Sorbitol is a safe, non-irritating, multifunctional plant sugar derived from blackberries, apples, cherries, and plums. In skincare, it primarily functions as a humectant and texture enhancer. It is a natural prebiotic that helps protect the skin from harmful bacteria and infections. Additionally, sorbitol has anti-aging properties, conditions the skin, and improves its barrier function. It acts as a slip agent, making products easy to apply and spread, while also imparting a pleasant feel to the skin. Sorbitol is commonly used as a mild surfactant, especially in hair formulations, as it effectively cleanses the hair and scalp by trapping dirt and making it more water-soluble.
