Let me tell you, I am recently starting to take care of my skin and it shows. I did a research on this and found a few reviews from make up artists that made decide to give it a try, and is Korean and we all know they have THE BEST SKIN EVER! I put it on I wasnt totally sure it was working... and then Im like... is my skin smoother... wait, that sagging around my mouth! What! Cool!I took a picture and see the difference on each side and even the height of my eyes! My recommendation is put it on way before make up and apply your foundation with a wet sponge.
