Alpha-lipoic acid (ALA) serves as a potent scavenger with anti-inflammatory properties, enhancing the clinical characteristics of the skin, particularly addressing roughness caused by photoaging. Simultaneously, its powerful antioxidant nature directly scavenges a wide range of reactive oxygen species (ROS), offering protection to human keratinocytes against oxidative damage induced by UV exposure. This versatile compound interacts effectively with both water and lipid-soluble antioxidants, thereby reinforcing the antioxidant defense network. Furthermore, when combined with liposomes, alpha-lipoic acid contributes valuable raw materials for skin regeneration by replenishing lipid molecules and maintaining optimal moisture levels.
