The pH 5.5 Difference
Sebamed products are aligned with the pH-value 5.5 of healthy skin. This promotes the natural protection function of the skin’s own protective acid mantle and makes an effective contribution to prevent drying out, harmful environmental influences and pathogens.
What is pH
pH is short for the Latin term potentia hydrogenii and means hydrogen ion concentration.
The pH value serves to distinguish acids and lyes from each other and to mark their strength. Everything that contains water has a pH value that can be measured anywhere on a scale from acid too alkaline.
Our skin can also be assigned a pH value since the hydrolipid film on the skin surface contains water. For about one hundred years, it has been known that the skin is slightly acidic. Modern measuring methods resulted in an average pH value of 5.5.
The Acid Mantle
The importance of this acidic property of the skin surface is expressed in the so-called “protective acid mantle”. It has the task of defending against harmful microorganisms and negative environmental influences, thus protecting the skin from infections, irritation, allergy and drying out
Why No Soap?
For thousands of years, soap has been the most common washing agent, however, traditional soap is alkaline, with a pH value of anywhere from 5-12.
Using soap can change the skin’s natural pH, deplete moisture and lipids from the skin, and damage the protective acid mantle – which may lead to irritation, stinging, and further stress to sensitive skin.
