…to my previous post. For those who were wondering how could salt work on acne, it’s about the simple water movement you learned in high school! Let me refresh you a bit :)

What happened when you put some salt solution on your acne is a classic hypertonic solution. Now if there were bacteria in a surrounding where salt is the solute (which makes the concentration higher outside of the bacteria cell than the inside) the water would diffused out of the bacterial cell (water leaves the bacterial cell), causing the cell to shrivel and die.

…and that’s how salt works killing the bacteria that lead to acne! :)
