Fucosyllactose, also known by its chemical name (2R,3R,4R,5R)-4-[(2S,3R,4S,5R,6R)-4,5-dihydroxy-6-(hydroxymethyl)-3-[(2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxyoxan-2-yl]oxy-2,3,5,6-tetrahydroxyhexanal, is a fascinating ingredient in the world of cosmetics. This compound is a type of oligosaccharide, which is a carbohydrate made up of a small number of simple sugars. Fucosyllactose is naturally found in human milk, where it plays a crucial role in the development of the infant gut microbiome and immune system.
In the cosmetic industry, fucosyllactose is primarily recognized for its skin conditioning and skin protecting properties. It is often listed under various names, including 2′-fucosyllactose or 2′-FL. The journey of fucosyllactose from a naturally occurring substance in human milk to a sought-after cosmetic ingredient is quite intriguing. Initially, its benefits were studied in the context of infant nutrition, but as research progressed, scientists discovered its potential applications in skincare.
The production of fucosyllactose for cosmetic use involves sophisticated biotechnological processes. It is typically synthesized using microbial fermentation, where genetically engineered bacteria are employed to produce the compound in large quantities. This method ensures a high purity level and makes it feasible to incorporate fucosyllactose into various skincare formulations. The end result is a versatile ingredient that can enhance the skin’s natural barrier, provide hydration, and offer protection against environmental stressors.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Fucosyllactose:
Fucosyllactose is known for its skin conditioning properties. This means it helps to maintain the skin in good condition. When applied in cosmetic formulations, it works to keep your skin feeling soft, smooth, and hydrated. Essentially, it acts as a moisturizer that can help improve the overall texture and appearance of your skin, making it look healthier and more vibrant.
Another significant benefit of Fucosyllactose is its skin protecting function. This involves creating a barrier on the skin’s surface to shield it from environmental stressors such as pollution, harsh weather, and other external factors that can cause damage. By forming this protective layer, Fucosyllactose helps to prevent moisture loss and keeps the skin resilient against potential irritants, thereby maintaining its integrity and 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).
Fucosyllactose is generally considered safe for topical application, with a low potential for causing adverse reactions. However, as with any cosmetic ingredient, there are some potential side effects to be aware of:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of fucosyllactose 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 this ingredient.
Side effects and adverse reactions from fucosyllactose 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.
Fucosyllactose has a comedogenic rating of 0, meaning it is non-comedogenic. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
