What is a characteristic of healthy skin?

High alkalinity
Very dry
Slightly acidic
Extremely oily

The correct answer is: Slightly acidic

Healthy skin typically has a slightly acidic pH, which is crucial for maintaining the skin's barrier function and overall health. This mildly acidic environment helps to inhibit the growth of harmful bacteria and fungi, while also allowing beneficial microorganisms to thrive. The natural acidity of the skin is usually in the range of 4.5 to 5.5, which supports the function of enzymes that help with skin cell turnover and the maintenance of moisture levels. High alkalinity can disrupt this balance and lead to various skin issues, such as increased susceptibility to infections or irritation. Very dry skin indicates a lack of moisture, which can compromise the skin's barrier function, leading to more serious conditions. Meanwhile, extremely oily skin can signal overproduction of sebum, which may also lead to acne and other complications. Therefore, the characteristic of healthy skin being slightly acidic is vital for its protective and functional properties.
