The global marine collagen market is projected to grow from USD 1.14 billion in 2026 to USD 1.66 billion by 2031, registering a CAGR of 6.7%. Growth is being fuelled by rising demand for beauty-from-within, anti-aging, and skin-repair products. Marine collagen is increasingly used in skincare supplements and ingestible beauty formulations due to its high absorption and bioavailability. Consumers are also favouring clean-label, sustainably sourced ingredients derived from fish by-products. Asia Pacific is expected to emerge as the fastest-growing market, led by strong collagen consumption trends across Japan, China, and South Korea.
