This make-up base is amazing! I used it under my foundation and I experienced no signs of diamond face! It also seems to help make the make-up stay put. Awesome thing is how it doesn't feel like you've applied anything at all to your face. Super light on the face and makes it feel all nice and soft. :3
Other make-up bases tend to be too oily for my skin, and cause it to breakout. No such thing this make-up base. I really hope they don't discontinue it!!!
