Octyldodecyl PCA is a compound based on L-PCA (pyrrolidone carboxylic acid), a natural component of the skin's Natural Moisturizing Factor. The molecule combines a skin-related lipid component with the moisture-binding PCA part, creating a good match with the natural balance of moisture and skin lipids (the hydrolipidic balance, mention in training purpose). Thanks to this structure, Octyldodecyl PCA spreads evenly over the skin surface. Octyldodecyl PCA supports the skin barrier and helps maintain the natural moisture level. As a result, the skin feels comfortable, supple, and cared for.
