How to spot a FAKE MAC studio fix foundation

How to spot a FAKE MAC studio fix foundation:

1. check whether the lettering of the shade and the bar code is the same. if they are the SAME -> it's FAKE!

2.the bar code contains 1 letter & 2 numbers with different lettering (or print) with that of the shade.

usually the lettering (or print) of the bar code is more dominant than the lettering of the shade

3. the bar code printed on the foundation itself should be the same number printed in the box. and located at the bottom part of the box.

4. the lettering of the shade is relatively thin or slender in form.

see the attached picture to determine the difference between the bar code and the shade
