Skin is mildly acidic. The natural pH of most of our skin is between 4.7 and 5.75. A pH of 7 is considered neutral, and anything below that is acidic.
The skin's acidity is crucial for its health. It creates a protective barrier called the acid mantle, which helps to:
- Prevent infection: The acid mantle inhibits the growth of bacteria, fungi, and viruses.
- Retain moisture: The acidic environment helps the skin hold onto moisture, keeping it hydrated and supple.
- Maintain a healthy skin barrier: The acid mantle helps keep the skin's natural barrier intact, preventing irritation and dryness.
However, factors like environmental pollutants, harsh soaps, and certain skin conditions can disrupt the skin's pH balance. This can lead to problems like dryness, redness, and acne.
Therefore, it's essential to use skincare products that are designed to maintain the skin's natural pH balance.
