Our Factory

Located in Tai Po, Hong Kong, Keystar Therapeutics’ existing factory came into operation in 2011. With improved facilities, upgraded equipment, refined processes, and ongoing personnel training, we exercise strict quality assurance measures to ensure our products meet the highest possible standards. From initial raw material inspection to final product packaging, all production and quality assurance processes take place in-house at this factory. Certified by Hong Kong’s Department of Health under the Chinese Medicine Ordinance (Cap. 549) and the Food & Environmental Hygiene Department under the Public Health and Municipal Services Ordinance (Cap. 132), this is where we proudly produce all of our products.
