What is PH and why is it important to skin structure?
It performs an important function - it is a protective barrier between the body and the outside world.
The PH balance is often disturbed due to external aggressor factors (polluted air, temperature changes, chemicals, etc.), therefore, it is necessary to use skin nourishing products. A pH-based moisturizer or other skin care product restores natural defense mechanisms.
In a healthy state, the PH level of the skin ranges from 4.7 to 5.75. Any other indicator that is higher or lower than this parameter is considered as an imbalance - this diagnosis means that due to various factors, the outer layer of the skin has lost its function as a protective barrier, the skin has become prone to dryness due to a lack of water. Against the background of a chain reaction, corresponding symptoms appear (increased sensitivity, dryness, vulnerability to infections, diseases).
The pH level changes due to the following external factors:
- Change in air temperature;
- Polluted air;
- Hygiene is necessary, but washing too often is harmful;
- Cosmetics containing alkali;
- Chemicals.
The following internal factors are noteworthy:
- Genetics;
- Biological age;
- Hormonal changes.
