Clinical Testing of Cosmetics and Cosmetic Claims Substantiation

Depending on the manner of brand communication, i.e. the client's requirements, it is possible to conduct various tests in order to substantiate the claims being communicated for that product.

For example, if it is communicated that the product is allergen free and that it is dermatologically tested, then it is necessary to perform an analysis of all the known allergens expected in the product, as well as dermatological tolerance tests. Furthermore, if it is communicated that the product has a sun protection factor, then it is necessary to prove it by appropriate tests. It is also possible to conduct the following tests to prove efficacy: measurement of biochemical parameters such as firmness and elasticity, hydration level, cellulite, intensity of wrinkles, luminosity, level of skin pigmentation before and after use, and customer satisfaction survey.
