I use this as a base for foundation and it really does make a huge difference. I find that my foundation goes on smoother and looks more flawless versus when I only apply moisturizer. I also find that my face is a bit illuminated after I apply this due to the pearlescent nature of the cream. I love it and it stays on longer and seems to be more waterproof than the Lander Vanishing Cream so it doesn't melt off the skin when you go out in the sun. You can apply it with a damp cosmetic sponge to build up the staying power as well then use the same damp cosmetic sponge to apply your foundation and your makeup will stay on like nobody's business.
What is your tried and true base?
