Blue wax is based on the original formula. Ideal for use on face as well as body on normal skins. Liposoluble wax semisolids at room temperature but easily melts in the heater-applier. Its composition (rosin derivatives) gives it a texture that adheres to the hair but does not dry. Its advantages are its low temperature (ideal for heat-sensitive skin), hygiene (single use) and comfortable, easy application (thanks to a built-in roll-on applicator).
