As a professional esthetician, understanding pH and its impact on skin is an integral part of education. Studies have shown that pH is not only an important factor in skin health, but it can also be one of the most important to understand. “The pH of the skin is one of the important physiological parameters of the skin. Changes in pH play a role in the pathogenesis of several skin diseases, including acne. “

In fact, skin problems like eczema, redness, dry patches, acne, oily shine, psoriasis, and early signs of aging all indicate that your skin’s pH is out of balance. The main manifestation of all these skin problems is a damaged skin barrier due to an imbalanced pH, which means that maintaining the proper pH of the skin is the primary responsibility of the skin care professional to maintain the skin barrier.

Understanding pH and its relationship to the skin is not only about recognizing skin-related signs but also knowing which products have a high or low pH and why. This will review background information on pH and its relation to the skin barrier, but all estheticians are encouraged to learn more on this topic as it is a concern. continuously, constantly developing.

pH scale

pH stands for potential hydrogen and is a unit of measurement that indicates whether a substance is acidic, neutral, or alkaline. Alkali are sometimes called “bases.” Just like a thermometer and an inch of distance, pH measures the amount of acid or alkali in an aqueous solution. Only aqueous and/or water-soluble solutions can be acidic or alkaline.

A solution is acidic or alkaline depending on the number of positive hydroxide ions or negative hydrogen ions it contains (ion is an atom that has gained or lost an electron). If a solution has more positive hydrogen ions than negative hydroxide ions, the solution is acidic. If it has more negative hydroxide ions, it is alkaline. When a solution has equal numbers of hydrogen and hydroxide ions, it is neutral.

The pH scale ranges from 0 to 14 with 7 being neutral. Numbers less than 7 indicate acid while numbers greater than 7 indicate alkaline. The scale is logarithmic, which means that each step or number increases to a multiple of 10. pH 6 is 10 times more acidic than neutral 7; however, number 6 is 10 times less acidic than number 5, which will decrease within the average pH range of hair, skin and scalp. When you’re using products that have a pH of 6 or “just some” of your hair’s average pH, it’s actually 10 times less acidic. That is a big difference. For example, did you peel an orange and when the juice from the orange came in contact with your skin, did you feel a slight tickle? The The pH of an orange is approximately 2, which is only 3 steps away from the pH of your skin (4.5-5.5) but in reality it is almost 1,000 times more acidic than your skin.

At the top of the scale is 14, which is 10 million times more alkaline than 7. For example, lemon juice has a pH of 2.5, which is considered a strong acid. Diet Cherry Coke has 3.0, which is considered a weak acid. Distilled water has a pH value of 7.0, which is considered neutral, although more alkaline than the ideal pH of the skin. Toothpaste has a pH value of about 8.5, while ammonia, a strong alkali, has a pH value of 12.5. Remember that a neutral pH is 7, with anything higher being alkaline and anything lower being acidic. For skin, however, the pH scale tends to be a bit broader, with acidity ranging between 4 and 7.

However, there are a number of factors both internal and external that can affect the pH of the skin. These include age, skin type on the body, genetic factors, sebum and skin moisture. Research has found that the pH of the skin can affect the barrier function which, in turn, can lead to many problems.

The skin barrier depends on the ability of the skin to retain moisture and the organization of lipids within the skin. The stratum corneum barrier is created by a process that involves a number of pH-dependent enzymes that have an optimal range between 4.5 and 5.6, which are then involved in the synthesis of ceramides, the components important of the skin fence. Studies have shown that elevated pH in normal skin creates a disturbed barrier. More, skin microbiota includes temporary, temporary and permanent species. Normal flora thrives optimally at acidic pH levels, while bad bacteria thrive at neutral pH levels.

Other factors that can affect the pH of the skin include air pollution, antibacterial products, seasonal changes, different humidity, cosmetics, detergents, sweat, tap water, exposure. too much sun and wind, aggressive treatments like microdermabrasion and acid peels, and Medical Treatment.

“Acid balance” and “pH balance” are two terms that are sometimes confused in the cosmetology industry. When a product says “pH balanced” it means that the pH is balanced at a certain number, but not necessarily between 4.5 and 5.5. Acid balance means balance in the acidic range of 4.5 to 5.5. Your duty as a professional esthetician is to use products that help maintain the skin’s acid balance between 4.5 and 5.5 acids.
