Science Behind Holiko

For many years, we have been exploring the close connection between skin health and the skin microbiome. We are particularly fascinated by why sensitive skin falls out of balance — and how the overgrowth of Staphylococcus aureus contributes to the development of eczema.

Along this journey, one active ingredient has consistently stood out: colostrum.

It is naturally rich in enzymes, immune-active molecules, and growth factors that help soothe, protect, and support the skin’s regeneration.

Holiko brings these insights together to create care that is scientifically grounded and genuinely feels good on the skin.

We are continuously searching for effective active ingredients that help support a balanced microbiome and visibly soothe the skin.

Connection Between Skin and Gut Health

Our quest for effective skincare ingredients doesn’t end at the skin’s surface. The connection between the skin and the gut is unmistakable — both are complex ecosystems filled with microorganisms that profoundly influence health and wellbeing.

By understanding how these microbiomes communicate with each other, we can develop skincare that not only nourishes the skin, but also supports the body in maintaining its natural balance.

Darmmikrobiom und Hautgesundheit

The gut microbiome — home to around 10 trillion microorganisms — plays a central role in our overall health. It influences the immune system, brain function, and directly affects the appearance of skin and hair. Hormones, messengers and vitamins produced by the gut flora have a direct impact on the skin.

Truly effective skincare therefore goes beyond topical treatment — the gut must also be supported and nourished. A holistic care routine considers both sides, promoting skin that is healthier, more balanced, and visibly more radiant.

Die Vorteile von Kolostrum in der Hautpflege

Colostrum — the first milk produced by mammals after birth — is an exceptional natural ingredient for skin health and regeneration. Bovine colostrum, in particular, contains a unique combination of immune-active molecules, growth factors, nutrients and soothing components.

What makes colostrum so special?

1. Immune-active properties.
Colostrum contains natural antibodies and immune factors that help fight harmful microbes, stabilize the microbiome and support wound healing by regulating inflammation and bacterial overgrowth.

2. Regenerative growth factors
These stimulate cell renewal, improve elasticity and support visible skin regeneration.

3. Anti-inflammatory effects.
Omega-3 fatty acids such as DHA help calm irritation and bring stressed or sensitive skin back into balance.

4. Nutrient-rich composition.
Vitamins (A, B, C, E), minerals (zinc, copper, selenium) and antioxidants protect the skin from free radicals and promote a radiant, healthy complexion.

Colostrum as an anti-aging ingredient

Thanks to its combination of antioxidants, regenerative compounds and essential fatty acids, colostrum visibly contributes to skin rejuvenation: fewer lines, improved elasticity, greater resilience and a refreshed, healthy appearance.

Warum Darm- und Hautgesundheit verbunden sind

The gut microbiome plays a key role in overall health — and therefore in the condition of the skin. Hormones, vitamins and messengers produced in the gut have a direct influence on skin and hair.

A balanced gut microbiome can

• reduce inflammation
• strengthen the skin barrier
• decrease sensitivity
• support regeneration

This is why microbiome-friendly skincare and colostrum-based products complement each other so well.

Together, they support the body from the inside and the outside — for skin that feels stronger, more balanced and visibly more youthful.
