A lightweight, water-based serum that supports skin hydration, elasticity, and smoothness. With concentrated amino acids and pro-vitamin B5, it nourishes and protects the skin barrier for a healthy, dewy glow.
Give your skin a daily dose of hydration, strength, and resilience with The Ordinary Amino Acids + B5 30ml — a minimalist yet powerful water-based serum that mimics your skin’s Natural Moisturizing Factors (NMF). This ultra-lightweight formula features a concentrated blend of essential amino acids and pro-vitamin B5 (panthenol), working together to deeply hydrate, nourish, and support the skin barrier. With consistent use, it helps restore moisture balance, replenish lost nutrients, and maintain smooth, healthy, and radiant skin for all skin types — even sensitive or stressed skin.
Amino acids are the essential building blocks of proteins in the skin, such as collagen and elastin, playing a vital role in maintaining hydration, elasticity, and repair. This formula delivers a potent 17% concentration of naturally occurring amino acids, including arginine, lysine, histidine, and proline. Complementing this is 5% pro-vitamin B5 (panthenol), a humectant that locks in moisture and soothes irritation. Together, they strengthen the skin barrier, boost suppleness, and protect against environmental stressors.
