Dermatest seal

Dermatest is an independent dermatological institute that tests products that come into contact with the skin.

A team of allergists, dermatologists and biologists carefully tests these products for tolerability and effectiveness , ensuring they are safe for consumers.

After testing, the institute awards the Dermatest seal, which confirms that the product is skin-friendly and safe.

How does such a test work?

The institute carries out a patch test.

  • The test product is applied in suitable concentrations to the skin of test subjects, usually on the back or upper arms.
  • After 24, 48 and 72 hours, the skin is examined for redness or other abnormalities.
  • If nothing of the sort can be found, the product has passed the test.

We are very proud that our washing strips have been awarded the Dermatest seal of "very good".
