This little blue fruit is an antioxidant powerhouse: It’s got ample amounts of vitamin C, plus phytonutrients called anythocyanidins (which are found in the berries’ blue pigment). Besides their antioxidant benefits, blueberries may inhibit collagen breakdown, says Valori Treloar, M.D., an integrative dermatologist in Newton, Mass. In one study, subjects who applied blueberry extract to their skin showed an increase in skin thickness and moisture, as well as an improvement in fine lines.

The isoflavones in soy are potent antioxidants that reduce free radical damage and promote the growth of new, skin-plumping collagen. “There’s evidence that the natural estrogens in soy improve skin thickness,” says Alexiades- Armenakas. There is also good science behind the use of soy to reduce age spots. The soy proteins help even out skin tone to reduce the appearance of existing spots—and may even prevent new spots from popping up. “Soy blocks the receptors in the skin cells so that pigment can’t move from the melanocytes—where the pigment is produced—into the cells,” says Baumann.
