We would not recommend using any of our products after the expiry date that is printed on the packaging. This date is the longest date by which the product should be used safely in month and year format.
We will hold substantiating data to show that the product is efficacious up to the declared expiry date, but beyond this date, we have no data to prove that the product would be effective. Therefore, we cannot recommend or confirm that any product is effective after the printed expiry date.
