The first time I used this soap I instantly could feel the difference!!! It rinsed off CLEAN!!!! There was no residue from the soap left behind and my skin was not dried out! I spent waaaayyy too many years lathering with soaps and shower gels in a pretty bottle not realizing that most of them have formaldehyde as a preservative, along with several others toxins and metals. Sooooo glad I switched to Marvelous natural bar soaps!!!
