A personal care device, preferably an electric toothbrush, comprising a personal care head, preferably a toothbrush head; a force sensor structured and/or arranged for acquiring force sensor data indicative of a force value with which the personal care head is pushed against a treatment surface along at least a first force direction; a processor structured and/or arranged for determining the force value from the force sensor data; a drive unit structured and/or arranged for driving the personal care head into a motion that is characterized by at least one motion parameter being one from the list comprising a speed, an amplitude and a frequency, the motion preferably being an oscillatory rotational motion; and a control unit structured and/or arranged for controlling the motion parameter of the personal care head in dependence on the determined force value such that in a first force value range (110; 130, 131) extending from a first lower force value to a first upper force value the motion parameter is gradually increased from a first motion parameter start value to a first motion parameter end value when the force value increases from the first lower force value to the first upper force value and for controlling the motion parameter such that in a second force value range (111; 132) extending from a second lower force value to a second upper force value and being subsequent to and optionally adjoining the first force value range (110; 130, 131) the motion parameter is gradually decreased from a second motion parameter start value that is identical with the first motion parameter end value to a second motion parameter end value when the force value increases from a second lower force value being identical to the first upper force value to a second upper force value so that the first motion parameter end value represents an overall peak value of the motion parameter. a personal care head, preferably a toothbrush head; a force sensor structured and/or arranged for acquiring force sensor data indicative of a force value with which the personal care head is pushed against a treatment surface along at least a first force direction; a processor structured and/or arranged for determining the force value from the force sensor data; a drive unit structured and/or arranged for driving the personal care head into a motion that is characterized by at least one motion parameter being one from the list comprising a speed, an amplitude and a frequency, the motion preferably being an oscillatory rotational motion; and a control unit structured and/or arranged for controlling the motion parameter of the personal care head in dependence on the determined force value such that in a first force value range (110; 130, 131) extending from a first lower force value to a first upper force value the motion parameter is gradually increased from a first motion parameter start value to a first motion parameter end value when the force value increases from the first lower force value to the first upper force value and for controlling the motion parameter such that in a second force value range (111; 132) extending from a second lower force value to a second upper force value and being subsequent to and optionally adjoining the first force value range (110; 130, 131) the motion parameter is gradually decreased from a second motion parameter start value that is identical with the first motion parameter end value to a second motion parameter end value when the force value increases from a second lower force value being identical to the first upper force value to a second upper force value so that the first motion parameter end value represents an overall peak value of the motion parameter.
