“Dermatologically tested” – what does that even mean?

The words “dermatologically tested” can be found on all kinds of cosmetic products. It suggests to the consumer that the ingredients of creams, make-ups & co. have been professionally tested. But is this really the case? Tikbow asked an expert.

"Dermatologically tested" – this indication on cosmetics sounds confidence-inspiring. After all, if something has been tested and checked, surely the effect is proven? This is not necessarily so, because it is actually only a kind of advertising slogan, says the Münchner Dermatologe Dr. med. Christoph Liebich.

Dermatologically tested" – not even that informative

The reference means only that a company is assigned to test the product at test persons. "Mostly they make again an application observation with a dermatologist. This includes, for example, an allergy test in which the product is left on the skin for three days," says Liebich. What exactly the test looked like, what came out of it, and how many test subjects took part? The buyer does not find out.

What about other packaging information?

The situation is similar with packaging information such as “clinically tested” or “tested for harmful substances. Because: "Basically, every product that comes onto the market in Europe must be dermatologically tested." Only ingredients that have been tested may be used. Thus, the reference is actually überflüssig and less meaningful than one might assume as a layman.

In any case, the dermatologist said recently in conversation with Tikbow that one need not worry about the products that are available in German drugstores, regardless of whether they are dermatologically tested or not. "There is a very strict cosmetics regulation in Germany, which is also adhered to. As long as the substances are approved, there is no need to worry." Nevertheless, if you want to find out what is in your favorite cosmetics and care products, you can get information from Stiftung Warentest" or "Ökotest" for example.
