What Are the Benefits of Inulin for the Skin?

Inulin is a natural prebiotic fiber found in certain plants, such as chicory root. It hydrates the skin and rebalances the skin's microbiota. Learn more about its various effects when used on the skin here.

Inulin, but What Is It?

Inulin is named after the botanical genus "Inula", which includes the species elecampane (Inula helenium). This plant contains a lot of inulin of which it was first extracted at the beginning of the 19th century. However, the compound is found in numerous other plants (chicory, agave, garlic, asparagus, artichoke, Jerusalem artichoke, etc.), which use it for energy storage. Chemically, it is a linear polysaccharide consisting of glucose and fructose units.

The water-soluble inulin in cosmetics is usually obtained by extraction from chicory roots, followed by enzymatic hydrolysis, purification and subsequent drying by pulverization. Its I.N.C.I. name is "inulin" and it is often used in a concentration of 0.5 to 5  % in a cosmetic formulation.

Inulin is a "prebiotic", which means it is an ingredient that provides an excellent source of nutrients for the good bacteria on the surface of the skin.

Some Information About the Skin Microbiota

The microbiota thus refers to the totality of non-pathogenic microorganisms (bacteria, fungi, viruses, parasites), so-called commensals (bacteria useful to the organism), harbored in a specific environment, the microbiome. The human microbiota harbors millions of microorganisms. There are different microbiota in the organism: on the skin, in the mouth, in the vagina, in the male reproductive organs, in the lungs....

Thanks to their antimicrobial properties, these "good" bacteria enable the body to protect itself from and defend itself against invasive pathogens. In contrast, "bad" bacteria invade the body and can damage cells and/or cause inflammation. Nevertheless, they are also essential to our bodies as they stimulate our immune defenses. A healthy microbiota is the result of a balance between these "good" and "bad" bacteria. For example, overuse of antibacterial soaps can alter the skin microbiota, causing redness and/or irritation; this is called dysbiosis.

Note: The skin microbiota varies from person to person. It depends on age, lifestyle, gender, skin pH, etc.

Inulin, a Prebiotic To Rebalance the Skin Microbiota

As mentioned above, inulin is a prebiotic, i.e. a food for the "good" bacteria at the expense of unwanted microorganisms. When applied to the skin, it rebalances the microbiota and prevents dysbiosis. The microbiological barrier is strengthened, preventing the colonization of pathogenic microorganisms and thus the appearance of skin blemishes. The skin looks healthier and more even.

Inulin, a Moisturizing Agent for the Skin

Inulin is known for its moisturizing properties. This active ingredient is especially recommended for dehydrated skin. In fact, inulin is a sugar with film-forming properties that binds moisture and keeps it in the skin cells. The skin becomes more supple and soft, preventing feelings of tension.

Which Typology Skincare Products Contain Inulin?

Typology has developed several galenic products containing inulin, which you can find here:

Unifying and balancing complex with 3 pre- and probiotics rebalances the skin's ecosystem to prevent the appearance of blemishes and reduce redness. The skin is healthy and the complexion is even. It is suitable for all skin types, but is especially recommended for combination and oily skin prone to skin irregularities (redness, impurities).

The exfoliating cleansing gel with 5% PHA (INCI name: "Gluconolactone") and aloe vera (INCI name: "Aloe Barbadensis Leaf Juice Powder"), which provides gradual micro-exfoliation of the skin, and the cleansing gel with zinc PCA and bamboo extract (INCI name: "Phyllostachys Bambusoides Extract"), which rebalances the skin, also feature inulin in their formulation.

The botanical sprays are a mobile care that you can use at any time of the day. Three of them are enriched with inulin: the purifying botanical mist, the moisturizing botanical mist and the antioxidant botanical mist.
