Dermatology Test

Dermatology Test
Dermatological tests are applied to evaluate the effects of cosmetic products on human skin. These tests include laboratory studies and clinical trials to determine whether products cause skin irritation or other adverse reactions.
Dermatological tests are performed as in vivo clinical tests on volunteers. These tests are carried out by experts in the field (for example, dermatologists) in accordance with the Declaration of Helsinki and in line with the "Guideline on the Evaluation of Human Skin Compatibility of Cosmetic Products or Raw Materials" published by the Turkish Medicines and Medical Devices Agency.

Cosmetic product samples are left on the volunteers' covered back areas for 48 hours and are then removed. The first evaluation is made after half an hour and left open for 24 hours under the same conditions. At the end of 72 hours, a second evaluation is made and the results are graded by dermatologists and responsible researchers. Results are interpreted as "Non-irritating / Not a cause of irritation" to "Very irritating / Highly a cause of irritation".
