PURPOSE:To provide a lipstick having sheath-core structure, having soft and light touch, and good spreadability and capable of protecting the lips with uniformly adhered layer, composed of a core and a sheath having different compositions each other. CONSTITUTION:A coaxially integrated sheath-core-type lipstick. The oleaginous base of one of the component is composed of (a) 53-85 wt% of a low-viscosity base having a viscosity of <=80 cp at 36 deg.C (e.g. liquid paraffin, squalane, isopropyl palmitate, etc.) and (b) 15-47 wt% of a base which is solid at 36 deg.C (e.g. beeswax); and that of the other component is composed of (a') 40-90 wt% of viscous oleaginous base having a viscosity of >=200 cp at 36 deg.C and (b') 10-60 wt% of a solid oleaginous base.
