The link between your gut and healthy skin?
When people want to improve their skin, they usually think of skincare.
But what if healthy skin doesn't just start in the bathroom, but also in your gut?
Within the Sarasin 360™ Skin Longevity Method, we look beyond just the skin. More and more research shows a strong connection between the gut microbiome and skin health. This connection is known as the gut-skin axis.
In other words: what happens in your gut can become visible on your skin.
What is the gut microbiome?
Your gut microbiome consists of billions of bacteria, fungi, and other microorganisms that live together in your digestive system. A healthy microbiome helps with food digestion, supports the immune system, and plays an important role in inflammatory processes.
When the balance between good and less beneficial bacteria is disrupted, it can have consequences for various systems in the body — including the skin.
Why is a healthy gut important for the skin?
The intestinal wall forms an important protective barrier.
In a healthy situation, this barrier ensures that nutrients are absorbed and unwanted substances are eliminated. When this protective function diminishes, substances that normally remain in the intestine can more easily enter the bloodstream.
This can contribute to chronic low-grade inflammation in the body. And these inflammatory processes play an important role in skin aging, skin sensitivity, and the overall quality of the skin.
Therefore, when it comes to skin health, we not only look at what you apply to the skin, but also at what is happening internally.

The role of inflammation in skin aging
Healthy skin is more than just beautiful skin.
It is strong, resilient, and functions optimally.
Chronic inflammation can disrupt these processes. It is also linked to accelerated aging processes in the body, also known as inflammaging.
Within skin longevity, we therefore focus on supporting the factors that contribute to a healthy internal environment, including the gut microbiome.
Which foods support the gut microbiome?
A healthy gut microbiome needs nourishment to thrive.
Fiber-rich foods play an important role here as they serve as a food source for beneficial gut bacteria.
Examples include:
- Fiber-rich grains
- Blueberries
- Chia seeds
- Bananas
- Other plant-based foods rich in prebiotic fiber
These nutrients not only support the gut microbiome but also contribute to a healthier internal environment.
What does collagen have to do with this?
Within our 360° approach, we look at various factors that support skin quality.
Collagen tripeptides provide building blocks such as glycine, proline, and hydroxyproline. These amino acids play a role in skin structure, elasticity, and supporting the skin from within.
Therefore, collagen support is one of the pillars within our Cellular™ approach.

The conclusion
Healthy skin does not exclusively begin on the surface.
The gut microbiome, inflammatory processes, and nutrition all play a role in how the skin looks and functions.
That's why within skin longevity, we look at the bigger picture.
Because when you support the skin from both within and without, you create the best foundation for healthy, strong, and resilient skin in the long term.
