The first thing you should know is what we call skin pH , or hydrogen potential. It is a chemical parameter whose measurement tells us how acidic or basic a certain solution is . The neutrality value is 7, below are the acid values (the more acid the lower) and above the basic values (the more basic the higher).
Our skin, or rather the protective acid mantle that covers it and that is formed by the union of the aerial mantle (layer of water vapor and carbon dioxide that is released from the metabolism of cells) and the epicutaneous emulsion (or hydrolipidic film ), has a certain pH. Specifically, it is an acidic pH that varies under normal conditions between 4.5 and 5.9.
The hydrolipidic film is formed by the mixture of the secretions of the sweat glands (sweat) and sebaceous ( fatty acids , squalene and ceramides) with the products from the keratinization of the cells of the stratum corneum.
The substances that give are mainly lactic and urocanic acids, which are eliminated by sweat, and fatty acids provided by the sebaceous gland .
WHY IS THE ACIDIC PH OF THE SKIN IMPORTANT?
Variations in the pH of your skin cell can cause pathologies . For example, a more basic pH than normal can cause itchy skin, so it is important that we know the pH we have . At an inappropriate pH, we lose water and dehydration occurs.
The increase in pH also produces an inadequate functioning of the enzymes necessary for the defensive function of the skin to be carried out correctly.
On our skin, in the acid mantle there is an important colonization of microorganisms that form the skin's natural microbiota . These microorganisms begin to appear at the same time of birth and remain -with certain variations- in equilibrium while the pH of the skin is in the usual acidic values, hovering around pH 5.5.
But if there is an increase in the pH value, that is, if the skin becomes alkaline for a time , the defensive function will not work correctly and the growth of other types of microorganisms that are, or may be, harmful and could produce some pathology or the appearance of infections .
FACTORS THAT CAN ALTER THE PH OF YOUR SKIN
There are different factors that can lead to an alteration in the normal pH values of your skin:
CLEANING:
The how and with which you carry out the daily hygiene of your skin is very important in maintaining an adequate pH in the skin. https://skincell-pro.info/
