Collagen is a kind of biological macromolecule material, which is a white, opaque and unbranched fiber protein. According to "Peptide Nutrition" (teaching material of Department of nutrition and food hygiene, School of public health, Peking University), collagen with molecular weight below 1000 daltons can be directly absorbed by human body without decomposition, which has obvious effect on oral absorption and external skin care.

The company's collagen is a small molecular product hydrolyzed by a variety of enzymes from tropical pollution-free tilapia scales or deep-sea cod skin.
