What is necessary for a peel product to be effective?

1. The acid must have a pH higher than the skin's pH

2. The acid must have a pH equal to the skin's pH

3. The acid must have a pH lower than the skin's pH

4. The acid must have a neutral pH

The correct answer is: The acid must have a pH lower than the skin's pH

For a peel product to be effective, the acid must have a pH lower than the skin's pH. The skin typically has a slightly acidic pH, generally around 4.5 to 5.5. When a chemical peel is applied, the lower pH of the acid solution allows it to penetrate the skin more effectively, promoting exfoliation and skin cell renewal. This acidic environment aids in the process of breaking down the bonds between dead skin cells and the underlying layers. Utilizing a peel with a pH lower than the skin’s pH enhances the product's ability to achieve the desired therapeutic effects, such as improved skin texture, reduced signs of aging, and an overall brighter complexion. In contrast, a peel product with a higher, neutral, or equal pH would not provide the same level of exfoliation and may not yield the intended results.
