“CHacoll comes from medical research and has only recently been subjected to further studies to gain information on the mechanism of action. Extensive experiments were carried out to investigate the influence of CHacoll on the formation and cross-linking of collagen, the skin barrier and fat breakdown. These study results help to explain the mechanism of action and the very strong results of the application studies. CHacoll occurs in interaction with the keratinocytes. These then produce special factors that stimulate collagen synthesis when they come into contact with fibroblasts, and break down fat when they come into contact with fat cells.” – Prof. Dr. Sven Gohla, University of Zurich

With the new, further developed Firm Skin Upper Arms, skin689 has an emulsion that tightens the skin of your upper arms. With the help of CHacoll as part of a unique combination of active ingredients, the emulsion specifically supports the formation of the collagen fiber network by stimulating the energy metabolism and promoting the breakdown of fatty acids. The connective tissue is strengthened so that the skin looks fresh and vital again. At the same time, the skin “waves” less when the upper arms are raised – the so-called waving arms (bingo wings) are cosmetically tightened*.
Gently massage in once a day.

exclusive active ingredients
“The skin689 active ingredient stimulates the so-called lipolysis on the gene expression pattern in adult fat cells. To put it simply: CHacoll can stimulate the fat cells in the skin to metabolize fats more intensively, and also stimulate collagen biosynthesis”. - Prof. Dr. Sven Gohla

The proprietary patented active ingredient CHacoll from medical research promotes the formation of collagen fibers and reduces fat cells - for firmer and firmer skin
