Michaels' Instagram posts some truly stunning makeup, but she is really a fan of skin care. In one of her videos, she says, "I don't wear a lot of makeup, but I do wear a lot of makeup for when I want to have fun." Her most radical skin care treatment ""I've had quite a few extractions before, and those were the most painful things I've ever experienced. I wouldn't want to be my worst enemy.

Another of Michaels' regular skin care products is Augustinus Bader the Cream (open in new tab) moisturizer. She says, "It's a little expensive, but it really moisturizes my face." For her internal health, Michaels subscribes to Care/of (opens in new tab) daily vitamins. She also uses ice packs as part of her morning routine. I like to put it on in the morning when I'm swollen or hungover," she says. Or a hangover. It makes me look like I've had a good night's sleep, even though I only slept for 25 minutes."
