Aguilera looks amazing, and she tells People that it's all natural. Aguilera says that she avoids Botox and other surgeries. "We like expression, especially in my line of work," she explained. "I don't want to have a frozen face. Whether it's being on-camera or performing onstage, I have to stay authentic to my emotion."

Aguilera tells People that she's comfortable with herself, and that she's actively built this confidence. "I've seen myself go through different stages of my life and complain about certain things. As I've gotten older, I look back, and I'm like, 'God, every stage is a new era.' I'm really into feeling more self-assured as you get older. That's the thing to truly embrace. It's harmful when [aging] becomes an obsession."

Aguilera has amazing skin, and shared some of her secrets with Allure. She says that she likes to keep her routine simple. "I do not fuss with a 50-step beauty baloney routine. It's just not for me. For some people that might work, and they might like the experience of the whole thing. I'm a mama. I mean, I'd rather be in my bed on my time off playing Nintendo Switch."

Aguilera tells Allure that she is working on avoiding society's beauty standards. "It's a lot of stigma, a lot of old-school behavior and ideals that women have to look a certain way and that it's shameful to get older. I've grown up in this business. I started performing at six or seven and then I broke when I was a teenager. No matter what you do, you're going to have people that hate on you. The bigger you are and the more successful, unfortunately, that comes with more hate or more scrutiny. And I'm a very sensitive person, but I'm also very tough at the end of the day."

Aguilera's biggest skincare secret is keeping her skin moisturized. She tells Marie Claire, "Sometimes I wash my face the first thing in the morning, sometimes I do not. But moisture is going on no matter what. My skin tends to naturally lean to the drier side—always has. And so depending on what climates I'm traveling to, or how many planes I'm on, it can be crazy dry."

Aguilera shared some of her favorite workouts in her Marie Claire interview. She says that she doesn't like to put pressure on herself when it comes to fitness, and that she does workouts she enjoys. "I like to do things that make me feel good mentally when I work out. I don't like to feel isolated or secluded. If I'm in front of a mirror doing weights, I feel like I'm in rehearsal and it's work. I like to get out of my head."

One of Aguilera's favorite workouts to do to stay in shape is outdoor yoga. "I love fresh air, so I prefer hikes when I can get into nature," she tells Marie Claire. "I love doing yoga outside. Yoga was a big game changer. My life has always been very fast paced and on the go, so yoga really allowed me to stop the clock and slow down mentally. It lets me breathe into my body, stretch, and get into stagnant energy."
