What Inulin does

Holds water on the skin
Adds a soft, smooth feel
Adds body to the formula

Inulin is found naturally in many plants, including chicory root, agave and Jerusalem artichoke. It is extracted from these plants and purified for use in personal care. Food makers also use it as a fiber.

Formulators use inulin because it attracts and holds water, which helps skin feel softer and more comfortable. It can also add a smooth, slightly cushiony feel without greasiness. In deodorants and cleansers, it often helps give texture and a pleasant feel, and it is generally well tolerated.

Frequently asked questions

Is inulin the same as insulin?

No. The names sound alike, but they are unrelated. Inulin is a plant carbohydrate used in skincare and food. Insulin is a hormone the body makes. The two do not work the same way.

Is inulin good for dry skin?

It can help. Inulin holds water in the outer layer of skin, which can make dry-feeling skin feel more comfortable. It is often part of moisturizers that also contain other hydrating ingredients.
