The present invention relates to a multi-coloured cosmetic production method using a side injection technique and a wet powder for producing multi-coloured colour cosmetics, and to a device for the same. Provided is a multi-coloured cosmetic production method which uses a side-injection technique and a wet powder, comprising: a multi-coloured powder filling process in which the inside of a powder filling mould, which is divided into a plurality of spaces, is filled with wet powders of various different hues by spraying with a side injection technique a multi-coloured powder discharge process in which the multi-coloured powders filling the inside of the powder filling mould are discharged into a container and a multi-coloured powder pressing process in which the multi-coloured powder which was discharged into the container is pressed such that gaps between the multi-coloured powders come into intimate contact due to the pressing. Also provided is a multi-coloured cosmetic production device which uses a side injection technique and a wet powder, comprising: a powder filling mould of which the inside is partitioned into a plurality of partition spaces to form a plurality of powder filling parts each of which is formed with a plurality of powder spray ports such that wet powder can be supplied from the side by spraying with the side injection technique and upper and lower water-fraction absorbing members which are positioned on the top part and towards the bottom of the powder filling mould. Consequently, because powders of multiple colours and respectively different forms are shaped in a single process, the production process is made more straightforward and production is made easier, and the configuration of the device is simplified such that productivity is improved and costs are markedly reduced.본 발명은 다색의 색조 화장품을 제조하기 위한 습식 파우더를 이용한 사이드 인젝션 방식의 다색 화장품 제조방법 및 그 장치에 관한 것이다.종래의 다색 화장품을 제조하기 위해서는 픽커의 작동에 의해 판상의 화장품 재료를 소정 형상으로 커팅한 후 용기 내에 각각 다른 색상 및 형상으로 조합하도록 하고 있으나, 이
