vinegar rinse for face

I heard if u mix vinegar with warm water and apply it with a cotton ball to your face it can restore the ph balance of your skin....and this prevents futher breakouts.  Does any one know if this is true?

I am a living witness to the positive outcome of using apple cider venegar as a toner on my skin.  It did get rid of those awful beneathe the surface pimples that were so hard for me to get rid of and attacked acne scars from way back then even out my skin tone...remember to dilute the vinegar 1 part vinegar to 3parts water.  it may tingle or sting a bit at first but thats normal, as long as you can stand it, if not add more water. Let us know how this works for anyone else who has tried it.
