Older Skin Has DNA Damage

While it is quite common for our cells to sustain some DNA damage over the course of time, our skin cells take the brunt of this damage, since these cells are routinely exposed to solar radiation. In fact, when you get a sunburn, thousands of skin cells have been killed. The cells that survive often have DNA damage. Unfortunately, as we age, our bodies produce less DNA and RNA material, so our cells lose their ability to repair DNA damage—all of which promotes wrinkles, lines, and sagging.
