What is the maximum glycolic acid percentage an esthetician can use for a chemical peel?

30% or lower
20% or lower
40% or lower
10% or lower

The correct answer is: 30% or lower

The maximum percentage of glycolic acid that an esthetician can safely use for a chemical peel is 30% or lower. This limit is established to ensure the safety and efficacy of the treatment while minimizing the risk of adverse effects, such as excessive irritation or chemical burns on the skin. Glycolic acid is an alpha hydroxy acid (AHA) that is commonly used in cosmetic and skin care treatments due to its exfoliating properties. When used in higher concentrations, the risk of complications increases, making it vital for licensed professionals to adhere to safety guidelines and regulations. In Wisconsin, state board regulations typically dictate the allowable concentrations for estheticians to ensure that they perform safe procedures. Thus, the choice of 30% or lower aligns with these regulations, promoting responsible practices in the field of esthetics.
