This smoothie bowl's beautifying properties come from more than just antioxidant-rich berries—flavorless, hydrolyzed collagen powder is high in amino acids that promote skin elasticity and repair. Avocado keeps skin dewy and soft, thanks to unsaturated fatty acids, and its high lutein content may also protect skin from UV radiation and inflammatory stress. Lemon provides abundant vitamin C and neutralizes free radicals that can damage skin cells.Get the recipe.
