Hello , I used this years ago. I had very severe psoriasis, which covered over 80% of my body. So, I would have tried anything. My first thought was how bad it smelled, now remember this was years ago. They might have improved it now. It had a very strong smell that stayed with you, even after a bath. I used it for a good few weeks and never saw any improvement. But like I said, this was a long time ago. The smell was like tar and motor oil. I can still smell it to this day. But, some people use it and have good results. How long have you had psoriasis? I am going on year 62. Tell us how the MG217 product works. Diane (Team Member)
