The oil/moisturizer + eye makeup problem—it’s a thing,for certain. Even if you consume the most toxic waterproof eyeshadows and mascaras, face oils and moisturizers are going to melt them, and to some degree. Weirdly,I get less smudging from the Juice Mascara than any—any—conventional one. But even without face oil or moisturizer, the oils naturally present in your skin will eventually cause most eye makeup to smudge/flake/drip/fade.
