Safety testing of cosmetic products: Overview of established methods and new models
Cosmetic products need to have a proven efficacy combined with a comprehensive toxicological assessment. An increasing number of alternatives to animal testing has been developed and validated for safety and efficacy testing of cosmetic products and cosmetic ingredients. For example, 2D cell culture models derived from human skin can be used to evaluate anti-inflammatory properties, or to predict skin sensitization potential; 3D human skin equivalent models are used to evaluate skin irritation potential; excised human skin is used as the gold standard model for the evaluation of dermal absorption. The aim of this webinar is to give an overview of the main in vitro and ex vivo alternative models and methods used in the safety testing of cosmetic products: skin sensitization potential, genotoxicity potential, skin and eye irritation, endocrine properties, and dermal absorption, with a focus on dermal absorption testing.
