I discovered her when she wrote her first book many years ago - "Don't Go To the Cosmetics Counter Without Me". It is a break down on individual products - from over the counter to the most expensive product out there. She rates products on their effectiveness.
I have read all of her books cover to cover.
I then discovered her products about 9 years ago while I was dealing with my own acne. They work soooo well. Gentle cleansers, excellent bacteria killers, salicylic products for dealing with stubborn blackheads....
She is a wealth of knowledge when it comes to the beauty industry - her articles are incredible!!!
If you are suffering with any kind of acne check out her site through my site -
Feel free to ask me any questions you may have -
