Zinc is a mineral best known for its immune enhancing properties. With specific reference to skin health, zinc influences protein synthesis and related biological processes which encourages skin tissue regeneration. Several studies indicate that zinc is as effective as some antibiotics in acne therapy.

It is likely that zinc’s benefits in acne are not only due to tissue regeneration and healing but also due to its influence on hormones, retinal-binding protein and its ability to enhance the manufacture of anti-inflammatory compounds within the body. However, poorly absorbed forms of zinc have little or no influence on acne when compared to the better forms such as zinc citrate. It should also be noted that long term use of zinc is liable to interfere with copper utilisation as well as iron absorption. When taken on an empty stomach, even moderate doses of zinc can cause nausea.
