Soy isoflavones are naturally occurring compounds found in soybeans, also known by their scientific name Glycine max. These compounds are a type of phytoestrogen, which means they are plant-derived molecules that can mimic the action of estrogen in the body. In the context of cosmetics, soy isoflavones are primarily used for their skin conditioning properties, helping to improve the appearance and feel of the skin.
The history of soy isoflavones in cosmetics is relatively recent, although soybeans themselves have been cultivated for thousands of years, primarily in East Asia. Initially, soy was valued for its nutritional benefits, but as scientific research progressed, the potential of soy isoflavones in skincare began to be explored. Researchers discovered that these compounds could help in maintaining skin elasticity, reducing the appearance of fine lines, and providing overall skin rejuvenation.
The process of extracting soy isoflavones for cosmetic use involves several steps. First, soybeans are harvested and cleaned to remove any impurities. The beans are then processed to extract the soy protein, which is further refined to isolate the isoflavones. This extraction process often involves the use of solvents or other chemical methods to ensure a high concentration of isoflavones is obtained. Once isolated, the soy isoflavones are purified and prepared for incorporation into various cosmetic formulations, such as creams, serums, and lotions.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Soy Isoflavones:
Soy Isoflavones are primarily known for their skin conditioning properties. This means that they help to maintain the skin in good condition. In practical terms, this can translate to a variety of benefits such as improved skin texture, enhanced smoothness, and a more even skin tone. By conditioning the skin, Soy Isoflavones can help it look healthier and more vibrant, making it a popular ingredient in many skincare products.
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).
Soy Isoflavones are 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 Soy Isoflavones during pregnancy are lacking. Therefore, it is recommended that they consult a healthcare professional for further advice.
Adverse reactions to Soy Isoflavones are relatively uncommon, but it is always wise to perform a patch test before widespread usage to ensure there is no sensitivity or allergic reaction.
On a comedogenicity scale of 0 to 5, Soy Isoflavones are rated as 1, meaning they have a low likelihood of clogging pores. This makes them generally suitable for individuals prone to acne, blemishes, or breakouts.
