What is the ideal pH level for healthy skin?

3.0 to 4.0
4.5 to 5.5
5.5 to 6.5
6.5 to 7.5

The correct answer is: 4.5 to 5.5

The ideal pH level for healthy skin is generally recognized to be between 4.5 and 5.5. This range is slightly acidic, which is essential for maintaining the skin's protective barrier. The natural acidity helps to inhibit the growth of harmful bacteria and fungi while supporting the skin's natural flora. This balance is crucial for preventing infections and skin conditions. Maintaining the skin within this pH range aids in the proper functioning of enzymes that are vital for skin repair and regeneration. A pH lower than 4.5 can lead to irritation and increased sensitivity, while a pH higher than 5.5 could result in dryness and a compromised skin barrier, making the skin more susceptible to environmental damage and infections. Therefore, the range of 4.5 to 5.5 is considered optimal for promoting skin health and resilience.
