We claim the ornamental design for a personal care device, as shown and described.
FIG. 1 is a front, right, top perspective view of the personal care device, but with selected portions being illustrated in broken lines and thus not forming a part of the claimed design;
FIG. 2 is a front elevational view of the personal care device of FIG. 1;
FIG. 3 is a right side elevational view of the personal care device of FIG. 1, the left side elevational view being a mirror image thereof;
FIG. 4 is a back elevational view of the personal care device of FIG. 1;
FIG. 5 is a top end view of the personal care device of FIG. 1; and,
FIG. 6 is a bottom end view of the personal care device of FIG. 1.
The broken line showing of portions of the personal care device is included for the purpose of illustrating environmental structure and forms no part of the claimed design.
