FAQ

Who are our products suitable for?

Our concept is simple:

minimalist – no fillers, no unnecessary ingredients
effective – every ingredient enhances the product’s performance
natural – exclusively ingredients of natural origin

Holiko stands for skincare stripped down to what truly matters — and that is exactly why it works so effectively.

What is the skin microbiome?

The skin microbiome is the community of bacteria, viruses, and fungi that live on our skin. It is as unique as a fingerprint and varies depending on the area of the body and age.

Healthy skin has a diverse microbiome in which “good” bacteria regulate the growth of “bad” bacteria, helping to maintain a balanced skin environment.

What is the brain–gut–skin axis?

The brain–gut–skin axis describes the connection between the brain, the gut, and the skin. Scientific studies show that a healthy gut microbiome can reduce stress-related skin inflammation.

This means that the body and the skin communicate much more closely than one might expect.

What does resilience mean in relation to the skin?

Resilience refers to the skin's ability to remain healthy or recover more quickly after experiencing stress. The term originally comes from psychology—but the skin also needs resilience to better withstand irritation, environmental stress, and external strain.
