Table salt, you wouldn’t think about it in getting rid of your acne.  But it’s one of the most natural ways to deal with it, without using any harsh chemicals or paying a lot of money for that reason.  My mom used to use salt to brush her teeth as a child, and it worked for that too for various reasons.  However, in terms of fighting your acne, it has some of the same useful properties.  First, it exfoliates.  In terms of brushing your teeth, it would be brushing away buildup in general.  But it exfoliates away dead skin cells that might well be clogging the pores and causing other damage.  If you use it a couple times per day, this can help you to fight your acne in that way.  In addition, it disinfects.  If you’ve ever actually spilled salt on an open wound, there’s a saying about that for a reason.  Like alcohol in some ways, it is actually disinfecting the skin, but it hurts!  So never do it if you actually have an open wound, unless of course you like to put yourself in pain.  Then there are other problems for obvious reasons.  But it’s cheap, it’s effective, and really it will get in there and do the job without actually harming your skin and without actually doing any other damage to you.
