Without destroying the molecular structure by high temperature, film type products represent the world’s first exclusive manufacturing method by Thanks Ai

This premium product contains high quality collagen extracted from the nasal cartilage of exclusively selected natural salmon in Hokkaido, which is well-known for its richness in nature. Collagen is the most abundant protein in human body, found in skin, bones, muscles, and tendons. It forms a scaffold to provide strength and structure. Our technology ensures that the molecular structure of collagen is not destroyed by high temperature and its activity and function is preserved to the fullest. Furthermore, by using our multinational patented extraction technology, the collagen content can achieve a purity as high as 75%.
