I love Skinfix barrier and all its range. But had one small pot and Vichy serum (from one of my SephoraUK beauty bag). I love playing with makeup and skincare, besides not having enough time to do any routines. So spray drops of the Vichy serum on the Skinfix moisture was a saver in this weather, and I wash my face with hot water. It left skin so soft, so smooth. If you use it at night, you will wake up with so fresh, no bags under the eyes, as if you have a new skin layer. I use whats left in my hand for my neck and can see quick tighten results. I highly recommended it and did not need that much serum, just two sprays. As you can see, I use it all and will take from the full-size one to make a new mixture when the pot is empty.
