Milady Esthetics State Board Practice Test

In esthetics, what does a lower pH in a peel product indicate?

1. It is more alkaline

2. It is less effective

3. It is more effective on the skin

4. It neutralizes skin oils

The correct answer is: It is more effective on the skin

A lower pH in a peel product indicates that the formulation is more acidic. Acidic products, particularly those used in chemical peels, are generally more effective on the skin for exfoliation purposes because they can better penetrate the skin barrier and facilitate the shedding of dead skin cells. When the pH is lower, it enhances the efficacy of the active ingredients, prompting cellular turnover and resulting in a more effective treatment for conditions like hyperpigmentation, fine lines, and acne. In esthetics, a lower pH is often desirable because it reflects the acidity necessary for stimulating the skin’s processes. This is crucial in chemical exfoliation procedures since the action of acids leads to a peeling effect that promotes smoother, rejuvenated skin over time.
