For a skin care professional, understanding the basics of the structure of the skin is an absolute necessity. Because when you understand the skin, you can diagnose the condition, find the cause and build the most suitable skin care and treatment route for the customer.
Of the factors that affect the health of the skin, the imbalance of pH is one of the most important. So do you know about the pH of the skin yet? Don't miss the next post of Miss Tram Academy ok
Sharing About Skin's pH
1. What is the pH?
pH (short for Potential of Hydrogen) – is the unit used to determine the alkalinity/acidity/neutrality of any product or medium.
The pH is measured in levels from 0-14, the lower the pH, the more acidic the environment. And vice versa, the higher the pH, the more alkaline the environment. The neutral pH is 7 (aqueous medium).
2. The importance of pH balance on the skin?
Human skin has three main layers: epidermis, dermis, and dermis. In particular, the outermost stratum corneum of the epidermis will have an extremely thin film that creates natural moisture, helps protect the skin and prevents negative effects from the environment. This membrane is called Acid Mantle Membrane.
A healthy skin will have a Mantle Acid Membrane with a pH between 4.5-6.2. This mildly acidic environment will prevent harmful bacteria, prevent water loss and the effects from the outside environment most effectively.
So, what happens if there is an imbalance in the pH of the skin?
If this Mantle Acid Mantle is imbalanced in pH (too high or too low compared to the natural balance), the skin will be unprotected and quickly appear many serious problems on the skin such as:
- Too low a pH will cause the skin to secrete excess oil, clog and dilate pores, creating a favorable environment for acne to form.
- If the pH is too high, the skin is easily dry and rough, affecting the texture of the skin, causing the skin to quickly age and appear more wrinkles later.
- The skin is easily red, swollen and irritated by the effects of the external environment.
- The process of using cosmetics does not achieve optimal results, even causing irritation.
Note: Why Detoxify Skin.
3. What causes the skin to lose its pH balance?
Normally, the pH of the skin is directly affected by the following main reasons:
- Using inappropriate skin care products (with a pH that is too high or too low for the natural pH of the skin), causes the Mantle Acid Mantle to be broken.
- Improper skin care habits: washing your face too much, exfoliating too hard, rubbing your skin too much, using hot water...
- Unscientific diet (eating a lot of alkaline foods will increase the acidity of the skin, and on the contrary, eating a lot of acidic foods will increase the alkalinity of the skin).
While the Mantle Acid Mantle on the skin will heal on its own after a few hours, if there are many factors at play continuously this process can take up to several days. Therefore, to ensure that the pH of the skin is always balanced, it is necessary to take care of the skin properly and use appropriate cosmetics.
4. Some notes about the pH of cosmetics that skin care professionals need to know
- Skin cleansing cosmetics such as makeup removers and facial cleansers have an average pH of 5-6.
- Toners usually have a low pH, about 3.5 – 4.5 to balance the pH of the skin well.
- Cleaning products such as shower gel have an average pH of 6, soaps have a pH >7.
With other skin care products, depending on the skin condition, you should choose a cosmetic line with an appropriate pH. For example, acne and oil-control product lines will often have a high pH above 7.5, while product lines for dry skin often have a lower pH - only from 4.5 to ensure skin is not irritated.
The use of cosmetics with an inappropriate pH is considered one of the main causes of many skin problems. Therefore, when receiving customers, you need to ask clearly what skin care products the customer is using to give the best judgment and advice.
5. How to ensure the pH balance on the skin?
In order for customers to have a balanced skin pH, you need to build a reasonable skincare routine and advise customers to use appropriate skin care products. Therefore, after conducting dermatoscopy and skin type testing, build a proper skin care routine according to the following criteria:
- Do not use facial cleansers with a pH above 6.5, only wash your face with cleanser twice a day and use a soft cotton towel to wipe your face.
- Do not exfoliate more than twice a week and do not use products that are too coarse.
- Do not sauna more than 2 times a week and always adjust the sauna distance to avoid burns.
- Do not apply the mask more than 3 times a week, do not apply the face for too long is to choose the right ingredients/products for the skin condition.
- Always choose cosmetics carefully, pay attention to ingredients and origin to ensure the most suitable and safe for the skin.
- Limit changes in cosmetics continuously in a short time, making the skin not able to adapt and easily irritated.
- Always apply sunscreen to your skin.
In addition to practical skills, any skin care professional needs to master the basics of skin. This will help you have a better overview, thereby improving the ability to analyze, diagnose and provide the most accurate treatment for customers. So, always learn and hone a lot of skin knowledge to quickly become an expert.
