Since 1900 and for four generations here in Salon de Provence, the Fabre family has kept TRADITIONAL CRAFT SKILLS alive making Marseille soap and black soap with olive oil. OUR TRADE SECRET is a warrant of a natural soap that is healthy for people and for the environment. Marie and Julie Bousquet-Fabre are proud to follow on in the footsteps of their great-grandfater, MARIUS FABRE whose adventure began in 1900.
