What pH level must glycolic acid be at for estheticians to use it?

Higher than 2.5
Higher than 3.0
Lower than 4.0
Higher than 5.0

The correct answer is: Higher than 3.0

Glycolic acid is an alpha hydroxy acid (AHA) widely used in skincare for its exfoliating properties. For estheticians to effectively use glycolic acid in treatments, it is important for the product to have a pH that allows for optimal efficacy and safety. A pH level higher than 3.0 is generally considered appropriate, as this range enables glycolic acid to exfoliate the skin effectively without being excessively irritating. At a pH lower than 3.0, glycolic acid can become too potent, which may lead to increased risk of irritation or chemical burns, particularly in sensitive skin types. Therefore, maintaining a pH above 3.0 helps balance effectiveness with safety in esthetic treatments. It allows for the desired exfoliation while reducing the potential for adverse reactions, making it a suitable choice for professional use in various skincare regimens. It's crucial for estheticians to be aware of these parameters to ensure they are providing safe and effective treatments to their clients.
