PSB Bio Co., Ltd. is a biotechnology company specializing in the research and development of hair and skincare products using PSB (Rhodobacter sp.) microorganisms. PSB microorganisms are rich in natural amino acids, vitamins, ubiquinone, and minerals, helping to soothe troubled skin, maintain skin elasticity, and promote overall skin health.

Additionally, far-infrared radiation and low-wavelength properties enable effective decomposition of skin impurities and enhance the absorption of nutrients. This advanced bioactive ingredient helps prevent aging of the scalp and hair, inhibits harmful bacteria, and restores the skin's natural immune function.

We actively collaborate with the Department of Biotechnology at Jeonbuk National University to conduct continuous research and patent applications for microbial technology. Our company is committed to discovering and developing new microbial strains to create even more effective products. To support this initiative, we have established an in-house microbial culture and production system at the Jeongeup Advanced Science Industrial Complex.

Our business extends beyond cosmetics, encompassing the development of cosmetic ingredients and products, deodorization for agriculture and livestock, wastewater treatment, organic fertilizers, and animal feed. Additionally, we are expanding our presence in both domestic and international markets, including duty-free shops and exports.

With a vision to become a global leader in microbial biotechnology, PSB Bio Co., Ltd. continuously strives for innovation and excellence in the field.
