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.

To make any lingering hint of a blemish disappear, use a hydrating concealer like Becca Aqua Luminous Perfecting Concealer, $30. Perkins uses the same foundation brush to tap over the breakouts and feather the edges, then sets the makeup with a finishing powder.

After faking flawless, luminous skin, Perkins goes on to show how to make your entire face glow like you're taking sips from the fountain of youth. One pro tip from Perkins: Don't apply highlighter where you have a breakout. It will only attract attention to the area.

It's one thing to hide redness; it's quite another to disguise pitted, scarred acne marks. Doing so requires faking the texture of your skin. YouTuber Leyla Rose uses not one, not two, but three priming products underneath her foundation to minimize scarring: The Body Shop Vitamin E Moisture Cream, $12, Too Faced Hangover Primer, $15, and Too Faced Primed and Poreless, $30.

Sometimes acne rears its ugly head all over your face. Sigh. It happens. Queen contourer Heidi Hamoud shows us how to deal when your whole face is permanently aflame.

After applying moisturizer (Hamoud uses Charlotte Tilbury Magic Cream, $100), apply a mattifying primer like Make Up For Ever Step 1 Skin Equalizer, $37, to "create a shield" over the acne. Then, Hamoud relies on a makeup pro trick to camouflage redness: She pulls out the green stuff. Because green counteracts redness, tapping a product like Becca Backlight Targeted Colour Corrector, $30, in Pistachio over acne makes the red spots blend seamlessly into the skin under foundation. Blend the green with a damp BeautyBlender, pushing it into the skin.
