They look interesting, but could also be a lot of hot air. I am reading his new book called "The New Science Of Perfect Skin " and it has some interesting information. Unfortunately, the book seems to be a thinly veiled attempt to push his products. It is very similar to Dr. Denese's book, except Dr. Yarosh promotes different "miracle" ingredients.

Dr. Baumann, have you ever heard of this doctor or line of products?
