Correct answer: B — Use an individual risk assessment rather than a blanket 6-month ban

Evidence does not support a universal 6–12 month delay for every superficial or fractional procedure after isotretinoin. Timing should reflect the procedure, skin type, active acne, healing history and clinician expertise; aggressive mechanical dermabrasion and fully ablative resurfacing warrant greater caution.
