Abstract: A marking module for an appliance intended for applying a colorant for permanent makeup or tattooing has a channel and at least one needle that is able to move longitudinally in said channel between a retracted position in which a distal end of the needle is located inside said channel and an extended position in which the distal end of the needle protrudes from said channel. The marking module has a reservoir of colorant and said reservoir communicates with said channel only in a region situated downstream of the needle when this needle is located in said retracted position. An appliance for applying a colorant for permanent makeup or tattooing has a marking module as defined above and a module for actuating the needle of the marking module.
