The author was instrumental in the formation of the societies of plastic and aesthetic surgery, as well as in the creation of courses, journals and history books, which laid into the hands of those in want of learning, have become the means to relate them with the elements for recognizing beauty and to strive to create and recreate it precisely without falling back into past errors. Now, Mario Gonzàlez Ulloa, doctor and author, presents this book, fruit of his philosophical, historical and scientific meditation: a book to mark an essential durability of man - man or woman- who must give rules so that the yet to come century may be a new epoch of more tranquillity, more serenity and yet more peace of man with man. This book is one of the many ways of teaching. It is written to the young surgeon, to the mature and to the old one, so they may deepen into the roots, the philosophical essence, the integral process of man's withering and how to alleviate the appearance of the aging face.
