This book lays out Dr. Lancer's LAncer Method in it's entirety! It's truly the fountain of youth covering everything from skincare to diet, exercise and breathing techniques! I love it and have been reading a chapter a night until I have the bits I want to incorporate memorized. I learned so much on the education side too of what is causing my acne and wrinkles. Def worth the $25 purchase! My other fave thing about this book is the budget product recommendations in case you are not able to afford the Lancer skincare products... Shop Younger by Dr. Harold Lancer Book, The Method Deluxe Starter Kit, and the full Lancer Skincare Collection at Bergdorf's.
