The skin is made up of two proteins: collagen and elastin. These proteins work to keep the skin smooth and wrinkle free. Keeping these proteins healthy is what will also keep your skin looking great.
The sun is our first offender. It damages collagen, breaking down the structural fibers underneath the skin. Once the collagen is damaged, the skin will weaken, leading to sagging. Combine sun damage with the natural weakening of the skin that comes with aging, and wrinkles are an inevitable result.
Sugar increases the formation of AGEs, which damage collagen. Collagen fibers must remain linked together to help maintain the skin’s structure. Sugar damages the link between the collagen fibers, which is then exacerbated by exposure to UV light from the sun. The more collagen breaks down, the more wrinkled the skin will appear. In order to prevent wrinkles, reduce your sugar intake. High-sugar foods, such as candy, cake, or ice cream, should be eaten only occasionally — and not as part of your daily diet.
