Cosmetic product tests are conducted to ensure that the products are safe and effective before they are made available to the public. This includes tests to detect the presence of toxic and allergenic substances, as well as to ensure product stability and quality.

Cosmetic product tests can involve in vitro methods and also studies on human volunteers are employed. In vitro tests evaluate the reactivity of the skin to certain substances, while studies on human volunteers assess the skin’s tolerance to the products.

There are 3 mandatory tests which are required for EU and UK registration of the products. They are microbiological test, challenge test and stability-compatibility tests.

Moreover, depending on the type of the product and the claims that are present in the labelling, additional tests could be needed. The most common case is the sunscreen products which require SPF tests or the products which claim “dermatologically tested”, in this case there are some tests that can be valid after our regulatory team checks the reports and validate them under current regulations.

Cosmeservice can offer the assistance to perform these test in a simple, cheap and fast way. You can contact us if you need more information. Also, you can send us your tests if they are already performed and we can check them to let you know if that tests are correct to register the products in the EU and UK markets.

The time required for cosmetic product tests varies depending on the type of test and the complexity of the product, but it can take weeks or even months.
