The present invention relates to a method of producing a water-soluble collagen cosmetic composition by using torsional waves, the method comprising: a preparation step (S10) for preparing a liquid water-soluble collagen cosmetic composition containing collagen extracted from fish scales; an aging step (S20) for filling the cosmetic composition in a torsional wave-transmitting container and aging the same, the torsional wave-transmitting container capable of removing bad odors characteristic to collagen from the cosmetic composition, preventing putrefaction, and inducing water molecule clusters in the cosmetic composition to break down; and a collection step (S30) for collecting the cosmetic composition contained in the torsional wave-transmitting container upon completion of the aging step (S20). By aging the liquid water-soluble collagen cosmetic composition containing collagen extracted from fish scales in the torsional wave-transmitting container emitting far-infrared waves, anions, and torsional waves, the present invention can remove bad odors characteristic to collagen generated from the fish scales and prevent putrefaction due to the far-infrared waves and anions, and thus can facilitate good-quality collagen extracted from the scales to be easily applied to cosmetic compositions. Furthermore, the present invention can break down water molecule clusters contained in the collagen cosmetic composition to sizes of 60 Hz or less, thereby allowing collagen, together with the water molecule clusters, to penetrate down to the dermal layer of the skin, and thus can effectively supply collagen to the skin.COPYRIGHT KIPO 2020본 발명은 토션파를 이용한 수용성 콜라겐 화장품 조성물의 제조방법에 관한 것으로, 그 구성은 물고기 비늘에서 추출한 콜라겐을 포함하는 액상의 수용성 콜라겐 화장품 조성물을 준비하는 준비단계(S10);와, 화장품 조성물에서 콜라겐 고유의 악취를 탈취하고 부패를 방지하고, 화장품 조성물의 물 분자 클러스터의 분해를 유도하는 토션파 전사 용기에 화장품 조성물을 충진 숙성하는 숙성단계(S20);와, 상기 숙성단계(S20)가 완료되면 상기 토션파 전사 용기에 수용된 화장품 조성물을 회수하는 회수단계(S30);로 이루어지는 것을 특징으로 하는 것으로서, 물고기 비늘에서 추출한 콜라겐을 포함하는 액상의 수용성 콜라겐 화장품 조
