Bienfaits inuline pour la peau.

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 microbiota. Discover in detail its various actions when applied topically.

Inulin, what exactly is it?

Theinulin derives its name from the botanical genus "Inula", to which the species Elecampane (Inula helenium) belongs, which contains a high amount of it and from which it was first extracted in the early 19th century. However, this compound is present in many plants (chicory, agave, garlic, asparagus, artichoke, Jerusalem artichoke, etc...) that use it to store energy. Chemically, it is a linear polysaccharide composed of glucose and fructose units.

Water-soluble, the inulin found in cosmetic care is typically obtained through extraction from chicory roots, followed by enzymatic hydrolysis and purification, then spray drying. Its I.N.C.I. name is "Inulin" and it is generally introduced at a concentration of 0.5 to 5% in a cosmetic formula.

Inulin is a "prebiotic", that is, an ingredient that serves as an excellent source of nutrition for the beneficial bacteria present on the skin's surface.

A few reminders about the skin microbiome.

The term microbiota refers to thecollection of non-pathogenic microorganisms (bacteria, fungi, viruses, parasites), known as commensals(bacteria that are beneficial to the body), housed in a specific environment, the microbiome. The human microbiota harbors millions of microorganisms. Within the body, there are different microbiotas: on the skin, in the mouth, in the vagina, in the male sexual organs, in the lungs...

Thanks to their antimicrobial properties, these "good" bacteria enable the body to protect and defend itself against invasive pathogens. Conversely, the "bad" bacteria invade the body and can damage cells and/or induce inflammation. However, they are also essential to our body, as they stimulate our immune defenses. A healthy microbiota results from a balance between these "good" and "bad" bacteria. For instance, excessive use of antibacterial soaps can disrupt the skin microbiota, which can lead to redness and/or irritation; this is referred to as dysbiosis.

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

Inulin, a prebiotic for rebalancing the skin microbiota.

As previously mentioned, theinulin is a prebiotic, which is a food for the "good" bacteria, at the expense of undesirable 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 imperfections. The skin becomes healthier and more uniform.

Inulin, a hydrating agent for the skin.

Theinulin is recognized for its moisturizing properties. This active ingredient is particularly recommended for dehydrated skin. Indeed, inulin is a sugar with film-forming properties that captures moisture and retains it in the skin cells. The skin becomes more supple and soft, preventing tightness.
