Oranges are healthy for your skin for two major reasons: they're rich with vitamin C and have a ton of water. Vitamin C, while also being an antioxidant, is important for the formation of collagen, while water moisturizes the skin from the inside out and helps to prevent breakouts. In order to prevent sagging skin and wrinkles, collagen keeps the skin tight and elastic.
Pomegranates
This fruit is abundant in skin-friendly vitamin C, just like oranges. Pomegranates also include punicalagin and ellagic acid. Punicalagin is thought to improve your body's ability to protect collagen, and ellagic acid reduces collagen degradation while fighting free radical damage. When you combine it with vitamin C's ability to increase collagen, your skin will greatly benefit.
