The invention claimed is: 1. A metering device for a product intended to be applied to skin, in particular a pharmaceutical or cosmetic composition, comprising: an applicator stick that includes a longitudinal groove divided into a series of compartments and graduations provided perpendicular to the groove, that extend from a top surface of the applicator stick in a depth direction of the groove, wherein said groove accommodates a quantity of composition corresponding to a defined surface area of skin to be treated, wherein said quantity of composition is defined by the series of compartments, and wherein the groove defines an uncovered depression in the top surface of the applicator stick such that an entirety of the groove is exposed opposite the depression; wherein: one end of the groove corresponds to a start of a first compartment; the graduations divide the groove into the series of compartments; the graduations define the quantity of composition in each of the series of compartments of the groove; a volume of each of the compartments is defined by a length of the compartment in the axial direction; the applicator stick includes a flared circular portion and a narrow portion; the narrow portion extends from a first end of the applicator stick to the flared circular portion in an axial direction of the groove; the circular portion extends beyond the groove in an axial direction of the groove to a second end of the applicator stick; the circular portion includes a greater width than the narrow portion in a transverse direction of the applicator stick; the circular portion is dimensioned and configured so as to facilitate handling the applicator stick; and the composition is calcitriol ointment. 2. The metering device according claim 1, wherein the groove includes a first compartment, a second compartment, a third compartment, and a fourth compartment. 3. The metering device according to claim 1, wherein the first compartment is able to contain a quantity of composition corresponding to an area of 0.8 to 1.2% of a total surface of a body. 4. The metering device according to claim 2, wherein the first compartment and the second compartment are able to contain a combined quantity of composition corresponding to an area of 2.4 to 3.6% of a total surface of a body. 5. The metering device according to claim 2, wherein the first compartment, the second compartment, and the third compartment are able to contain a combined quantity of composition corresponding to an area of 4.8 to 7.1% of a total surface of a body. 6. The metering device according to claim 2, wherein the first compartment, the second compartment, the third compartment, and the fourth compartment are able to contain a combined quantity of composition corresponding to an area of 7.2 to 10.8% of a total surface of a body. 7. Device according to claim 2, wherein the first compartment is able to contain a quantity of 0.35 g to 0.54 g of calcitriol ointment. 8. The metering device according to claim 2, wherein the first compartment and the second compartment are able to contain a combined quantity of 1.08 g to 1.62 g of calcitriol ointment. 9. The metering device according to claim 2, wherein the first compartment, the second compartment, and the third compartment are able to contain a combined quantity of 2.16 g to 3.20 g of calcitriol ointment. 10. The metering device according to claim 2, wherein the first compartment, the second compartment, the third compartment, and the fourth compartment are able to contain a combined quantity of 3.24 g to 4.86 g of calcitriol ointment. 11. The metering device for metering a drug intending to be applied to the skin according to claim 1, wherein the groove has a uniform cross sectional area in an axial direction of the groove. 12. The metering device for metering a drug intending to be applied to the skin according to claim 1, wherein the groove has a constant depth and a constant width perpendicular to the axial direction of the groove. 13. The metering device for metering a drug intending to be applied to the skin according to claim 1, wherein each compartment in the series of compartments has a successively larger volume. 14. The metering device for metering a drug intending to be applied to the skin according to claim 1, wherein the applicator stick includes a lower surface on an opposite side of the applicator stick with respect to the top surface, and wherein the groove defines a bulge on the lower surface of the applicator stick such that the metering device is inclined when placed on a flat surface.
