I have recently started using salt bars, and I have found that they help quite a bit with my rosacea. Even better, they have helped tremendously with the rash on my husband's back! We have been to the dermatologist many times, and although the ointment he gave us keeps it somewhat in check, it has never cleared after a year's use. He is wheelchair bound, and the derm told us it was more likely clogged pores. Hmpf. I am a nurse, and I was dubious that this rash was a result of that since it is somewhat "warty". It was biopsied, and the biopsy was showed only inflammation. Anyway, I digress. The salt bar used daily on his back has begun to dry up this rash quite a bit. Here is my actual question for those of you who use charcoal in your soaps. Does it actually seem to benefit in any way? No research has been done to prove that it helps with topical use. It seems a bit "trendy". I'm thinking of adding it to my next batch of salt bars if you guys think it might help.
