Eternal Ink implemented a third-party validation study to confirm the effectiveness of their sterilization process. The resulting microbiological testing data clearly demonstrates, with statistical confidence, Eternal Ink provides a sterile tattoo ink.
For continued quality control, Eternal Ink performs on-going quarterly dose-verification testing studies. The tests ensure the validated radiation sterilization dose continues to remain effective at killing microorganisms. The test results provide the sterility assurance level (SAL) validating Eternal Ink as sterile.
