The present invention provides an improvement of a acne-removing cosmetic device, which comprises a main body, an oscillator, a power supply device and a pressure bar. The main body has an accommodating space therein, and has a slot for connecting the inside and outside of the accommodating space. The pressure bar has opposite inner and outer ends, the inner end is positioned in the accommodating space, and the outer end is protruded from the front end of the main body through the notch, and the oscillator is disposed in the accommodating space of the main body, and the power supply device Providing electric power, the oscillator can provide a high-frequency vibration pre-pressing rod； wherein: the positioning space is provided with a positioning mechanism, and the pressing rod is positioned on the positioning mechanism, so that the pressing rod can be quickly assembled and disassembled in the positioning mechanism. The purpose of the above.本創作係提供一種除痘美容器之改良，其係包含一主體、一震盪器、一電源裝置及一壓棒，主體內部形成有一容置空間，且具有一連通容置空間內外之槽口，壓棒其具有相對之內端、外端，令內端係定位於容置空間中，外端則是經過槽口而突出主體前端，震盪器係設置於主體之容置空間內，由電源裝置提供電力，令震盪器可提供一高頻震動予壓棒；其特徵在於：該容置空間內設有一定位機構，以壓棒定位於定位機構上，達到壓棒可以快速組裝及拆卸於定位機構上之目的。
