We've seen our fair share of jaw-dropping special-effects Halloween makeup ideas [1] (*cough, cough* we're looking at you, bloody eyeliner [2]), but it looks like we just found the most armhair-raising one yet: "sliced" makeup. This intricate trend is like an optical illusion [3], as makeup artists highlight, shade, and paint on their faces to make them look as though they've actually been brutally chopped up by a deli meat carver. Some of them are so effing realistic, you may cringe a little.

We first spotted this trend after coming across creative genius Mimi Choi [4] on Instagram. Since she first started sharing her sliced makeup looks on social media, many other MUAs have followed suit, re-creating the trippy idea on their own. If you want to totally freak out your fellow Halloween [5] partygoers, read on to watch a sliced makeup tutorial, and see how Mimi and other crafty makeup mavens have mastered the spine-chilling trend.
