Zeaxanthin is a naturally occurring carotenoid alcohol that is often found in conjunction with lutein. It is commonly sourced from green leafy vegetables like spinach and kale, as well as from yellow and orange fruits such as corn and peppers. In the world of cosmetics, it is sometimes referred to by its INCI name, Zeaxanthin, but you might also see it labeled as E161h in some contexts.
The history of zeaxanthin in cosmetic products is relatively recent, although its beneficial properties have been known for much longer, particularly in the field of nutrition. Initially recognized for its role in eye health, scientists began to explore its antioxidant properties, which led to its inclusion in skincare formulations. The journey from dietary supplement to skincare ingredient was driven by the growing understanding of how antioxidants can combat oxidative stress and aging in the skin.
Zeaxanthin is typically produced through either natural extraction or synthetic processes. Natural extraction involves isolating the compound from plant sources, which is a labor-intensive but highly effective method. On the other hand, synthetic production involves chemical synthesis in a lab, which can offer higher purity and consistency. Both methods aim to deliver a potent antioxidant that can help protect the skin from environmental damage.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Zeaxanthin:
Zeaxanthin is primarily known for its antioxidant properties. In the world of cosmetics, antioxidants are crucial because they help protect the skin from oxidative stress caused by free radicals. Free radicals are unstable molecules that can damage skin cells, leading to premature aging, dullness, and other skin issues. By neutralizing these free radicals, Zeaxanthin helps maintain the skin’s youthful appearance and overall health.
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).
Zeaxanthin is generally considered safe for topical application in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of zeaxanthin during pregnancy are lacking. Therefore, it is advisable for pregnant or breastfeeding women to consult a healthcare professional for further advice before using products containing this ingredient.
Side effects and adverse reactions from zeaxanthin are generally uncommon. However, it is always recommended to perform a patch test before widespread usage to ensure that your skin does not react negatively to the ingredient.
Zeaxanthin has a comedogenic rating of 0, meaning it is considered non-comedogenic. This makes it a suitable option for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores.
