What is a ph balanced soap?
“pH balanced” means that the level of acidity of the soap (which is measured in units called pH) is balanced to match that of the skin.
The pH scale goes from 0 (very acid) to 14 (very alkaline), with 7 being neutral (like water). Healthy skin is typically around pH5.5 (i.e. slightly acidic) whereas normal soap is alkaline. The idea is that by removing the alkakinity, the soap will be kinder to your skin. Whether this is true or not is open to question.
