While there's no good time for a breakout, the worst ones seem to come at the most inopportune times -- like when you're a wedding guest and bound to see an old flame or two, or worse, when it's your own wedding and you wake up to a blossoming red boulder under your skin. It's on those days that we thank our lucky stars for full coverage makeup and those who wield makeup brushes like a magic wand to banish zits. Yep, we're talking about YouTube stars who have bared it all in the name of showing us how to really cover acne with makeup.

Usually, good lighting and a pro's touch keep acne from the public eye. But these YouTubers show what lies beneath layers of carefully applied primer, foundation, concealer and finishing powder. Watch these makeup wizards cast a vanishing spell on acne, from erasing the red marks that look like they're eating your face alive to disguising those 3-D bumps that seem to turn into their own planets.

A red spot can be particularly hard to cover when it's in the healing stage, especially if it's scabbing. For red and dark marks, none is more pro at creating a glowing, polished finish than YouTuber Desi Perkins. Her skill with concealer is truly astonishing -- even when it comes to crusty acne scabs. Here are her steps to the kind of glow that makes strangers gush over your skin.

Start by patting in alight, smooth, hydrating lotion. Desi uses Belif The True Cream Aqua Bomb, $22. Follow up by spot treating acne using a product like The Body Shop Tea Tree Oil, $10.

Give yourself all-over coverage with a foundation like Giorgio Armani Luminous Silk Foundation, $64, mixed with a highlighter like M.A.C. Strobe Cream, $33 for a glow-from-within look. Blend in with a BeautyBlender.

Taking the BeautyBlender, dab more of the highlighter-foundation mix onto the acne that is still shining through. Blend the edges for sheer coverage that doesn't look remotely cakey.
