FunctionPrebiotic

What it is — Fructooligosaccharides (INCI: Fructooligosaccharides) are plant-derived prebiotic sugars.

What it does — They are commonly used to support a balanced-feeling skin microbiome and to help hydrate and soothe.

Typical use — They appear in essences, serums, creams and masks, often in barrier- or microbiome-focused formulas as a supporting ingredient.

Who it suits / good to know — Suitable for most skin types and often chosen for gentle, comfort-focused routines. Prebiotics are used for supportive conditioning rather than as a treatment.

Safety — DHALIORA grades it low risk: a gentle prebiotic humectant. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk — gentle prebiotic humectant.
How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
