Marine collagen edges plant-based options in the ageing fight: new evidence for skin health
A wave of new research summarized in recent reviews suggests that oral hydrolyzed collagen can offer modest improvements for skin ageing, including better elasticity, hydration, and a reduction in wrinkle depth after several weeks of use. The debate between marine collagen and plant-based collagen has sharpened as consumers increasingly seek “clean” beauty solutions that promise visible results. The current consensus from the best available evidence is nuanced: marine-derived collagen tends to show higher bioavailability and somewhat stronger skin benefits in many studies, while plant-based options are often marketed as collagen boosters that support the body’s own collagen production rather than delivering actual collagen peptides themselves. For Thai readers, this matters not only for personal health choices but also for the wider national conversation about wellness, ageing, and consumer protection in a fast-growing market for dietary supplements.
