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.
