Detailed answer

Arginine, an amino acid, plays a crucial role in moisturizers as it helps improve hydration and protect the skin. It acts as a humectant, drawing in moisture from the environment to keep the skin hydrated. Arginine also works as a skin-conditioning agent, helping to improve the texture and overall appearance of the skin. Additionally, it aids in strengthening the skin's natural barrier function, protecting it from environmental stressors and reducing moisture loss. Overall, arginine contributes to maintaining optimal hydration levels and supporting the overall health and wellbeing of the skin.
