A slurry is injected into a subject at a treatment site selected from the group consisting of (i) a deep subcutaneous fat layer, (ii) a superficial subcutaneous fat layer, and (iii) the deep subcutaneous fat layer and the superficial subcutaneous fat layer. Fat cells in the selected treatment site are ablated by the slurry. For example, the slurry is injected into (i) the deep subcutaneous fat layer only, (ii) the superficial subcutaneous fat layer only, (iii) the deep subcutaneous fat layer followed by the superficial subcutaneous fat layer, (iv) the superficial subcutaneous fat layer followed by the deep subcutaneous fat layer, or (v) the deep subcutaneous fat layer and the superficial subcutaneous fat layer simultaneously.在選自由以下組成之群的處理部位處將漿體注入受試者體內:(i)深層皮下脂肪層,(ii)淺層皮下脂肪層,及(iii)該深層皮下脂肪層及該淺層皮下脂肪層。該所選處理部位中之脂肪細胞經該漿體消除。舉例而言,將該漿體注入(i)僅該深層皮下脂肪層,(ii)僅該淺層皮下脂肪層,(iii)該深層皮下脂肪層,隨後該淺層皮下脂肪層,(iv)該淺層皮下脂肪層,隨後該深層皮下脂肪層,或(v)同時注入該深層皮下脂肪層及該淺層皮下脂肪層。
