PIPERIDINEPROPIONIC ACID.

Valuable CAS 26371-07-3 / SKIN CONDITIONING

Piperidinepropionic acid, also known as 1-PPA, is a potent anti-aging ingredient that significantly improves skin barrier function, enhances moisture retention, and refines skin texture. It actively works to mitigate signs of skin aging by addressing underlying cellular processes and rejuvenating damaged skin.

Science

Mechanism of Action

This ingredient primarily functions by inhibiting Serpin b3, a protein known to disrupt the skin's barrier integrity by impeding the proper digestion of corneocyte nuclei. This disruption can lead to abnormal stratum corneum formation and accelerated aging. By counteracting Serpin b3, Piperidinepropionic acid helps restore a healthy skin barrier, improving hydration and smoothness. Additionally, 1-PPA acts as an antagonist to Protease Activated Receptor-2 (PAR2) by binding to an allosteric pocket, suggesting a role in modulating inflammatory pathways and MAPK signaling.

Key findings

  1. 01 Clinical research from sources including MySkinRecipes and Shiseido indicates that continuous application of Piperidinepropionic acid at concentrations between 0.5% and 1% is highly effective. This utilization rate has been shown to significantly mitigate skin aging, inhibit Serpin b3 production, and rejuvenate damaged skin, leading to improved barrier function, moisture retention ability, skin texture, and overall smoothness on human skin.
