Never used the serum but have got advanced skin repair eyes (comes in smaller brown bottle) which I stole from my mum about 8 years ago.
Swear by it - I have no eye bags or wrinkles, it seems to have kept them from bay.
Texture of eye stuff very nice - somewhere between a serum and a waxy cream. Lasts bloody ages as well.
Am considering treating self to face serum but I spend a fortune on potions and make up as it is, and think skin is still good enough for a couple of years on moisturiser and sun block.
