What pH level is not recommended for salon peels?

1. 5 to 7

2. 4 to 6

3. Less than three

4. Greater than eight

The correct answer is: Less than three

The pH level that is not recommended for salon peels is one that is less than three. This is because at such a low pH, the acidity is extremely high, which can lead to adverse reactions on the skin, including irritation, burning, and potential damage to the skin barrier. Chemical peels are effective at exfoliating and promoting skin renewal, but they must be formulated within a safe pH range to minimize the risk of negative side effects. Peels with a pH between 4 and 6 are generally considered safe and effective for use in professional settings. They strike a balance that allows for effective exfoliation while protecting the skin from excessive acidity. A pH above 7 indicates alkalinity, which, though less common for chemical peels, can also lead to ineffective results since most acids used in peels work best in a slightly acidic environment. Thus, pH levels less than three are avoided to ensure client safety and optimal outcomes during salon treatments.
