mac face and body coverage

Today I used Mac face and body as a foundation for the first time. I have used studio fix but not this one because I didn't think it would be good enough coverage when I had acne. Now my acne is gone I only need the foundation to even out skin tone and cover freckles of different pigments. I decided to buff in the foundation and then build up the foundation to get the extra coverage. Sadly this did not work for me. My skin had pigments that are so uneven that they could not be covered and I just looked like I was wearing no make up at all but in a bad way. I have used this on a client today who insisted that I bring this product for her. It worked very well on her skin as she has perfect skin to begin with. It gave her a beautiful sheen that looked so glowy and healthy. Anyone with any skin problems or imperfections should avoid this as it really is just a sheer foundation that in my opinion can not be built up in coverage.
