Formula IngredientPrebiotic, HumectantInulin
INCI: Inulin
Inulin is a naturally occurring fructose polysaccharide (complex carbohydrate) derived from the roots of plants such as chicory, Jerusalem artichoke, and dahlia. As a prebiotic, it selectively feeds beneficial bacteria on the skin — particularly Staphylococcus epidermidis — helping to balance the skin microbiome and crowd out pathogenic species. It also acts as a humectant, forming a thin flexible film on the skin surface that draws in moisture and reduces trans-epidermal water loss.

Is Inulin safe? Key considerations
Can Inulin cause irritation?
Low RiskInulin is well-established as non-irritating at cosmetic concentrations (0.5–3%). Research published in peer-reviewed cosmetic science journals found that inulin at 5 mg/mL does not exhibit skin irritation activity and can actually reduce the irritation potential of wash-off formulations. No EU CosIng Annex II or III restrictions apply. Isolated allergic reactions are rare and are more commonly attributed to other formulation components rather than inulin itself.
Does Inulin increase sun sensitivity?
No RiskInulin does not increase photosensitivity. No sun protection precautions are required based on its presence in a formulation. Its antioxidant properties may offer minor protection against free radical damage from UV exposure.
Is Inulin safe during pregnancy?
CautionNo known contraindications for topical inulin during pregnancy or breastfeeding have been identified, and it is a naturally derived plant-based polysaccharide with a strong safety record. However, as noted by Typology and cosmetic safety assessors, the available data specifically addressing topical use in pregnant and breastfeeding women is insufficient to make a definitive safety statement. Consult a healthcare provider before use during pregnancy as a precaution.
How does Inulin work?
Inulin is a naturally occurring fructose polysaccharide (complex carbohydrate) derived from the roots of plants such as chicory, Jerusalem artichoke, and dahlia.

Individuals with known inulin or chicory allergy (rare) should review the considerations above before use.
