Most soaps have a pH between 7, being neutral, and 10, which is quite alkaline. Studies have shown that when you apply a pH that is not the same as the skins pH of 4.5-5.5 it completely disrupts the acid mantle which is the protective layer of the skin.
One application of bar soap can disrupt your skin for over 6 hours leaving you at risk of increased bacterial colonization. If you are an acne prone skin this will result in an increase of acne bacteria making you break out. If you are not acne prone you are at risk of rashes and reactions.
All soaps are saponified, they leave a waxy residue on the skin. We don't recommend bar soaps on any skin regardless of the type. They are ALL alkaline. Even when advertised at a lower pH once they are tested these soaps present with a higher pH than advertised.
