Please don't buy this book. Albert Kligman was responsible for the worst human rights violation since Nazi Germany. He tested unsafe chemicals on unsuspecting prisoners in Holmesburg and has never apologized for the hundreds of lives he ruined for the sake of his own financial gain. Human lives were lost. Immense pain and suffering were endured for the sake of cosmetic testing. Ask yourself if anti-aging cream is worth such a high price. Kligman is a disgrace to medical science and his books should be banned. Please spend your money on something worthwhile, not a book on cosmetics.
