Today, there is a lot of talk about probiotics… but not just for digestion. These beneficial microorganisms also play a major role in our skin. The skin microbiome, this ecosystem of bacteria and microorganisms living naturally on the surface of the skin, directly influences its health, radiance, and ability to defend itself against external aggressions.

 

The skin microbiome: what is it?

The skin microbiome is composed of billions of microorganisms living naturally on the skin: bacteria, yeasts, and fungi.
Contrary to what one might think, these microorganisms are not “dirty” or harmful: they protect the skin, regulate its pH, and contribute to healing and defense against external aggressions.

A balanced microbiome allows for:

• A strengthened skin barrier, more resistant to irritation.

• A soothed skin, less prone to redness and inflammation.

• A radiant appearance and an even complexion.

Conversely, an unbalanced microbiome can cause: tightness, dryness, blemishes, eczema, and premature aging.

 

Probiotics, prebiotics, and postbiotics: how they help the skin

To preserve and strengthen the microbiome, cosmetic products now incorporate three types of active ingredients:

1. Probiotics
   These are living microorganisms applied directly to the skin to restore a natural balance. They help calm inflammation, limit blemishes, and strengthen the skin barrier.

2. Prebiotics
   These are ingredients that nourish the “good bacteria” already present on the skin, allowing the microbiome to regenerate naturally.

3. Postbiotics
   These are substances produced by beneficial bacteria (vitamins, enzymes, fatty acids). They have an immediate soothing, moisturizing, and protective effect, even without the presence of living bacteria.

 

Probiotic-rich foods for healthy skin

Certain fermented foods are particularly beneficial for the skin microbiome. Here are a few examples:

• Plain yogurt: Rich in Lactobacillus and Bifidobacterium strains, it supports intestinal and skin flora.

• Kefir: A fermented drink containing a variety of beneficial bacteria and yeasts.

• Unpasteurized sauerkraut: Contains lactic acid bacteria that promote a balanced microbiome.

• Kimchi: A Korean fermented dish rich in probiotics.

• Miso: Used in Asian cuisine, it provides beneficial microorganisms.

• Tempeh: A fermented soy-based product, rich in protein and probiotics.

• Kombucha: A fermented tea-based drink, rich in probiotics.

Incorporating these foods into your diet can help maintain a balanced skin microbiome, which is essential for healthy, radiant skin.

The effects on skin and daily life

Incorporating probiotics into a beauty routine allows for:

• A stronger skin barrier, therefore less tightness and redness.

• A reduction in blemishes and clearer skin.

• Improved texture and radiance, even for sensitive skin.

• Protection against oxidative stress, pollution, and external aggressions.

And when combined with an optimal sleep environment (silk pillowcases, soft masks), these active ingredients become even more effective: night is the ideal time for the regeneration of the microbiome, the skin, and the mind.
