Glow Up for Success: Conquer the 2026 Wisconsin Esthetics Exam!

The maximum percentage of salicylic acid that an esthetician can use for a chemical peel is 20% or lower. This standard is established to ensure safety and efficacy during the chemical peel process. Salicylic acid is a beta hydroxy acid (BHA) known for its ability to exfoliate the skin, penetrate pores, and treat various skin concerns, particularly acne.

When performing chemical peels, it is crucial to adhere to state regulations and safety guidelines to minimize the risk of adverse reactions or complications such as excessive peeling, irritation, or scarring. By setting a limit of 20% for salicylic acid, regulatory bodies ensure that the treatment remains within a safe concentration that can still provide beneficial results without overwhelming the client's skin.

Higher concentrations may require a medical professional to supervise, as they can lead to more intense reactions and complications. Therefore, understanding the appropriate usage and concentration of chemical agents is vital for estheticians to practice safely and effectively.
