i've been a fan of joan's for a while (she got me into skincare!!), so i knew i had to try this day and night cream when she introduced it. I actually don't really separate what i use for day or night. it depends how my skin is feeling. if i'm more dry, then i'll use the cream. if i need less moisture, i'll use the gel. sometimes i layer them also. i really like how it feels like i'm getting two products in one!
