After at least a month of using/testing the serum my face have become immune to this moisture. I could not go a day without applying this serum before my creams. Like I have said before this I have never used a serum & i tried days with & without the serum & you can definitely feel & see the difference. It holds the products longer in, Illuminates my face even more & it has helped my skin transform into baby soft skin, every time i apply a Clarins product I am bound to just run my fingers over my face..
I am continuing with this product!!
