You see the thing is this,  believe it or not your skin is designed to keep things out so it is actually quite difficult to get things under it. Yes if we rub garlic on our feet we can smell it on our breath within a few minutes and yes an aromatherapy massage can reach the parts that an ordinary rub down just can’t touch but it’s not like that for everything.  All that your average skin cream can hope to do is serve as a moisture trap or a barrier cream, working at or on the surface to prevent or modify moisture loss.
