Sulfur springs can actually be one of the best things for your skin.  They are generally fairly warm, meaning it will warm up and release your pores to release other potentially harmful elements which is always a good thing.  I had to search out a good sulfur spring in my area, which was harder than I expected, and they say that it rejuvenates your muscles and keeps your skin younger as well.  But of course, its ability to kill bacteria and otherwise is definitely something to be considered to say the least.  This being said, the one thing I caution you about with any sulfur spring is the smell, they absolutely stink!  And frankly I would take a good bath with a good wash after just because it stinks!  There is no real contesting that.  But for all the smell, the results are good.  I honestly felt a lot better, my skin felt a lot better, and it’s not at all surprising to me that the Japanese samurai used it for relaxation after hard days of battle or that it was at first reserved for the elite while peasants later discovered it to use after long days of work in the fields.  All in all, you can use it now, they are all basically the same wherever you go.  But if you can find one in your area, I would definitely recommend it.
