Products tested with the highest quality and safety standards that a patch test can offer.

The already exacting requirements for our standard patch testing have been extended to include positive and negative controls, ensuring that you can have the greatest possible confidence in the results. To test product compatibility under stringent conditions, all substances are applied for 24 hours under closed conditions. For a positive response to be triggered, the irritation/sensitivity threshold must be exceeded. Approval is also obtained from an ethics committee.
