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!

Hydrating serum
This product is not as hydrating as it claims for my 56 year old skin. I have to reapply several times a day. There's no irritation or stickiness which is great tho.
