What are the components of fish maw?
The use of fish maw can actually be traced back more than 2,000 years. Ancient people, based on empirical knowledge, discovered various benefits of fish maw. Before the Ming Dynasty, in dynasties like the Tang Dynasty, fish bladders were already being used to provide professional health services.

1) Collagen: Fish maw contains up to 84% protein, most of which is collagen. Although there are slight differences depending on the fish source, the collagen content is generally above 80%.
2) Fish Maw Peptides
They primarily help alleviate damage caused by sun exposure. Previous researchers extracted fish bladder peptides using an enzymatic method and found that the repair rate of the fish bladder peptides produced under optimal extraction conditions reached 76-79%. This looks very promising because sun exposure is closely related to many skin problems, such as uneven skin tone, fine lines, and more.
3) Fish Maw Polysaccharides
Fish maw is rich in glycosaminoglycans, which can account for 8-10% of the dry weight of the fish bladder. Moreover, its moisturizing effect is quite good. Experimental data shows it directly surpasses classic moisturizers like sodium alginate and chitosan.
Fish maw is more suitable for beauty and skin nourishment. From collagen to fish maw peptides and fish maw polysaccharides, these three work synergistically to form a complete process, covering various aspects such as skin hydration and radiant texture.
