Paula Begoun has done us all a great service by writing such a well-researched and informative book. Never having read the earlier editions, I was drawn to this one due to some distressing experiences with sunscreen, moisturizer and concealer. She covers it all and then some! This book has a well coveted place near my favourite chair, from which I refer to it often. The cost of the book was easily recouped over a month or so of beauty product purchases. I really can't give it enough praise!
