Amino Acids + B5 Hydration Serum

The Ordinary Amino Acids + B5 Hydration Serum combines amino acids and vitamin B5 to hydrate the skin and support barrier function, addressing dryness, fine lines, and loss of firmness and elasticity. Amino acids (from the skin’s Natural Moisturizing Factors) provide enhanced barrier support, elasticity, and balance, while vitamin B5 offers surface and below-surface hydration and aids in skin repair and anti-irritant functions.
