I never heard that one. I'll stay away from Mary Kay. Foundation evens out skin tone, nothing more.
Sounds like someone didn't know how to pick the right shade.
I'm no fan of foundation make-up. God made the human face with skin that varies in shade, color, and even in transparency. Foundation makeup creates an opaque, monotone "mask" that gives the human face the appearance of being plastic or clay, which I personally find unattractive, unnerving and unappealing. If someone is appearing under harsh lighting conditions (i.e. on stage or in a studio), foundation makeup is essential to overcome the skin's natural transparency, as overly-bright studio lighting makes a person's natural skin appear pale and bloodless.
A skilled make-up artist strives to re-create the appearance of natural skin tones, even though the materials are opaque. When done well (and IMO sparingly) the results are uncanny. But under natural lighting conditions, I see no reason to do so, and from this man's POV, the average woman must be using a paint roller to apply their make-up.
