I use this as the last step in my routine to seal in the moisture before applying sunscreen or a sleeping pack. At first I didn't really see a difference, but one day my skin was red and irritated in a certain area and I was sure I was going to need concealer to cover it up. I put on my snail gel cream, left the bathroom to get dressed, and when I came back 5 minutes later the redness was gone! I cannot live without this!!
