Why is maintaining skin acidity important?

Maintaining skin acidity is crucial primarily because it helps to prevent harmful bacteria from attacking the skin. The skin's natural acidity, often referred to as the acid mantle, plays a significant role in creating an environment that is inhospitable to pathogenic microorganisms. This thin, protective layer is composed of sebum, sweat, and lactic acid, maintaining a pH level that typically ranges from 4.5 to 5.5.

When the skin’s acidity is intact, it supports the skin’s natural barriers, which helps to fend off infections and effectively fights off the growth of bacteria, fungi, and viruses. An imbalance in skin pH can lead to disruptions in these protective mechanisms, increasing the risk of skin conditions such as acne, dermatitis, and other infections. Therefore, maintaining the correct level of skin acidity is fundamental for overall skin health and integrity.
