If pictures of Jan Crouch without makeup exist, they are extremely well-hidden as of 2015. There is a humor website called Jan Crouch Without Makeup, but the spoof site shows no pictures of the televangelist without at least some makeup.
Jan Crouch is known for wearing perhaps excessive amounts of eye makeup and pink lipstick when she appears in public. There are a few pictures on the Jan Crouch Without Makeup site that appear she is using less blush and less lip color than usual for her. In every picture, even those with a bit less makeup, her eye makeup is done to the point of extravagance.
