Zinc, a naturally occurring mineral, is often found in the earth’s crust and is extracted from various ores, such as sphalerite.
The history of zinc in cosmetic products dates back centuries. Ancient civilizations, such as the Egyptians and Greeks, utilized zinc compounds for their healing and protective properties. Zinc Oxide, in particular, has been a staple in skincare for its ability to provide a physical barrier against the sun’s harmful UV rays, long before the advent of modern sunscreens.
The process of making zinc for cosmetic use involves several steps. Initially, zinc ore is mined and then subjected to a series of chemical reactions to extract pure zinc. This pure zinc is then oxidized to produce Zinc Oxide, a fine white powder that is commonly used in various skincare and cosmetic products. The resulting compound is known for its stability and non-reactive nature, making it an ideal ingredient for a wide range of applications.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Zinc:
Zinc is celebrated for its antioxidant properties. In simple terms, antioxidants are like the bodyguards of your skin cells. They help to neutralize harmful free radicals, which are unstable molecules that can cause damage to your skin cells. This damage can lead to premature aging, wrinkles, and a dull complexion. By incorporating zinc into your skincare routine, you are essentially giving your skin an extra layer of protection against these environmental aggressors. This means healthier, more resilient skin that can better withstand the daily grind.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Zinc is generally considered safe for topical application in cosmetic products. However, like any ingredient, it can cause side effects in some individuals. Here are some potential side effects of using zinc topically:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of zinc during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing zinc.
Adverse reactions to zinc are relatively uncommon, but they can occur. To minimize the risk of an adverse reaction, it is recommended to conduct a patch test before widespread usage.
In terms of comedogenicity, zinc has a rating of 1 on a scale of 0 (totally non-comedogenic) to 5 (highly comedogenic). This low rating means that zinc is unlikely to clog pores and is generally suitable for people prone to acne, blemishes, or breakouts.
