Hopefully one of you lovely geeks that use Elemis can help me out with this question

My friend has asked me to find out about an Elemis product called Pro Collagen Quartz Lift Serum, as her mum has asked for some for her birthday, not a problem, but when she went to buy some discovered it cost £95 !

She can't afford to spend that much so wants to find an Elemis substitute for this product, What do you suggest ?

Also I would like to know more about this serum if possible, ive had a look on a few websites but not that much info on it.
