I am obsessed with this product! I originally bought it when I was in Paris and I loved it. It is the smoothest silkiest texture. A small amount goes along way. I put it on at night as part of my bedtime routine and the changes I have noticed my skin are amazing. I think the price point is good not too expensive and it lasts a long time it hydrates my face super well has a slight scent, but very pleasant. No greasiness.

Accutane holy grail!!

I’ve been on accutane for 2 months and have used this day and night. My skin has not flaked once and has appeared so hydrated despite taking a very drying medication! It’s very lightweight, non-stick, and quickly absorbs into my skin. I don’t usually write reviews but this is worth while for accutane users!
