What is the pH at the surface of normal skin?

3.0-4.0
4.5-5.5
5.5-6.5
6.5-7.5

The correct answer is: 4.5-5.5

The correct range for the pH at the surface of normal skin is between 4.5-5.5. This slightly acidic pH helps to maintain the skin's protective barrier and inhibit the growth of harmful bacteria. Options A, C, and D are incorrect because they either suggest a lower or higher pH, which can disrupt the natural balance of the skin and lead to various skin issues. The incorrect options may also lead to increased oil production, dryness, or irritation on the skin. Therefore, the ideal pH range for skin's pH is between 4.5-5.5.
