I will use and buy this serum until the day I don’t care anymore. But right now I care a lot. I am loving the dewy glow it gives me. Right off the bat. Also—total plump of the cheeks and all the pretty parts of the face that could use a plump or boost. I mean this stuff is incredible. I have gotten so many compliments on my skin and I feel like it’s thanks to this miracle serum. Don’t get my wrong warmsunnyd · sephora.com
