I've been taking msm for about 15 years. It hasn't done anything for my skin. I am enjoying my results with Prosacea so far. I've spent hours on rosacea forums. Not everything works for everyone. A lot of people are having good results using Afrin on their red areas. But on some people it stops working and their symptoms come back worse.
I think I will give the Alpha Lipoic Acid a try. I read up on it last night and it sounds pretty awesome.
