What is the pH of the skin
Ph is used in Chemistry as a measure of degree of acidity or alkalinity of an element normally evaluated in its liquid state. In the case of the skin it is usually useful to know what hygiene or beauty products tend to be or not the most appropriate, and which ones can harm us.
It is also true that this question will depend on the type of skin of each one, since a person with sensitive skin is not the same as someone who does not have it so sensitive.
In a more intelligible way, we will define the pH as the measure that determines the degree of acidity or softness of a product.
The ph contains a certain hydrogen potential and its amount indicates if what exceeds the medium it measures are hydrogen or oxygen.
Normal pH values of the skin
The skin in this case contains a pH between 7, marked as the ph-neutral at birth and between 5.5 and 6 in adulthood. For example, if a product contains a pH lower than the neutral pH, it turns out to be a ph neutral acid , because the hydrogenions predominate and if the ph is greater it is more alkaline.
Therefore, the components used for hygiene, especially soapy ones, usually contain a pH of 7.5 to 8, since the simple application of the product allows the pH of the skin to rise to 7 and 7.5. Because of this we advise to apply a product that contains a lower level ph.
However, if the total application of the bathroom products they do not maintain a pH exactly like the one of the skin, we should not be alarmed because after a period of time the same ph of the skin returns to recover and maintain its constant pH.
To conclude, we will mention that not only the skin contains the ph value, but also the food that we eat every day contains its own ph value and other elements such as hair , the nails and mouth also contain their own ph.
