Vichy 7 Days Treatment is an intensive anti-perspirant cream designed to regulate excessive sweating. This 30ml treatment provides week-long effectiveness through a concentrated formula that helps control perspiration while being gentle on sensitive skin. This dermatological treatment comes in cream form and is meant to be applied at night for optimal results. The product is formulated with Vichy's signature mineralizing thermal water and is free from harsh ingredients that could irritate sensitive underarm skin. It's recommended as a weekly intensive treatment rather than a daily deodorant.
