Correct answer: B — Topical calcineurin inhibitor (Pimecrolimus 1% or Tacrolimus 0.03%) to manage the transition period

During topical corticosteroid withdrawal for perioral dermatitis, a rebound flare is expected as the skin adjusts. Topical calcineurin inhibitors (Pimecrolimus 1% or Tacrolimus 0.03%) serve as effective steroid-sparing transitional agents — they provide anti-inflammatory effect without perpetuating the steroid dependency cycle. They can be applied during the withdrawal phase to ameliorate the rebound. Oral Tetracycline (Lymecycline/Doxycycline) for 6-12 weeks is the primary systemic treatment for perioral dermatitis. Topical Metronidazole or Azelaic acid are additional topical options. The key principle: the topical corticosteroid must ultimately be withdrawn completely.
