Buying at half price is great, worth £80? Totally not. Used for eight weeks now and not an iota of difference noted. You're better off buying and drinking 5 litres of supermarket water for just over £1 if you want to see an improvement in your skin.
Smells nice, feels nice and it does moisturise but if you want to spend £40 a month for younger looking glowing skin then this isn't it. Get some E45 cream and drink more water.
