BKJ Co., Ltd. is a dynamic cosmetics manufacturer committed to the mission of “pursuing healthy beauty.” Leveraging cutting-edge K-bio technology and innovative ideas, we specialize in producing high-quality skincare products, beauty devices, and medical equipment using our proprietary plant-based fermentation techniques. Our flagship brand, TuneTune—meaning “to arrange and harmonize”—offers skincare solutions grounded in our unique fermentation methods to promote balanced, radiant beauty.

We have secured patents and trademarks in over nine countries including Korea, Japan, and the United States, and completed registrations with the U.S. FDA under MoCRA and Japan’s PMDA, strengthening our global credibility. Our products are available on major EC platforms such as Amazon, eBay Japan, Shopee, and Coupang, and we’ve even expanded into the U.S. Department of Defense’s AAFES. In 2025, we proudly joined the Korean Pavilion at Expo 2025 Osaka and entered megamalls in Thailand and Hanoi, continuing our mission to introduce K-beauty innovations to the world.

At BKJ, we are dedicated to providing sustainable beauty to people everywhere through our continuous innovation in fermentation science.
