Fructooligosaccharides (FOS) are a type of carbohydrate derived from plants, often found in fruits and vegetables. In skincare, they act as prebiotics, supporting the growth of beneficial microorganisms on the skin's surface. They also function as humectants, helping to attract and retain moisture, contributing to skin hydration and a healthy barrier.

Fructooligosaccharides (FOS) are natural prebiotics, a type of sugar molecule found in many plants. They serve as food for beneficial bacteria, both in the gut and on the skin.
How do Fructooligosaccharides benefit the skin?
On the skin, FOS help to nourish the skin's natural microbiome, promoting a healthy balance of bacteria. They also act as humectants, drawing moisture into the skin to keep it hydrated and support the skin barrier.
