The Ordinary Hyaluronic Acid 2% + B5 (Original Formulation) is the classic, fan-favorite hydration serum that The Ordinary officially re-released due to popular demand. It focuses purely on multi-depth surface hydration and gradual skin barrier strengthening.
Core Ingredients:
- 4 Forms of Hyaluronic Acid: Combines low-, medium-, and high-molecular-weight HA molecules alongside a next-generation HA crosspolymer. This allows the serum to penetrate and hydrate multiple layers of your skin's surface.
- Pro-Vitamin B5 (Panthenol): Works beneath the surface to encourage the skin to produce its own fatty acids and lipids, which naturally strengthens the skin barrier and improves moisture retention over time.
Texture & Sensory Experience:
- Rich and Viscous: This formula is noticeably thicker than the newer ceramide version.
- The "Sticky" Factor: Because it forms a plush, protective mesh on the skin's surface, it can feel slightly tacky or sticky immediately upon application. This texture is exactly what many longtime users love for creating a plump, dewy base.
