A student intern must have completed what percentage of their base license course outline before applying chemical treatments?

• A. 50%
• B. 70%
• C. 90%
• D. 100%

Answer: (B)

Interns can perform chemical treatments only after completing a substantial portion of their foundational esthetics coursework, ensuring they have solid knowledge of skin science, product chemistry, safety protocols, and client assessment. The board sets 70% of the base license course outline as the minimum before allowing chemical services, because this level provides enough theoretical grounding—including contraindications, patch testing, application and desensitization procedures, safety measures, and post-care—while still allowing supervised, hands-on practice as they continue their training. A lower threshold would risk safety due to gaps in essential knowledge, while a higher threshold would unnecessarily delay practical experience.
