I love skin care samples, like name brand(high end) when someone has those then i bid high if i have it. i really love isomers on shop nbc...she is a chemist along with her husband. most everything is serums. if you stay with the products you skin will look like ababys face. i was 59 within 4 months my skin looked as good as when i was in my thirties..... thanks she was the first person that had serums.....now i see them in department stores. this stuff works better than anything i've ever used.
