Topical Corticosteroid Potency Guide

Topical steroids are classified into 7 potency groups (group 1 = super-high, group 7 = least potent). Vehicle matters — ointments are more potent than creams of the same drug.

Go-To Agents by Tier

TierDrugStrengthNotes
Low (group 6)Desonide0.05% cream/lotion/foamSafe for face, groin, axilla, children
Medium (group 4)Triamcinolone acetonide0.1% cream/ointmentWorkhorse for body eczema, psoriasis
High/Super (group 1)Clobetasol propionate0.05% cream/ointmentThick plaques, palms/soles; limit to 2 weeks

Practical Tips

  • Face/folds/children: Max group 6 (desonide); avoid fluorinated steroids
  • Scalp: Solutions, foams, or shampoos work best
  • Occlusion (wraps, diapers) increases absorption — step down potency accordingly
  • Atrophy risk increases with potency, duration, and occluded sites
  • Tachyphylaxis: Rotate or pulse to prevent tolerance with high-potency agents
