Estheticians are permitted to use which of the following percentages of BHA?

• A. 5%
• B. 10%
• C. 15%
• D. 20%

Answer: (D)

The correct answer is 20%, reflecting the highest concentration of beta hydroxy acid (BHA) that estheticians are permitted to use in their practice. BHAs, such as salicylic acid, are commonly used for their exfoliating properties, especially in treating acne and oily skin. In the context of esthetic practices, the regulation regarding the maximum percentage of active ingredients like BHA ensures safety and efficacy in treatments. A concentration of 20% is often utilized in professional settings under the supervision of licensed estheticians who are trained to assess clients' skin types and conditions, thus providing tailored care. Lower percentages such as 5%, 10%, and 15% are often used in over-the-counter products available for home use, but these are generally less impactful compared to professional-grade products. The choice of a higher concentration, like 20%, allows for more effective exfoliation and improvement in skin clarity and texture, which is why it's permissible for trained professionals to use at that level during treatments.
