What tests have been carried out on the stem cells in HANZZ+HEIDII products?

The effect of the active ingredients was tested on cell cultures with human epidermal stem cells. These tests prove that the active substances can maintain the stem cells' ability to divide for longer, even when the cells were additionally stressed with UV light.

Tests on the 3D epidermis model show that even aged skin stem cells can still build up a complete epidermis through the application. This means that aged stem cells treated with edelweiss and snow algae have an activity like young stem cells. These positive effects could also be confirmed in tests with test persons.
