Zinc is a mineral and acts like a skin mechanic. It is found in skin care products and certain foods but can also be taken as a supplement to help care for your body from the inside out. It is most effective in cell renewal but also aids in collagen production, decreases free radical activity, helps prevent the growth of bacteria, repairs damaged tissue and reduces inflammation.
Zinc is helpful in treating acne and oily skin as it helps reduce the amount of oil and sebum produced by the skin. You may also find it in some sun protection products as Zinc Oxide.
