Glycine is a naturally occurring amino acid that supports skin and hair health by boosting the effectiveness of cosmetic formulations. As a potent humectant, it attracts and retains moisture in the skin, promoting lasting hydration. In hair care, glycine conditions strands, enhancing softness and manageability without leaving buildup. Known for its anti-inflammatory properties, it also helps calm and soothe irritated skin. Glycine is commonly used in creams, lotions, shampoos, anti-aging products, and acne treatments.
