I love Pinterest dearly. Without it, my life would be less colorful, less creative, and—more importantly—I may have never discovered that the cure for deodorant stains lay in my jean drawer. Genius. But sometimes Pinterest leads me astray with false promises—particularly when it comes to beauty tutorials—and I’m left with sad, confused feelings and (in one unfortunate instance) bleeding gums. The thing about these beauty tutorials is that they’re not always the most reliable.
