Great product! I'm still learning about skin care and wasn't sure what a canvas base was, but the directions were clear. Even without foundation, applying the product gives a smoother, more polished look. As the directions say, you just need a tiny amount ("the size of a pearl") so one tube will go a long way. It's not greasy or oily. I plan to buy one when this review sample runs out, which probably won't happen for a long time.
