      Hi Chloe – I think you may mean pH, as in the acidity/alkalinty measure. Our skin should be slightly acidic to fight off bacterial growth. pH 7 is neutral, halfway between acidic (pH 1- pH 6) and alkaline (pH 8- pH 14). As a reference, water is pH 7, vinegar is about pH3-4 and our skin is pH 5- pH6.

      Hope this helps
