Dramatic reversal of skin aging has been seen in smokers who stopped for at least nine months. This does not mean, however, non-smokers will not also experience similar improvements by eliminating avoidable chemical exposures, detoxifying, as well as changing their diet to include longevity-promoting nutrients and phytocompounds, such as blueberry, zinc, and chocolate. In fact, a wide range of natural substances have been studied to contribute to restoring youthfulness, elasticity and health to the skin, as you shall soon see.
