Our blog is a space for understanding how sunlight and UV radiation interact with the human body. We explore different aspects of light, from its role in everyday functioning to the risks associated with excessive exposure. We show how to approach light more consciously, taking into account both its significance and its limitations.
Explore with us how light fits into everyday life, discover different aspects of tanning, both in the sun and in tanning beds, and dive into scientific research that helps better understand sunlight, UV radiation, and the technologies related to it.

Human skin colour is not just a matter of aesthetics – it is a record of thousands of years of evolution, in which sunlight and nutrients such as folate shaped our health and survival.
Pigmentation genes are now one of the fastest-growing areas of research. Just three decades ago, our knowledge of skin colour was very limited – it was believed that only a few single genes were responsible for it.
Skin color is the result of a brilliant survival strategy – for thousands of years, pigmentation adapted to the amount of sunlight in the environment.
Today, however, our lives look very different from the past – we spend most
Skin colour is the result of a brilliant survival strategy, encoded in our bodies over thousands of years. Skin pigmentation is no accident – it is nature’s precise response to the amount of light in our environment.
Cardiovascular diseases are responsible for as much as 32% of all deaths worldwide, making them the leading cause of mortality globally. For years, UVA radiation has had a bad reputation. And yet, it is precisely this type of light that
