Soy

Isoflavones, which are antioxidant chemicals found in soy, may have a role in reducing the appearance of skin aging. As a result, including soy-rich foods like tofu and soy milk in your diet might help reduce the appearance of dullness and wrinkles, resulting in a smoother, more youthful appearance. In one small study, consuming soy isoflavones every day for 8–12 weeks reduced fine wrinkles and increased skin elasticity in middle-aged women.

Soy may also help maintain your skin smooth and strong in postmenopausal women by reducing skin dryness and increasing collagen levels. These isoflavones not only protect your body's cells from harm but also your skin from UV radiation, effectively reducing your risk of skin cancer.
