I bought the pcmc silver jar from Debenhams a few months ago, they were having their 10% of cosmetics day, so a better price than Q.
I noticed that it seemed a bit different this time, smell was similar but not quite the same, that was the main thing, but texture was also slightly different. It was the normal one not the richer one. It's okay and I've nearly used it up but won't buy again as it's doing nothing for me really.
I've just come across the reviews for this on the Q Elemis site, several reviewers are saying the same thing, that it's different. One posted that she contacted Elemis direct and they confirmed that the formula has changed. Others have posted that it is causing skin problems now, when they had been using it for years.
They should mention this update of formula on Elemis hours, but I don't think they have.
