SOUTH KOREA SEAWEED MARKET TRENDS:
Expansion of seaweed exports
The expansion of seaweed exports is positively influencing the market in South Korea. According to the information provided by the Korea Agro-Fisheries & Food Trade Corporation (aT), during Q1 2024, South Korea's seaweed exports achieved record levels, witnessing an impressive 21.1% rise in export value compared to Q1 2023. As the international demand is increasing for Korean seaweed products, such as roasted seaweed snacks, dried sheets, and seaweed-based health supplements, local producers are responding by scaling up cultivation and improving processing methods. Export markets like the United States, China, Japan, and Southeast Asia are showing strong interest in the Korean seaweed due to its taste, nutritional value, and association with Korean cuisine. This export momentum is encouraging local farmers and companies to adopt more efficient and sustainable farming practices to meet worldwide standards. Government support through trade agreements, quality certifications, and marketing campaigns is further enhancing the competitiveness of Korean seaweed in international markets. The rising popularity of Korean food culture also plays a role in increasing overseas interest. As more people worldwide are seeking healthy and low-calorie plant-based snacks, Korean seaweed is becoming a preferred choice, boosting export volumes. Companies are diversifying their product lines to suit foreign tastes, driving research and development (R&D) activities in the sector. Export success is contributing to steady income for coastal communities and promoting regional economic development.
Growing applications in cosmetic and skincare products
Rising applications in cosmetic and skincare items are fueling the South Korea seaweed market growth. People are showing strong preferences for natural and functional ingredients, and seaweed fits this trend with its rich content of vitamins, minerals, antioxidants, and moisturizing compounds. Seaweed extracts are widely used in creams, masks, toners, and cleansers due to their hydrating, anti-aging, and skin-soothing properties. As the worldwide popularity of K-beauty is increasing, international cosmetic brands are adopting Korean seaweed-based formulas, further boosting domestic production and innovation. South Korean skincare companies continue to develop seaweed-based items to stay ahead in the competitive beauty market, catalyzing steady demand for high-quality, locally sourced seaweed. Coastal farmers are benefiting from contracts with cosmetic manufacturers, ensuring consistent income and encouraging sustainable farming practices. The beauty industry’s focus on clean and eco-friendly ingredients aligns with seaweed’s image as a natural and renewable resource. As the thriving cosmetic industry continues to favor ocean-derived ingredients, seaweed maintains a strong position as a key resource, reinforcing its importance in South Korea’s economy. According to the IMARC Group, the South Korea cosmetics market is set to attain USD 12,712.7 Million by 2033, exhibiting a growth rate (CAGR) of 5.3% during 2025-2033.
