Provided in the present invention is a material which is produced by processing a material extracted from a plant seed using an organic solvent, and which is highly effective in promoting collagen production, promoting hyaluronan production, and diminishing the appearance of wrinkles. The collagen production promoter related to the present invention is characterized by being obtained through a process in which: an extracted material containing an oil component is extracted from a seed of a plant belonging to the family Cupressaceae and the genus Platycadus by using an organic solvent； part or all of the solvent is removed from the extracted material by distillation； an aqueous alkali solution having a concentration of 0.5-15 N is added and mixed； acid treatment is performed； and the resultant material is subsequently washed with water.본 발명은 콜라겐 생산촉진효과, 히알루론산 생산촉진효과, 섬유아세포 증식촉진효과 및 주름개선효과가 우수한 식물 종자의 유기용매 추출물의 처리물을 제공한다. 본 발명에 관한 콜라겐 생산 촉진제는 측백나무과(Cupressaceae) 측백나무속(Platycladus)에 속하는 식물의 종자를 유기용매를 사용하여 추출하여 유성성분을 함유하는 추출물을 수득하고, 상기 추출물의 용매의 일부 또는 전부를 유거한 후, 농도 0.5~15 N의 알칼리 수용액을 첨가, 혼합하고 이어서 산 처리 후 수세하여 수득되는 것을 특징으로 한다.
