There are more than 8 billion people on the planet, in all different shapes and colors. But scrolling through curated Insta feeds or watching the streaming show du jour, it can feel like everyone looks the same. And that's a major bummer. "When only a narrow type of beauty is consistently represented, society begins to view anything outside that 'standard' as undesirable," University of Florida advertising professor Robyn Goodman, Ph.D., tells Us. Seeing an A-lister buck those beauty tropes can be a huge morale boost for the rest of us, says Virgie Tovar, a body image expert and host of the GLP-1 Truth Serum podcast. "Watching someone who looks like you portrayed with confidence and glamour tells you that you belong exactly as you are," she says. That's easier said than done, even for celebrities who encounter the same pressures to be pretty in prescribed ways. Redefining Beauty: Stars Paving the Way for a New Era of Self-Confidence "Showing up confident in your own body can be hard," says Amy Harman, LMFT, CEDS-S and author of Perfectly Imperfect, "but it's truly an accomplishment." Here are some of the stars doing just that: Difference Can Be a Superpower Cedric Ribeiro/Getty Images for Atlantis The Royal/ Dolce&Gabbana x Ounass As a contestant on America's Next Top Model in 2014, Winnie Harlow was a fan favorite because of her unique looks. But growing up in Canada, the supermodel, now 31, was ruthlessly teased for her unusual skin pigmentation caused by vitiligo. "I often felt misunderstood," Harlow shared in a November social media post announcing her forthcoming children's book, Simply Winnie, which tells the story of her childhood. "I wrote this book for any child who feels different, to remind them not only are they not alone, they're seen! I want children to grow up in a world... where 'the ugly duckling' is rewritten simply as 'The Beautiful Swan.'" Harlow is working to make that happen, gracing the covers of top fashion mags and appearing in campaigns from Fendi to Victoria's Secret; she even has her own beauty line, Cay Skin. "We all have differences, but we are not defined by them," she said. "We are a beautiful blend of all the things that make us, us." BEAUTY SCHOOL LESSON: "Owning your differences is a type of superpower," Tovar tells Us. "I always remind people: Don't ever let an external source tell you how you're supposed to look." Don't Forget Your Roots Angel Delgado/Getty Images Nigerian-British actress Wunmi Mosaku's work in Sinners has made her an Oscar front-runner. But with dark skin and a curvaceous figure, Mosaku, 39, once thought a film career wasn't in the cards. "Theater was going to be my route because I look how I look," she's said. "I didn't see me represented so much on screen at that time." A large part of discovering her own beauty came from looking back at her lineage. Mosaku said her mother would note familial traits, such as a gap between her front teeth, and tell her, "Well, I have a little gap and your dad has a little gap and grandma has a little gap. So what do you think of us?" "And I'm like, Oh yeah... I do think you're beautiful," she recalled. Mosaku now proudly shows off her roots, often donning outfits by little-known Nigerian designers. "I wanted to feel like I was supporting the people who don't always feel seen in the fashion industry," she explained. BEAUTY SCHOOL LESSON: "Wunmi is an excellent example of embracing your body by honoring where you came from," says Harman. "I love that she's highlighting designers from non-traditional backgrounds. We need more people showing up as they are, accepting their genetics, and moving forward confidently." Your Body, Your Business Amy Sussman/Getty Images For Ariana Grande, being pop-u-lar comes with a downside. While the Grammy winner, 32, wants audiences to focus on her enchanting performance in Wicked: For Good, online trolls can't stop yapping about her weight, claiming she looks "frail." For Grande, who got her start on Broadway when she was just a teen, it's sadly the norm. "I've been kind of doing this in front of the public... since I was 16 or 17," she said. "I've heard every version of it - of what's wrong with me." While it's taken a while, the singer has learned to tune out "the noise" of shamers. "I'm really lucky to have the support system that I have," she said. "And to just know and trust that I'm beautiful." BEAUTY SCHOOL LESSON: Strangers don't get to weigh in on your weight. "We should be gentler and less comfortable commenting on peoples' bodies," Grande has said, adding that individuals should try their best to ignore unwanted comments. "You keep yourself safe. Cause no one has the right to say s**t."
