“CHacoll originates from medical research and has only recently undergone further studies in order to gather information about its mechanism of action. The influence of CHacoll on the formation and cross-linking of collagen, the skin barrier and fat degradation was investigated in elaborate experiments. These study results help to explain the mechanism of action and the very encouraging results of the application studies. CHacoll interacts with keratinocytes. These then secrete special factors which, when in contact with fibroblasts, bring about the stimulation of collagen synthesis, and when in contact with fat cells, cause the breakdown of fat.” – Prof. Dr. Sven Gohla, Zurich University

With the new, further developed Firm Skin Upper Arms, skin689 has an emulsion that tightens the skin of your upper arms. Using CHacoll as part of a unique combination of active ingredients, the emulsion specifically supports the formation of the collagen fiber network by stimulating 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 lifted – the so-called bingo wings are cosmetically tightened*.

exclusive ingredients
“The skin689 compound stimulates so-called lipolysis in adult fat cells on the gene expression pattern. Put simply, CHacoll can stimulate fat cells in the skin to metabolize fats to a greater extent, and furthermore 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 tighter skin

DermCom strengthens connective tissue – it is the world’s first active ingredient with in-vivo evidence for collagen and elastin regeneration

The patented active complex CoAXEL stimulates the energy metabolism, promotes the breakdown and removal of fatty acids and drains the tissue.

das sagen unsere Experten
“Support for the first signs of skin sagging on the upper arms. Summer can be short-sleeved!”

“Our patients were very pleased with initial results after only three to four weeks. The skin becomes firmer, the skin texture is improved.”

“Stimulates fat cells in the skin to metabolize more fats, as well as collagen biosynthesis. This structural depth effect is perfect for tightening the upper arms.”
