The invention relates to a skin treatment device for removing indurations from the skin by means of an abrasive treatment, comprising a housing with a handle section (110), a skin treatment element (120) rotatable around an axis of rotation (101), and a protective rim. (130). The protective rim is at an angle greater than 120 ° but less than 330 ° about the axis of rotation such that the circumferentially polished surface protrudes from the protective rim in a region extending over an angular range of 30 ° to 240 °. The skin treatment element is partially surrounded circumferentially over the area.本発明は、研磨処理によって皮膚から皮膚硬結を除去する皮膚処理デバイスに関し、ハンドル区画（１１０）を備えるハウジングと、回転軸（１０１）の周りで回転可能な皮膚処理要素（１２０）と、保護リム（１３０）とを含む。保護リムは、円周方向研磨処理面が３０°～２４０°の角度範囲に亘って延在する領域内で保護リムから突出するよう、回転軸について１２０°よりも大きいが３３０°よりも小さい角度範囲に亘って皮膚処理要素を円周方向に部分的に包囲する。
