I am giving 3 stars
I am giving 3 stars because I personally think a product range with so much hype and with a huge price tag, ought to deliver the same level of service behind-the-scenes. Before parting with a huge sum of money for two products, I asked for advice. It took someone two weeks to respond with a very basic email, by which time I had already purchased as I needed a serum. And the advice was, well, not really advice. Shame.
