I bought some 'wish upon a jar' from Soap and Glory the other week because it was a third off and I was feeling rubbish.
I use Clarins because I love it and I am lucky that my Birthday and Christmas are 6 mths apart so I can have it as presents.
But this stuff is bloody ace. I have a problem with flaky nose syndrome and at this time of the year even my lovely Clarins cant sort it out.
One day of using this and it went YAY.
You can use it as moisturiser or under you own day and night cream. You use it for 21 days once a 'season' (or every three months in normal speak).
I was a bit 
but gave it a go because I was bored and it was cheap.
I think its brilliant. I recommend to any flakey faced mumsnetters out there. I dont work for S&G honestly.
