Liquid silk
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!

Great product but pricy
I really like this product. It helps with “aged” skin- moisturizing but not oily or heavy feeling. It is pricy though.

Perfect for Glassy Skin
Love the feeling, ease of application, hydration, longevity/ duration, and all-day effect. Would be nice if they cost less, but here we are. Size is perfect for travel. Of course super hydrating products will be a bit sticky to touch, but I shouldn’t be touching my skin anyway. Only pops up when I need to put my face down for a massage or at the chiropractor. Love Avéne!
