The use of fish maw can be traced back more than 2,000 years. Long before the Ming dynasty—and by the Tang dynasty at the latest—people had developed traditional ideas about its dietary and health-related uses through experience.
1) Collagen: The protein content of fish maw is as high as 84%, and most of it is collagen. Although different fish sources vary slightly, overall, the collagen content is over 80%.
2) Fish maw peptides
The article associates fish-maw peptides with reducing sun-related damage. It cites an enzymatic-extraction study that reported a 76–79% repair rate under the study's optimum conditions. Such laboratory findings do not by themselves establish a skincare effect from eating fish maw.
3) Fish maw polysaccharides
Glycosaminoglycans account for a reported 8–10% of the swim bladder's dry weight. The article cites experimental data in which their moisturising performance exceeded that of sodium alginate and chitosan; this laboratory comparison should not be read as a proven benefit from consumption.
The article links collagen, fish-maw peptides and fish-maw polysaccharides into a proposed skincare narrative covering hydration and radiance, while the evidence cited is ingredient or laboratory research rather than proof of outcomes from eating fish maw.
