The singer and rapper Lizzo, 31, is one of the buzziest acts in music right now, what with her fierce lyrics, outspoken personality and fashion presence. She is also about to cross over into film, with a role in “Hustlers,” out Sept. 13. Lizzo, who is an Urban Decay brand ambassador, lives in Los Angeles. Here, she dishes on her skin rehab, impossible standards and what she does first thing in the morning.

On Waking Up

I’m real bizarre, but I believe in water first thing. Water is really important for face and hair. I go to the bathroom and, believe or not, hit myself with some Evian spray to the face.

Out of Skin Rehab

So I was on the road, and I was sleeping in my makeup a bunch. It was so embarrassing. What am I, a child? And I was waking up and thinking I’m invincible, nothing can happen to me! Then one day my face broke out — not even broke out in acne, but red and irritated. I was like, “Oh my God, this is what happens when you party all night and you don’t wash off your makeup.”

I went through skin rehab. Listen, I was in face masks — the Peter Thomas Roth green tea face mask, literally every night. It was really scary. I thought my skin would never come back. I told my makeup artist, Alexx Mayo: I really have to get serious about my skin care, and he introduced me to the Sunday Riley products.
