I love this product. I received a sample in a previous order and tried it so ultimately ordered this regular size. It makes my make up/powder (I wear mac powder make up in compact) It helps the coverage and evens out the redness in my skin tone. It also seems to make it stay on longer. It just glides on and it very light.
In looking for a primer, I had no idea where to start so I googled 'best primers'.... this Mac prep& prime was the number one answer across the board and I totally agree with all of the positive reviews. This primer goes on smoothly so it doesn't feel heavy or gross - but you can still tell where you put it on your face! It has a shimmer to it, but it is unnoticeable once you put the rest of your makeup on. Stays on all day!! love it.
