Question

Estheticians may not use unbuffered alpha-hydroxy acids at concentrations greater than ___ percent;

Answer 1

Estheticians are restricted to using unbuffered alpha-hydroxy acids at concentrations no greater than 30 percent to ensure client safety and adhere to health regulations.

Step-by-step explanation:

Estheticians may not use unbuffered alpha-hydroxy acids at concentrations greater than 30 percent. It is important for safety and health regulations that estheticians adhere to this rule to prevent skin damage to clients. The use of alpha-hydroxy acids (AHAs) at higher concentrations without appropriate buffering can cause irritation, burns, or other skin injuries, and is therefore regulated in professional settings.
