Our reformulated The Ordinary Hyaluronic Acid 2% + B5 now includes 5 forms of Hyaluronic Acid and added Ceramides. This  formula provides instant plumping hydration, delivering softer, smoother and firmer skin. It effectively replumps dry, dehydrated skin, promoting suppleness and elasticity. With a combination of 5 forms of hyaluronic acid, including low-, medium- and high-molecular-weight molecules, a HA crosspolymer, and hydrolysed HA, this formulation hydrates multiple layers of the skin's surface. The addition of ceramides helps lock in moisture for long-lasting hydration. Pro-vitamin B5 contributes to reducing water loss, keeping the skin moisturised for an extended period. Testing has shown that this enhanced formula provides all-day plumping hydration, smoother-feeling skin, improved skin elasticity and reduced wrinkle and fine lines appearance.
