Fructooligosaccharides

Description

Fructooligosaccharides (FOS) are prebiotic carbohydrates that have gained significant attention in skincare formulations due to their ability to support the skin's microbiome. These short-chain oligosaccharides are composed of fructose units linked by β-(2→1) glycosidic bonds, typically derived from natural sources such as chicory root or synthesized enzymatically.

In skincare, FOS act as a food source for beneficial bacteria on the skin's surface, promoting a balanced and diverse microbiome. This balance is crucial for maintaining skin health, barrier function, and overall complexion. FOS have been shown to enhance the growth of probiotic strains like Lactobacillus and Bifidobacterium, which can help combat pathogenic microorganisms and reduce skin inflammation.

Additionally, FOS exhibit humectant properties, attracting and retaining moisture in the skin. This hydrating effect can improve skin texture, reduce the appearance of fine lines, and enhance overall skin suppleness. Some studies suggest that FOS may also have antioxidant properties, potentially protecting the skin from oxidative stress and environmental damage.

When formulating with FOS, it's important to consider their stability in various pH ranges and their compatibility with other skincare ingredients. Typically, FOS are well-tolerated and can be incorporated into a wide range of skincare products, including serums, moisturizers, and masks.
