What is the natural pH range of human skin?

0-3
3-7
4.5-5.5
7-10

The correct answer is: 4.5-5.5

The natural pH range of human skin falls between 4.5 and 5.5, which is slightly acidic. This acidity serves several important functions. It helps to maintain the skin's moisture barrier, protects against harmful bacteria and pathogens, and aids in the overall skin health by supporting beneficial microbial flora essential for skin protection and healing. Maintaining this pH range is vital because fluctuations can lead to skin issues. For instance, if the skin becomes too alkaline (moving closer to the higher pH levels), it can result in dryness and irritation, making the skin more susceptible to infections. Conversely, a significantly lower pH level may lead to irritation and skin disorders. Overall, recognizing and maintaining the skin’s natural pH is crucial for estheticians and skincare professionals, as it impacts their approach to treatments and product recommendations.
