Description of the test:
Measurement at T=0 before the application and after a preset duration agreed upon with the sponsor;
Temperature control using an infrared non-invasive thermometer;
Evaluation of the erythemal response through skin colorimetry using a Mexameter® MX18 colorimeter (Courage-Khazaka GmbH – Germany);
Evaluation by clinical experts of the general conditions of the skin and epidermal tolerability during use;
Subjective evaluation through predefined questionnaire with numerical score system (visual analogical scale) and judgement of the tolerability and heat/chill feeling as perceived during the application of the product;
Comparative photography with colorimetric reference captured with a 100 mm macro objective and normalization of the color with coaxial circular flash.
In vitro test for the evaluation of the protective effect against air pollution. The purpose of this test is to evaluate the efficacy of the sample in reducing ROS release in response to a mix of heavy metals and atmospheric dust particulate in a skin-derived cell model.
