Vitamin C is essential for collagen production, the protein that keeps your skin firm, smooth, and youthful. It’s also a powerful antioxidant, protecting your skin from free radical damage caused by pollution, stress, and UV exposure.
Where to get it: Citrus fruits, berries, kiwi, broccoli, kale, and superfood blends like GRNS, which includes blueberry, cranberry, and other vitamin C-rich fruits.
