According to official procedures, microbiology, stability, and challenge tests are conducted. To ensure rapid results, we chose a one-year shelf life test. Yeditepe University's R&D department conducted a one-year shelf life test, and the shelf life report was issued for one year. Due to the ingredients in products like creams, long-term testing is not possible. Therefore, and because creams are consumed quickly, we did not require a shelf life test exceeding one year.
