What is the difference between hydration and moisturization?

    I can see a slight change in the appearance of my skin. I do like this product, especially that it’s unscented. I like the light texture and how it makes my skin feel less dry.

    This is such a lovely body cream. It helps with crepeyness, and my skin is so soft! I use it every other day and it really is special. Worth the price!

    Silly, luxury cream that covers a lot of ground and spreads out thoroughly. Doesn’t moisturize, exactly, but definitely smooths the skin texture and probably makes moisturizers more effective.
