It is also found in cosmetics like talcum and face powder to provide UVA protection and mask the presence of pores and blemishes. In the human body, zinc is a mineral that acts as an immune booster, and aids the body in maintaining sensory capabilities such as sight, taste, and smell. This is why zinc is often one the essential ingredients in cough and cold preventatives and multivitamins, as it has numerous benefits to the human body in the daily recommended doses.
