Zinc is one of the essential minerals in the body due to the vital role it plays in gene expression, cell replication, and growth. However, it possesses skin healthy benefits that make it popular (51).

Zinc helps to fight acne, it protects the skin from aging, and it facilitates wound healing. It is also effective in lessening the formation of free radicals.

In the human body, more than 300 different enzyme reactions depend on zinc (52). This shows that most of the metabolic processes that take place in the body require zinc. Most of the cold lozenges and over-the-counter drugs can be used to increase the level of zinc in your body and improve the health of your skin, but dietary supplements are more effective and less risky.
