I LOVE and actually buy this stuff, rare words from someone who mostly relies on drugstore makeup and skin care, especially when on sale.
It was from Paula's books (lent to me by a friend) that I learned about sunscreen and much more, information that was not--sadly--featured in the mainstream press. I even told a friend with skin cancer a thing or three about sunscreen ingredients, all from Paula. Sadly, the friend's pricey dermatologist did not divulge the info.
Anyway, every month Paula has some kind of sale or other. I am mentioning the current sale ($3.00 shipping) because there is a one-week bonus. With the code SEPT15, you get 15% off too.
She has a money back guarantee.
