Seal of approval

We want our clients to be successful. For this reason we have devised a system that enables our clients to enlighten their customers – the consumers, in other words – about the quality of their products that we have tested and approved.


The ‘Original DERMATEST®’ seal is a guarantee for the reproducibility of test methods and also provides reassurance for consumers and manufacturers. Products awarded this seal live up to the promise of the tested and confirmed quality. To clarify the significance of the seal there are three tiers.
Where more intricate testing methods are involved, the seal is accompanied by a big promise: the three-star guarantee. It is not only impressive but verifiable, too.
The five-star guarantee stands for the most sophisticated application tests, whose conclusiveness has been established with the greatest precision. The seal is also emblazoned with the impressive statement ‘Clinically tested’.
