What is the typical pH range for healthy skin?

Healthy skin typically has a pH range of 5.0 to 5.5, which is slightly acidic. This level is crucial for maintaining skin barrier function and overall skin health. The acidity helps to inhibit the growth of harmful bacteria and supports the presence of beneficial microorganisms on the skin's surface. When the skin's pH is maintained within this range, it can effectively protect against various skin conditions, such as dryness and irritation.

On the other hand, pH levels that are significantly outside this range can lead to compromised skin integrity. For example, a higher pH (more alkaline) can disrupt the acid mantle, leading to skin dryness and increased susceptibility to infections, while a lower pH (more acidic) can result in irritation and discomfort. Understanding that a balanced skin pH promotes optimal skin function is essential for effective skin care and aesthetic practices.
