How will we test products in stores in safe, hygienic ways? How can samples be distributed to ensure consumer comfort? What innovative, creative solutions can be found? These very questions were at the heart of the fourth edition of the competition "Think Tank: how will we perfume ourselves tomorrow?” sponsored by COTY and organized by Easyfairs Oriex, the group behind the PCD trade fair in Paris dedicated to the worldwide perfume and cosmetics packaging community. On the occasion of this competition, students from L’École Supérieure Européenne de Packaging (ESEPAC) and l’École Supérieure du Parfum (ESP) worked together to find real solutions to the current dilemma facing the cosmetics and fragrance industry now: how to test fragrance and other products in-store while respecting hygienic and environmental restrictions.
