L-Arginine Powder

L-Arginine Powder is a high-purity, water-soluble amino acid widely used in cosmetic and personal care formulations. It acts as a skin-conditioning and pH-adjusting agent, helping to neutralise acids and stabilise formulations, especially those containing AHAs like glycolic or lactic acid. L-Arginine also supports skin hydration and barrier function, leaving the skin feeling smoother and more comfortable. Commonly used in serums, creams, lotions, hair care products, and professional treatments, it is suitable for sensitive-skin formulations and is valued for its gentle, skin-friendly profile.
