Dr. Marie has been making soap for almost 7 years now. She started selling her handmade soap less than a year ago, and she has been blogging a lot to explain why she is selling soap even though she is a PhD scientist. It took years of developing her soap making process to figure out how to make truly natural handmade soap. Even essential oils are not natural to her because they are highly concentrated components of plants that are never found so concentrated in nature. Sure enough, essential oils have caused serious problems on some people and they are unnecessary ingredients. In fact, Dr. Marie has found so many common ingredients in soaps that are not only unnecessary, but actually harmful. Soap manufacturers add these ingredients to their products for reasons that are unrelated to your health and may even be at the expense of your health. For example, soap makers add preservatives to give their products longer shelf lives. Fragrances are added to cover up the unappealing smell of cheap ingredients. Colors hide flaws. No wonder so many people have so many skin problems. Since skin is your biggest organ, your skin health is a very serious matter.
