This review analyzed 30+ years of marine collagen research and found that marine collagen peptides can help reduce oxidative stress (free radical damage) and protect skin cells from aging. Studies showed benefits for wrinkle appearance and skin hydration when collagen was combined with hyaluronic acid, though most evidence comes from lab and animal studies rather than large human trials.

Researchers reviewed peer-reviewed studies published between 1991-2024 across four major scientific databases (PubMed, Cochrane Library, Web of Science, Embase), analyzing both lab experiments and human studies to assess marine collagen's anti-aging effects.
