Courage + Khazaka electronic GmbH

The Company

air backair frontFounded in 1986, by Mr. Wilfried Courage and Prof. hc. Gabriel Khazaka, Courage + Khazaka electronic GmbH introduced the first scientific measurement tools to objectively quantify parameters on the skin. Until today we have always been the world market leader in this field. Nobody else offers such a complete range of measurement parameters. Even after 30 years, we are constantly developping new parameters for skin & hair.

In general C+K offers two ranges of products, the scientific skin testing systems and the instruments to determine the skin type  by measurements to recommend treatment and products.

Use in the scientific field:

The devices have become the worldwide standard

  • in the R&D departments of cosmetic/pharmaceutical/raw material companies
  • in independent testing laboratories undertaking efficacy testing and claim support.
  • Due to their user friendliness and reasonable prices the instruments are not only used by large international companies but also by smaller and medium sized cosmetic companies to test their products at each stage of the development.
  • In dermatological fundamental research
  • occupational health has found that besides the tests of other body organs and functions (e.g. lung, ears, eyes, etc.) measuring the skin is a useful way of predicting where the skin is at risk and thus preventing skin disease among workers and has also an educational effect (to show the necessity of using skin care and protection products).

Of course this is only a selection of the user groups. There are many others interested in the skin (e.g.  food industry, textile industry) etc. Even in space skin physiological tests were done with the C+K devices on an ISS mission.


Hundreds of scientific studies performed with the C+K equipment are available.
