Probiotics, the living microorganisms often associated with gut health, are gaining popularity in the skincare space. Incorporating probiotics into a skincare routine may offer a variety of skin health benefits, especially for sensitive and problem-prone skin . This article explores the impact of probiotics on skin and how they can play a key role in a skincare routine .
The importance of the skin microbiota
The skin microbiota, often referred to as skin flora , is a complex ecosystem of microorganisms living on the surface of our skin. It plays a crucial role in the health and appearance of the skin. Here’s why the skin microbiota is so important:
1. Protection against infections
The skin microbiota acts as a protective barrier, preventing colonization by pathogenic microorganisms. Good bacteria on the skin, such as those of the genus Staphylococcus , produce antimicrobial substances that inhibit the growth of bad bacteria and other pathogens.
2. Strengthening the skin barrier
A balanced microbiota contributes to the fortification of the skin barrier. This barrier is essential to prevent transepidermal water loss and protect the skin from external aggressions such as pollution and chemicals.
3. Regulation of the immune system
The skin microbiota plays a key role in modulating the skin's immune system. It helps prevent excessive inflammatory responses that can lead to inflammatory skin conditions like eczema and psoriasis.
4. Prevention of inflammation and irritation
Beneficial microorganisms help maintain the balance of skin inflammation. An imbalance in the microbiota can lead to chronic inflammation, causing skin problems like acne, redness and irritation.
5. Influence on the pH balance of the skin
The skin microbiota helps maintain the skin's slightly acidic pH, which is essential for barrier function and to limit the growth of pathogenic microorganisms.
6. Production of nutrients and vitamins
Certain bacteria in the skin microbiota can synthesize essential vitamins and other nutrients that are beneficial to the skin, contributing to its radiance and overall health.
7. Impact on the appearance and aging of the skin
A healthy microbiome can help slow skin aging by reducing inflammation and strengthening the skin barrier. This can contribute to a more youthful appearance and improved skin texture.
8. Interdependence with the intestinal microbiota
The skin microbiota and the gut microbiota are interconnected. Gut health can influence skin health and vice versa. A balanced gut flora promotes healthy skin , while an imbalance can manifest itself as skin problems.
