What is the typical pH level of healthy skin?

Healthy skin typically maintains a pH level ranging between 4.5 and 5.5. This slightly acidic environment is essential for the skin's barrier function, helping to protect against pathogens and retain moisture. The natural acidity aids in the balance of beneficial bacteria on the skin's surface while inhibiting the growth of potentially harmful microorganisms.

Maintaining this pH range is crucial because deviations can lead to skin issues such as dryness, irritation, or infections. Products that promote or restore this pH balance are often recommended in skin care routines to support overall skin health.

Understanding the pH level of healthy skin helps nail technicians and others in the beauty industry provide appropriate care and treatment, ensuring that their practices align with maintaining skin integrity and health.
