I was really pleased to receive the Liberty advent calendar as a gift last December and have been working my way through the products over the past year. There were several similar products e.g. more than one moisturiser, several serums etc so I used one of each from start to finish rather than opening/using several at the same time. I'm a bit disappointed to find that two of the moisturisers seem to have gone off even though they weren't opened until now. The Zelens Emulsion D and the Votary nutrient cream smell rancid or certainly unpleasant. I know these types of product often contain fats and active ingredients that go off after 6/12 months but I'd hoped to use all the items up by Christmas before possibly getting another advent calendar. Now not sure it's worth it. Has anyone else had this problem?
