The Ordinary Hyaluronic Acid 2% + B5

The Ordinary Hyaluronic Acid 2% + B5 — multiple-molecular-weight hyaluronic acid serum with vitamin B5 (panthenol). Fragrance-free, water-based, lightweight. Available from major online retailers. in low-humidity environments, hyaluronic acid at the skin surface draws moisture from deeper layers if no occlusive or emollient is applied over it — skipping the moisturizer layer in dry conditions can worsen dehydration rather than improve it; the serum's tacky finish before it sets can feel sticky if over-applied; the high concentration of humectants means a little goes a long way, and applying too much delivers no extra benefit; the dropper format makes precise dosing slightly imprecise compared to a pump.

The Ordinary Hyaluronic Acid 2% + B5 is the hydrating serum that justifies including a dedicated moisture step at all. The formula layers multiple molecular weights of hyaluronic acid to bind water at different depths in the stratum corneum, with vitamin B5 (panthenol) adding a supporting humectant and soothing component. Fragrance-free, water-based, lightweight. It supports the routine specifically by adding a hydration buffer between cleanser and moisturizer that the niacinamide serum then absorbs into rather than sitting on top of. The honest trade-off: in low-humidity environments the surface HA can pull water from deeper layers if no occlusive moisturizer follows, so the CeraVe step after it is non-negotiable.
