It’s a term that we hear here and there but don’t always understand. What is the skin microbiome and why is it so important to take care of it? Let’s take stock.

The skin microbiome refers to the community of microorganisms living on the surface of human skin (on the skin barrier). It is a complex ecosystem consisting of bacteria, fungi, viruses, and other microorganisms that interact symbiotically with our skin...

What you need to know about the skin microbiome

1. Its composition: The skin microbiome is made up of billions of microorganisms. Bacteria (good bacteria and bad bacteria) are the most abundant, but fungi (such as yeast), viruses, and other microorganisms are also found. The species that make up the skin microbiome can vary from person to person.

2. Its functions: The skin microbiome performs several essential functions. It helps maintain the balance and health of the skin by forming a protective barrier against harmful microorganisms, regulating skin hydration, supporting the skin's immune system and participating in lipid metabolism. It ensures healthy skin!

3. Its balance: A balanced skin microbiome is important for skin health. When the microbiome is out of balance, it can lead to skin problems such as dry skin, atopic dermatitis (atopic eczema), irritation, skin infections, and inflammatory disorders like acne and other recurring blemishes.

4. Factors influencing the skin microbiome: The microbiome or skin flora can be influenced by various factors, including genetics, age, gender, personal hygiene, environment, diet, skin cosmetic products, external aggressions and medical treatments.

5. Skin Microbiome Care: To maintain a healthy skin microbiome, it is important to take gentle and balanced care of your skin. This includes using skin care products that are appropriate for your skin type, avoiding overuse of antibiotics or antibacterial products, maintaining good personal hygiene without disrupting the natural balance of the microbiome, and eating a balanced diet.

Skin microbiome research is constantly evolving. A better understanding of its role in skin health opens new avenues for personalized skin care and the management of previously unresolved skin conditions.

What is the difference between microbiome and microbiota?

You've probably heard of both terms before. Microbiome and microbiota are two closely related terms that refer to slightly different aspects.

The microbiome

The microbiome refers to the set of genes of microorganisms that live in a specific environment. It includes all the genes of bacteria, fungi, viruses, and other microorganisms present in that environment. Here, the skin microbiome, for example, refers to the set of genes of microorganisms that live on the surface of the skin.

The microbiota

The microbiota refers to the population of microorganisms themselves that live in a specific environment. These include bacteria, fungi, viruses, and other microorganisms that colonize that environment. Here, the skin microbiota refers to the specific microorganisms that live on the surface of the skin.

To put it simply, the microbiome refers to all the genes of microorganisms, while the microbiota refers to the microorganisms themselves!

How to properly maintain your skin microbiome?

As you will have understood, to promote skin it is better to maintain its skin microbiome. But how to do it?

Use gentle skincare products: Choose skincare products that are gentle and pH-friendly for sensitive facial and body skin . Avoid harsh cleansers and products that can disrupt the balance of the skin’s microbiome. Opt for gentle cleansers, non-irritating moisturizers, hydrating eye and face serums , and products without potentially disruptive ingredients.

Avoid overuse of topical antibiotics: Topical antibiotics may be necessary in some cases to treat specific skin conditions, but overuse can disrupt the skin microbiome. Use topical antibiotics only when recommended by a healthcare professional and follow their directions.

Avoid hot showers and long baths: Hot water and long baths can dry out your skin and disrupt the balance of your skin’s microbiome. Opt for lukewarm showers and short baths to minimize the impact on your skin.

Don’t forget about hydration: Maintaining good skin hydration is essential for its balance and health. Use a moisturizer that is appropriate for your skin type to maintain the skin barrier and help keep the microbiome balanced. Also remember to hydrate from the inside out by drinking enough water and eating foods that are rich in water.

Avoid harsh antibacterial products: Avoid overuse of harsh antibacterial products such as antibacterial soaps and hand sanitizers. These products can kill off the good, protective bacteria on your skin as well as the bad.

Eat a balanced diet: A healthy, balanced diet contributes to the health of your skin and skin microbiome. Consume foods rich in fiber, antioxidants, and essential nutrients to nourish your skin from the inside out.

Manage stress: Stress can impact your skin and skin microbiome. Try to find stress management techniques that work for you, such as meditation, yoga, deep breathing, regular exercise, or other relaxing activities.

By following these tips, you can help maintain a balanced skin microbiome and promote healthy skin. Remember, everyone is unique, so it's important to find a routine that works for your own skin and specific needs.
