Why is maintaining the skin's pH balance important?

Maintaining the skin's pH balance is crucial primarily for ensuring proper moisture retention and protecting the skin against pathogens. The skin has a natural acid mantle, which is a thin film of fatty acids and lactic acid that creates an acidic environment. This environment acts as a barrier that helps retain moisture, preventing dryness and dehydration. When the skin's pH is balanced, it supports the natural function of skin cells and helps to keep the skin supple and hydrated.

Moreover, a balanced pH is vital for the skin's defense mechanisms. It inhibits the growth of harmful bacteria and fungi, reducing the risk of infections and skin irritations. A disrupted pH can lead to skin conditions such as eczema, acne, and other irritations as the skin’s protective barrier is compromised. Thus, maintaining the skin's pH plays a critical role in overall skin health, supporting moisture balance and acting as a barrier against environmental aggressors.
