Wow this is great. It absorbed well in my skin. No oily feeling. My skin is very dry and it did a great job. We will see how well it works on my wrinkles.

I felt like my skin dealt smoother and actually felt firmer. I shared done with my girlfriend and she loved it to. She ended up buying it but not from Birchbox, so I pushed her to sign up.
