Camila Mendes's Must Haves: From $25 Undereye Masks to Her Favorite Prada Bag

Mendes says that she can't go about her day without first having her AG1 ($79), a super-greens powder supplement.

"It's the first thing I drink every morning," she says. Mendes explains that her approach to wellness and beauty is intertwined. "I think the Brazilian women in my family have had a huge impact on my relationship with beauty. They believe in beauty as a product of health and well-being, and I think because of that, my relationship with beauty has always been centered around nutrition, fitness, and wellness. I think true beauty starts from the inside and works its way out."

Pro Tip: One scoop of AG1 is packed with vitamin C, vitamin B complex, probiotics, and essentially all the vitamins you'd normally find in a multivitamin.
