What are efficacy tests in cosmetics?
Efficacy tests in cosmetics are scientific studies designed to objectively demonstrate that a product fulfills the declared effects on the skin. These studies are essential to support claims related to hydration, skin appearance, comfort, or visible improvement of the skin's condition.
According to the European Commission's Technical Document on Cosmetic Claims, any cosmetic claim must be supported by adequate, verifiable, and consistent evidence with the product's formulation (European Commission, 2013). For this reason, efficacy tests are a key tool in cosmetic development.
How is the efficacy of a cosmetic product evaluated?
The evaluation of cosmetic efficacy is carried out following recognized European methodologies. As stated in Cosmetics Europe's Guidelines for the Evaluation of the Efficacy of Cosmetic Products, studies must be based on clear, reproducible protocols adapted to the benefit to be demonstrated (Cosmetics Europe, 2008).
Typically, these studies include:
-
Product application under real-use conditions
-
Clinical evaluation of the skin before and after the study period
-
Objective analysis of the results obtained
The duration of the study and the type of evaluation are defined based on the effect to be justified.
The role of efficacy tests at FARMA DORSCH
At FARMA DORSCH, efficacy tests are part of the scientific approach applied to the development of each formula. These studies ensure that products deliver results consistent with their claims and comply with European regulatory requirements.
This commitment to objective evaluation and transparency reinforces confidence in the products and guarantees cosmetics based on scientific criteria, not unsupported promises.
Why choose cosmetics with efficacy tests?
Choosing products with efficacy tests means opting for cosmetics that adhere to the principles of rigor, truthfulness, and responsibility required by European regulations on cosmetic claims (European Commission, 2013).
Efficacy studies allow for differentiating products formulated with scientific criteria and offer consumers clear and reliable information about what to expect from a cosmetic.
