Daily Hydration

Hydration is about water in the skin rather than oil, which is why oily skin can be dehydrated and very often is. The ingredients that do this work are humectants: glycerin, hyaluronic acid, panthenol and urea at lower concentrations. They draw water into the upper layers, and they hold it best when something sits over the top to slow evaporation. Skin that feels tight after cleansing usually needs this rather than a richer cream.
