Original Formula Hydrating Water Serum — Hyaluronic Acid 2% and B5

The version many people started with, still made the same way. Four molecular sizes of hyaluronic acid sit at 2% here alongside panthenol, giving a slightly viscous, glossy fluid that grips water at the surface and cushions the look of dry patches. Apply to skin that is still slightly damp from cleansing, then seal with a cream or oil so the moisture has somewhere to stay. Morning and evening both work. Lines that come from dehydration tend to look softer with steady use.
