         4 . A skin treatment device according to  claim 1 , wherein the first attachment is coupled to the drive unit via an eccentric wheel. 
     
     
         5 . A skin treatment device according to  claim 1 , wherein the drive unit comprises an output element and a rotary support element, the rotary support element comprising protrusions, and further, wherein the first attachment comprises a skin treatment element and a chassis for the skin treatment element, the chassis comprising a multitude of recesses to cooperate with the protrusions of the rotary support element of the drive unit, wherein the chassis can be supported by the rotary support element and, wherein the protrusions can be brought into an engagement position with the recesses and, while the chassis is supported by the rotary support element, into a disengagement position with the recesses. 
     
     
         6 . A skin treatment device according to  claim 5 , wherein the recesses form a toothed ring. 
     
     
         7 . A skin treatment device according to  claim 5 , wherein the protrusions are provided in the form of latches. 
     
     
         8 . A skin treatment device according to  claim 1 , comprising a first attachment which comprises a drive shaft for the transmission of a rotary movement from the drive unit to the drive axis, the drive shaft being linked to a sprocket, the sprocket engaging with a crown gear wheel and crown gear wheel being linked to the drive axis. 
     
     
         9 . A method for treating human skin, the method comprising the following steps:
 a. treating the skin with an oscillating brush using a skin treatment device comprising a drive unit and a first attachment, the first attachment comprising the brush; and   b. removing body hair from the skin using a skin treatment device comprising the drive unit and a second attachment, the second attachment comprising an epilation or a depilation unit;   
       wherein the drive unit can operate at a first preset speed and the preset speed is used in both steps. 
     
     
         10 . The method of  claim 9 , wherein the drive unit can additionally operate at a second preset speed. 
     
     
         11 . The method of  claim 9 , wherein the skin treatment step is carried out about 24 to about 72 hours before the body hair removal step. 
     
     
         12 . The method of  claim 9 , wherein the skin treatment step is carried out about 60 minutes to about 1 minute before the body hair removal step. 
     
     
         13 . The method of  claim 9 , wherein the first attachment comprises a first gear box and the second attachment comprises a second gear box and the second gear box provides a gear reduction of at least about 1 to about 2.5. 
     
     
         14 . A kit comprising a drive unit, a first attachment and an second attachment, the first attachment comprising a brush, the second attachment comprising an epilation or a depilation unit, wherein the first attachment comprises a first gear box and the second attachment comprises a second gear box and the second gear box provides a gear reduction of at least about 1 to about 2.5.
