PREBIOTICS : Nourish your microbiota

SUPPORT | BALANCE | STRENGTHENS

What are prebiotics ?

Prebiotics are indigestible dietary fibers naturally present in certain foods (such as garlic, onion, leek, banana, or Jerusalem artichokes). Unlike probiotics, which are living microorganisms, prebiotics serve asfood with good bacteria(probiotics) of our intestinal microbiota.

They play an essential role in maintaining ahealthy intestinal balance, promoting the growth of beneficial bacteria, improving digestion, and contributing to better immunity. In cosmetics, they are also used tostrengthen the skin microbiome, this invisible layer of microorganisms which protects our skin from external aggressions.

Where do prebiotics come from ?

Prebiotics are naturally present in a wide variety of foods rich in soluble fiber, including root vegetables (Jerusalem artichoke, chicory, artichoke), fruits (unripe banana), legumes, and some whole grains. They often belong to the fructo-oligosaccharide (FOS), galacto-oligosaccharide (GOS), or inulin families.

In cosmetics, prebiotics are extracted from plants or produced by biotechnology. They are incorporated into skin care products tobalance the skin flora, soothe sensitive skin and strengthen natural defenses.

Properties and active ingredients

Prebiotics do not act directly like classic active ingredients, but exert aregulatory actionon the microbiota, whether intestinal or cutaneous. Here are their main characteristics:

• Stimulation of beneficial flora: They specifically feed good bacteria like bifidobacteria and lactobacilli.
• Strengthening the intestinal or skin barrier: By improving the flora, they strengthen protection against external attacks.
• Indirect anti-inflammatory effect: A balanced flora reduces the production of toxins and chronic inflammation.
• pH regulation: Promote an acidic environment conducive to protective bacteria, particularly on the skin.
• Reduction of digestive disorders: Bloating, disrupted transit, or intestinal inflammation.

What are the benefits of prebiotics ?

Whether for internal use (food, supplements) or external use (cosmetics), prebiotics arevaluable allies for overall health.

• Improved digestion: Support healthy transit, reduce bloating and prevent constipation.
• Strengthening the immune system: A balanced gut microbiota supports up to 70% of our immunity.
• Skin microbiome support: Soothes sensitive skin, prone to redness, or imbalances (acne, eczema).
• Radiance effect on the skin: In cosmetics, they promote healthier, better hydrated and naturally luminous skin.
• Infection prevention: Healthy flora is more resistant to pathogenic bacteria.

Their benefits:

• Nourish the good bacteria of the intestinal and skin microbiota.
• Strengthen the body's natural defenses.
• Improve digestion and digestive comfort.
• Soothe and rebalance sensitive skin.

How to consume or use prebiotics ?

In food:

• Integrated into a diet rich in fiber: garlic, leeks, onions, artichokes, Jerusalem artichokes, asparagus, legumes, unripe bananas, etc.
• In the form of food supplements (inulin, FOS, GOS) to actively support the intestinal microbiota.

In cosmetics:

• Balancing creams and serums: For skin prone to redness or acne.
• After-sun or restorative care: Help restore the skin's microbial balance.
• Gentle cleansers: Preserve the microbiome by avoiding overly harsh products.

Any side effects ?

Prebiotics are generallywell tolerated, but some side effects may appear, particularly in cases of overconsumption or sensitive intestines:

• Bloating and gas: Especially at the beginning of supplementation or a dietary change.
• Mild laxative effect: In case of excessive consumption of inulin or FOS.
• Skin reaction: Rarely, some very sensitive skin may react to a cosmetic formula containing prebiotics.

👉 If in doubt or regarding medical treatment, seek advice from a health or skin professional.

Prebiotics are recognized by the scientific community for theirbeneficial effects on the microbiota, digestion and immune health. Their role in cosmetics is supported by recent research that shows their ability torestore the skin microbiomeand improve the appearance of sensitive or unbalanced skin. They are an integral part of the“microbiome-friendly” trend, at the heart of new care formulations.
