L'Oreal Revitalift Serum
The Chanel serum is sublime, yes. However, I get through serum very quickly and I simply can't justify spending £70 every six weeks. Yet again I ventured forth to find something I could live with and I found this in Boots. Annoyingly I now can't see it on their website but I am confident it still exists as it's on the L'Oreal site.
This has broadly the same consistency as the Chanel, it smell perfectly nice, it sinks in and feels like it's doing you good. It costs about £20 but I don't even think it lasted me three weeks. It's not like I bathe in the stuff for heaven's sake! Also, I can see there is some left at the bottom but it's not coming out of the pump. Annoying. Note to bottle designers: stop doing this.
Despite all that, I do like it a lot and may buy another bottle until I win the lottery and can live in Chanel glory forever more.
