Cosmetics: testing and evaluation

We manage cosmetics with added health benefits – commonly known as borderline cosmetics – throughout their life cycle.

Marketability and quality

Borderline cosmetics, such as products for treating scars, are subject to particularly strict regulatory requirements. We support manufacturers and distributors in meeting these requirements. This includes checking whether a product is marketable as a cosmetic – or whether it is a medicinal product, medical device or other type of product. A product’s formulation, labelling, claims and presentation can all influence which legal category it falls under.

We also support manufacturers and distributors when it comes to quality and safety. We organise dermatological and clinical testing. We test manufacturing quality by performing cosmetics GMP audits in accordance with ISO 22716, plus we respond to consumers’ questions and complaints from official bodies regarding quality and safety.


The EU Cosmetics Regulation 1223/2009 calls for the safety of cosmetic products to be monitored for full awareness of adverse reactions and effects on human health. Constant cosmetovigilance is required from the moment of market launch. Adverse reactions are to be recorded in a product’s safety report, and serious adverse reactions must be reported to the proper authorities.

Diapharm helps with safety assessments and provides cosmetovigilance services on behalf of a number of companies.
