Abstract

The present invention is concerned with a skin treatment device, comprising a shaver handle housing, a detachable brush head pivotably supported by the shaver handle housing about at least one brush head pivot axis (I) and a gearing mechanism. The shaver handle housing comprises a drive unit for driving at least one drive pin in a rotatory oscillating manner with a first amplitude about an oscillation axis (II) which is at least substantially perpendicular to the at least one brush head pivot axis (I). The brush head comprises a brush rotatable about a brush axis (III) which is at least substantially perpendicular to the at least one brush head pivot axis (I). The brush comprises at least one driven element coupled to the at least one drive pin by means of the gearing mechanism, wherein the gearing mechanism translates the rotatory oscillating movement of the drive pin into a rotatory oscillating movement of the driven element with a second amplitude which is smaller than the first amplitude of the drive pin.
