Abstract: A personal care device is provided with a cutting unit comprising an external cutting member and an internal cutting member. A virtual skin plane is located on a side of the external cutting member facing away from the internal cutting member. The internal cutting member comprises cutting elements each having a first cutting edge. The external cutting member comprises hair-entry apertures each having a second cutting edge. In a starting position of cutting a hair situated in a cutting position in the hair-entry aperture and extending perpendicularly to the virtual skin plane, the first cutting edge is in contact with the hair in a first contact position, and the second cutting edge is in contact with the hair in a second contact position, wherein the first contact position is closer to the virtual skin plane than the second contact position.
