The only person who would spend that kind of money on my birthday/Christmas present would be my husband and if he presented me with deep wrinkle serum, it would go straight where the sun doesn't shine.
I may have loads of wrinkles but as I don't look at myself in the mirror so it don't bother me. Any anti wrinkle cream will be as useful as any other make-up to me. Much prefer to have the money to buy practical items like a non-stick frying pan.
