PCA is widely used in the cosmetic and skincare industry due to its excellent moisturizing properties. It acts as a humectant, helping to retain moisture in the skin, making it a key ingredient in hydrating creams, lotions, and serums. Its ability to improve skin elasticity and reduce dryness makes it suitable for products targeting aging or dehydrated skin. Additionally, PCA is incorporated into hair care formulations to enhance hair hydration and manageability. Its gentle nature also makes it suitable for sensitive skin types, often found in products designed to soothe and repair the skin barrier.
