I have used their skincare regime for 20 yrs. feeling that I need a richer cream and I’ve been offered the chance to buy a professional size of this. Only thing is it’s £90. But my other professional sizes lasted over a year. My aunt used to be a beautician and she was one of the first to use Dermalogica in the UK. But she’s retired now so I can’t get the same sizes. Otherwise I would try it first.
