Isoderm Soap Free pH5.5 Baby Liquid Cleanser 250ml Isoderm is non-alkaline and soap-free sharing the normal pH value of healthy skin at 5.5. Conventional soaps though effective are alkaline in nature and can interfere with the skins natural pH level. We need our skins natural acidic barrier to protect our skin against environmental factors and infections so if our skin loses its acidic pH it will become vulnerable to allergies and infections.
