Abstract
A lipstick (13, 17, 19, 21, 23) with external lateral surface having a tridimensional design is obtained by a process comprising laser-working the external lateral surface of a head part (2), previously mirror-polished, of a rough tap (1). The process may include the final pearling of the lipstick (13, 17, 19, 21, 23) by means of a cyclone system (14) to obtain a pearled lipstick (16, 18, 20, 22, 24).
