Note that NO moisturizer will actually 'get moisture [back] into your skin'. A moisturizer is basically a vapour block. What it does is create a barrier (with oil or other non-water soluble component) that prevents moisture in your skin from evaporating. Any other claims made by cosmetics manufacturers/peddlers are just marketing hype.
There are some cream/moisturizer ingredients that would, in principle, be able to attract some water from the surrounding air and into your skin, but their concentration and limited ability to penetrate into deeper skin layers (i.e. beyond the stratum corneum) makes it questionable whether they have any real effect. Plus, higher concentrations will actually have the opposite effect. Since they are mostly limited to penetrating the SC, rather than attracting moisture from the air, they will actually start attracting moisture from the deeper skin layers and thereby increase dehydration.
Thanks for that. You learn something new every day
