• Why use extracts from plant stem cells and not typical plant extracts as in usual practice?

The alpine rose plant is a popular, well known plant, which is registered in the Swiss database of medicinal plants. Alpine roses are typical Swiss flowers that grow in the mountains. Due to the popularity and climate changes the alpine rose has a high risk of extinction. Therefore alpine rose is protected by Swiss government.

Stem cell technology gives a unique possibility to get a large amount of cells (callus) from a very small amount of plant material, thus protecting the beautiful alpine rose’s growth in natural environment.

  • It sound controversal to use plant stem cells in the anti aging creams. Is it legal to use stem cell?

The definition plant “stem cell” may be misleading. It would be better to call it as extracts from the plant cells.
Stem cell technology used in medicine differs from the stem cell technology used in cosmetics.

In cosmetics there are not used human cells, but plant cells.

The definition of stem cells in plants are not the same as of stem cells in the human body. Plant cells are taken from parts of the plant. Production of the plant stem cells is not hi-tech.

Moreover, in cosmetics not real cells are used, but extracts from the stem cells. Extraction is made under homogenization with high pressure. Thus there are no live stem cells, but dead cells in cosmetical products.

Therefore stem cells in skincare cosmetic products are like products containing plant extracts.

  • How are plant stem cells from Alpine rose created?

To get the plant stem, Alpine rose leaves are pricked. Number of cells start to grow in order to heal the wound. This wound healing tissue, called callus, is harvested and cultivated in very low temperature in order to acclimatize the cells. Afterwards extraction is made under homogenization with high pressure. Thus there are not live stem cells but dead cells, since the cell walls are mechanically disrupted to release their contents during the extraction process.

  • Recently many companies have started to introduce anti-aging products with stem cells extracts. Why should I prefer yours?

Firstly, the amount of stem cells in the product is important. Usually recommended use level is around 0,4-1%. Therefore, check the ingredient list on the label to find out the amount. Vivasan guarantee the high quantity of the extracts.
Secondly, Vivasan guarantee the high quality of the extracts, created during the totally controlled processes.
Quality of Vivasan products is confirmed by the independent Swiss therapeutic agency Swiss Medic.

  • Describing alpine stem cells in cosmetics you mention self-renewable term. What do you mean by self-renewable? What is the role of the alpine stem cells?

The term self-renewable it means the continuous process of replacements of the dead skin cells in the upper skin layer (epidermis), which depends on the activity of the skin stem cells. The rate of renewal is declines with the ages. The upper skin layer replace itself in some 20 days in young people, in 30 days in middle-aged people, the rate of renewal declined even more after 50 age. Researchers indicate that extracts from the Alpine rose stem cells may enhance their function, thus improving the natural process of skin self-renewal.
