"We’re disappointed to let you know about a safety issue we have discovered with Superskin™ Concentrate for Night 2ml, that our records show you have purchased from us.
We recently became aware that small traces of glass have been found in one batch of this product (batch number 6T). As a precautionary measure, we are recalling all products with batch numbers 6T, 6F and 6P and ask you to stop using it and dispose of it. The batch code can be found on the cap of the vial and on the outer sleeve".
They're actually offering a very generous refund, replacement or alternative if you register via the link in the email - obviously they know who's purchased it via the website, not sure what the arrangements are for Q customers.
I've opted for replacement, and they are sending a 10ml roller ball size, plus a free gift. Not a bad return, since the original 2ml size came as a freebie!
