Heyfair GmbH

Product info:

Heyfair develops a new generation of hygiene products that use visual cues to indicate whether they are being used correctly.

Hand washing is proven to be one of the most effective hygiene measures. However, only one in ten hand washings is done properly.

That’s why we developed VisiSoap. VisiSoap shows us clearly and colorfully what we often overlook: both when soaping up and when rinsing off. VisiSoap makes washing our hands simply more effective – we wash more consciously and it’s a lot more fun!

When it comes to ingredients, we place special attention on natural origin and skin compatibility. Since health protection naturally also includes the protection of the skin.

Dermatest test procedure:

Epicutaneous testing (Patch testing) under dermatological control. The test product was applied once occlusively for 24 hours on 30 subjects . Skin assessments have been performed before and 24, 48 and 72 hours after application. No subject showed any irritative skin reactions during this study. Thus, it can be concluded that the product does not have high irritation potential and the product will not cause adverse skin reactions when properly used.

The Dermatest seal:

When it comes to your hands, it is all the more important for you to know which products are dermatologically tested and safe. Certificates like those from us as an independent institute help you to assess the safety of products. VisiSoap met our basic test requirements and therefore received our Dermatest Guarantee Seal.
