Of all the trace minerals needed for good health, two have particular value in reducing wrinkles. One is selenium. As an antioxidant, selenium neutralizes electron-hungry free radicals before they can damage skin cells. According to some sources, it also restores skin elasticity [source: Bauer].
The second mineral is copper. Copper is essential to the formation of collagen and elastin, those two important skin tissue proteins.
Like all trace minerals, these two are needed only in very small amounts. Good sources of selenium include tuna, salmon, Brazil nuts, eggs and whole grains such as brown rice, whole wheat and oats. You can find copper in legumes, beans and lentils, and nuts and shellfish.
