We value the quality of our products very highly and therefore relevant products are dermatologically tested by an independent research institute.
Dermatologically tested products achieve this certification by having undergone a series of tests, which ensures that the products do not cause skin irritations or other reactions. The test takes place on humans, and is therefore not "just" a technical test.
With a dermatologically tested skin care product, you are sure to choose a product that your skin can tolerate.
