emollient properties for skin softening and also acts as an antistatic agent and a mild cleansing surfactant.

Stability
For optimal stability, Palmitoyl Hydrolyzed Collagen performs best within a pH range of 5.0 to 6.5. This range is well-suited for skin applications, aligning with the physiological pH of the skin, which typically falls between 4.5 and 6.5. The isoelectric point (pI) of hydrolyzed collagen generally shifts to lower values, between 3.68 and 5.7, compared to native collagen.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated hydrolyzed collagen, concluding it is safe for use in cosmetic formulations. Clinical studies on hydrolyzed collagen have demonstrated no skin sensitivity, phototoxicity, or irritation. The FDA classifies gelatin, the source of collagen peptides, as safe. While some related derivatives, such as Cocoyl Hydrolyzed Collagen Ingredients, have been noted to potentially cause mild irritation at high or undiluted concentrations, no specific CIR assessment or restrictions have been identified for Palmitoyl Hydrolyzed Collagen itself.
