The skin is our body's first line of defense against external aggressors. Its protective function depends largely on the health of the skin barrier. But do we really know what it is, how it works, and why it's so important to maintain its balance?
What is the skin barrier?
The skin barrier is the outermost layer of the skin, located in the epidermis. Its main function is to act as a protective shield, preventing the entry of harmful agents such as bacteria, viruses, and pollutants, while also preventing excessive loss of water and essential nutrients. 
To understand its importance, let's imagine a brick wall where skin cells act as the building blocks and lipids (natural fats) act as the cement that binds them together. When this wall is intact, the skin appears healthy, radiant, and balanced. However, if the structure weakens, problems such as dryness, sensitivity, inflammation, and even conditions like acne or dermatitis can arise.
What factors weaken the skin barrier?
There are multiple factors that can alter the balance of the skin barrier:
- Using harsh products : Harsh chemical exfoliants, sulfate cleansers, and overuse of acids can weaken the skin's protective layer.
- Environmental factors : Pollution, sun, cold and sudden changes in temperature can affect the stability of the skin barrier.
- Stress and lifestyle : Chronic stress, lack of sleep, and a nutrient-poor diet can all impact skin health.
- Aging : As we age, lipid production decreases, making the skin more vulnerable to dehydration and irritation.
What is the role of the microbiome in skin health?
Millions of beneficial microorganisms, known as the skin microbiome, live on the skin's surface. These "good" bacteria help maintain skin balance, preventing the growth of harmful bacteria and reducing inflammation.
When the skin barrier is weakened, this balance is disrupted, leading to problems such as acne, sensitivity, and inflammation. This is where probiotics and prebiotics play a key role in skin recovery and strengthening.
Probiotics and prebiotics: allies for a strong skin barrier
Probiotics are live microorganisms that, when consumed in adequate amounts, provide health benefits. For skin, certain probiotics help:
- Regulate inflammation and reduce skin sensitivity.
- Control the growth of bacteria that can cause acne or irritations.
- Strengthen the skin barrier, improving its protective function.
Prebiotics, on the other hand, are food for probiotics, promoting their growth and activity. Together, they help maintain a healthy skin microbiome and balanced skin.
How to integrate probiotics into your skincare routine?
- Through diet : Eating fermented foods like yogurt, kefir, sauerkraut, or kombucha can help balance your gut microbiome, which also impacts skin health.
- With specific supplements : There are advanced formulas that combine probiotics and prebiotics designed to strengthen the skin barrier from within.
- With topical products : Some creams and serums include prebiotics and probiotics to strengthen the skin flora and restore damaged skin.
What is the best solution to balance your skin barrier?
Within the field of advanced nutricosmetics, formulas specifically designed to improve skin health from within stand out. One example is SKIN BARRIER FORMULA, which combines probiotics, prebiotics, and zinc to strengthen the skin barrier, reduce inflammation, and improve hydration. Its formula includes active ingredients such as Synbalance® , with antimicrobial and anti-acne action, Actilight® , which supports the skin microbiome, and Optizinc® ZML , in addition to hyaluronic acid, vitamin C, and biotin, which contribute to hydration, antioxidant protection, and cell regeneration.
Taking care of the skin barrier is essential for maintaining healthy, strong, and balanced skin. Incorporating good habits, such as using gentle products, sun protection, and supporting your skin with probiotic ingredients, can make a difference in the long-term health of our skin.
