Following the pencil challenge we’re feeling unstoppable. This time we have another test and it’s not for the faint hearted. You’ll probably require sunglasses to look at some of these images, because the latest online fashion is to apply makeup using only highlighters. Yes, you’ve understood correctly. The full face using only highlighters challenge consists of trying to apply makeup using only products with very high light refraction. Certainly the final result is debatable, halfway between Casper (the friendly ghost) and a glazed donut, but in the end what matters is having fun while taking this crazy challenge. In this case we can skip the step-by-step tutorial, but we can tell you what we learned from the challenge in question. First: highlighter is much less scary than we thought. Used sparingly it really sets off your complexion. Second: it is truly a multitasking product; you can turn it into an eyeshadow, blusher, highlight features and also improve the tone of any foundation. Last, but not least this YouTube challenge is a perfect way to discover many shades of highlighters and see what kind of results they have on the face. We added our 15 favorites to the gallery, some of them are limited edition… so don’t miss out!
