Who are we ?
To evaluate their cosmetic products, brands call on independent companies such as the IEC. With more than 27 years of experience and 5,000 products tested each year, the IEC is positioned as the world leader in cosmetic clinical study testing.
Located in the heart of Lyon, near the Tête d'Or park, its premises offer you easy access and equipped facilities so that you can participate in studies in the best conditions.
