The Science Behind Holiko

For many years, we have been researching the close connection between skin health and the skin microbiome. We are particularly interested in why sensitive skin becomes unbalanced—and what role the overgrowth of Staphylococcus aureus plays in the development of eczema.

Throughout this journey, one active ingredient has consistently impressed us: colostrum.

It is rich in natural enzymes, immune-active molecules, and growth factors that soothe and protect the skin while supporting its regeneration.

Holiko combines these insights into a skincare regimen that is scientifically grounded and, at the same time, noticeably beneficial.

We are constantly on the lookout for effective skincare ingredients that support a balanced microbiome and visibly soothe the skin.

The connection between skin and gut health

Our search for effective skincare ingredients doesn’t stop at the skin’s surface. The connection between the skin and the gut is undeniable—both are complex ecosystems teeming with microorganisms that play a crucial role in health and well-being.

By understanding how these microbiomes communicate with one another, we can develop skincare products that not only nourish the skin but also help maintain the body’s natural balance.

The Gut Microbiome and Skin Health

The gut microbiome, with its approximately 10 trillion microorganisms, plays a central role in our health. It not only influences the immune system and brain function, but also has a direct impact on the appearance of our skin and hair.

Hormones, neurotransmitters, and vitamins produced by the gut flora have a direct impact on the skin.

For truly effective skincare, it’s not enough to focus solely on external treatments—the gut also needs to be supported and nourished. A holistic skincare routine addresses both aspects, promoting skin that is healthier, more balanced, and visibly more radiant.

What is the skin microbiome?

Just like in the gut, our skin is home to a diverse ecosystem of microorganisms—the skin microbiome. These microorganisms are essential for healthy skin because they:

• protect against harmful germs
• strengthen the skin barrier
• maintain the pH balance of the skin’s protective acid mantle

However, modern skincare habits can disrupt this delicate system.

Frequent showering, strongly scented soaps, or harsh cleansing products remove not only dirt but also beneficial microorganisms. The skin’s protective acid mantle loses its stability, the skin barrier weakens—and the skin becomes irritated more easily.

Although the skin’s microbiome can regenerate itself to some extent, a holistic skincare routine should specifically support both the skin and its microbiome to maintain long-term health.

Why microbiome-friendly skincare is important

Microbiome-friendly skincare products strengthen the skin's natural flora, support the skin's natural defenses, and can help alleviate symptoms such as irritation, dryness, or a tendency toward eczema.

Studies show that people with eczema often:

• have higher levels of Staphylococcus aureus on their skin
• have a lower diversity of protective bacteria

Both of these factors weaken the skin's natural resilience.

Microbiome-friendly skincare can help:

• Reduce itching and redness
• Alleviate eczema symptoms
• Restore the skin's balance

The Benefits of Colostrum in Skincare

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

What makes colostrum so special?

1. Immune-boosting properties.
Colostrum contains natural antibodies and immune factors that fight germs, stabilize the microbiome, and support wound healing by regulating inflammation and bacterial growth.

2. Regenerative growth factors.
These promote cell regeneration, improve elasticity, and support the visible regeneration of the skin.

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

4. Nutrient-rich formula.
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 factors, and essential fatty acids, colostrum visibly contributes to skin rejuvenation: fewer wrinkles, greater elasticity, improved resilience, and a fresh complexion.

Why Gut and Skin Health Are Connected

The gut microbiome plays a key role in overall health—and therefore also in skin health. Hormones, vitamins, and signaling molecules produced in the gut have a direct effect on the skin and hair.

A balanced gut microbiome can:

• Reduce inflammation
• Strengthen the skin barrier
• Reduce sensitivity
• Promote regeneration

That’s why microbiome-friendly skincare and colostrum-based products complement each other perfectly.

They support the body from the outside and the inside—for skin that looks stronger, more balanced, and visibly younger.
