Birdies Cofounders Bianca Gates and Marisa Sharkey Share Their Must Haves

After experiencing severe acne growing up, Gates takes her skin-care routine seriously and invests in products that make her skin feel good. Her nighttime skin-care routine consists of an eye cream, a neck cream, and the Biologique Recherche Crème Biofixine ($338). As someone with a drier skin type, she likes that this moisturizer deeply hydrates the skin rather than sitting on top of the skin. "It really penetrates into the pores, and you feel it moisturizing from the in out. You just get that dewiness, and you feel like it's going to work. The little worker bees in the moisturizer just go to work and just plump up and moisturize the skin. When you wake up in the morning, you feel clean and fresh," she says.
