Great lotion for very dry skin
Style: Updated Formula
I had a laser done on my face and the products they gave me weren't working. This came highly recommended so I gave it a try. I'm very glad I did! It moisturized my face really well without appearing greasy. I used the rest when my face got dry from winter (in th midwest). Felt very rich and smooth. Medium thickness.
