More is more? The latest viral beauty challenge [1] taking YouTube by storm is in pursuit of the ever-elusive perfect shade [2] of foundation [3]. Beauty vloggers like Nyma Tang [4] and Laura Lee [5] have taken up the "Mix My Foundation" challenge with highly entertaining (and often successful) results. The challenge? To mix every single foundation in your makeup kit and blend the different shades together on your face.

While mixing two or three shades of foundation [6] may be easy enough, what about 27? That's the number of foundations Manny Mua [7] applied in his tutorial. The vlogger deemed the final product "the foundation to end all foundations" — high praise from a beauty expert. Watch these videos to see each artist's take on this hilarious challenge and get inspired to recreate this experiment at home.
