Which statement best reflects the scope of practice for cosmetologists in Ohio?

• A. They may diagnose medical conditions
• B. They may exfoliate stratum corneum cells only
• C. They may cure diseases
• D. They may perform invasive procedures

Answer: (B)

In Ohio, the scope of practice for cosmetologists centers on cosmetic skin care that improves appearance without diagnosing or treating medical conditions. Exfoliating the stratum corneum cells is a surface‑level cosmetic service that removes dead skin from the outermost layer of the epidermis, which is exactly the kind of non‑medical, non‑invasive care cosmetologists perform. The other options involve activities that require medical diagnosis, disease treatment, or invasive procedures, which fall outside cosmetology's scope. So exfoliating the outer skin cells best matches what cosmetologists are allowed to do.
