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.

This stuff is amazing! It has drastically helped repair my skin barrier. I had a flare up of dermatitis right before an important event and this helped clear it!
