Having tried a few different serums from other brands recently, this is by for the best. I love the idea of using this before a moisturizer to really absorb the hyaluronic acid. Other serums I have tried feel sticky and made my skin feel almost like I had a mask on that needed to be peeled off. This is NOT sticky! Goes on like silk. Love it!
I've never been a big user of serums, but after I tried this in the Discovery Kit, I feel in love! It makes my skin feel so smooth and layers really well.
