Skin reflects internal health. The most studied nutritional supports for aging skin are polyphenols, omega-3s, and adequate protein.
Eat the rainbow
Berries, tomatoes, leafy greens, and pomegranate supply polyphenols that protect collagen from oxidative damage.
Healthy fats
Olive oil, walnuts, and fatty fish supply omega-3s and vitamin E for skin resilience.
Hydration and sleep
Skin repairs deepest at night; chronic sleep loss visibly accelerates skin aging.
Limit
Ultra-processed foods, excess sugar, and frequent alcohol all impair collagen and accelerate skin aging.
