It's no secret that one of our favorite areas of exploration here at Who What Wear is the magic that is Jennifer Lopez. From her impossibly cool style to her mastery of

When it comes to her makeup, in particular, we're in perpetual awe of the fact that she never seems to have an off day. It's truly unreal, and that's due in large part to her trusted makeup artist, Scott Barnes.

Two decades painting famous faces such as Beyoncé and Kim Kardashian West have taught Barnes a thing or two about getting the look right, every single time. So when we heard the veteran beauty guru was adding a range of face and eye palettes to his eponymous cosmetics line, we knew each offering would be something special. In an effort to get closer to our goal of putting our best faces forward, we jumped at the chance to ask Barnes his opinion on the makeup mistakes that are holding us back from looking like J.Lo (you know, aside from our pesky DNA).

Ahead, check out the five mistakes that make him cringe, and learn what to do instead.
