According to the Cosmetic Act, the shelf life must be determined based on scientific evidence and stability testing. If a product has already been labeled with a 24-month shelf life, unilaterally modifying the label to indicate 30 months without undergoing the proper legal procedures constitutes falsification or alteration of labeling.
Such conduct is a violation under Article 15, Subparagraph 9 of the Cosmetic Act. Therefore, it is prohibited to arbitrarily change the labeled shelf life once the product has been released with the original indication.
