A 6-month-old female infant has a rash on the face. Which topical corticosteroid is most appropriate to prescribe for this patient?

• A. Hydrocortisone
• B. Betamethasone valerate
• C. Fluocinonide
• D. Mometasone

Answer: (A)

The key idea is using the gentlest effective topical steroid for an infant’s delicate facial skin. Infants have skin that absorbs medications more readily, and the face is especially permeable, so potent steroids can cause thinning, stretch marks, or even systemic effects with only small amounts or short courses.

Hydrocortisone is a mild, low-potency corticosteroid, making it the safest first choice for a 6‑month‑old with facial dermatitis. It provides anti-inflammatory relief while minimizing the risk of adverse effects on such sensitive skin.

Stronger steroids, like the higher-potency options, carry greater risks of thinning the skin and other local or systemic side effects in infants, so they are not appropriate as a routine facial treatment in this age group unless specifically directed by a clinician for a definite, monitored need.

Use should be short-term, applied as a thin layer, and not near the eyes or mucous membranes. If symptoms persist or worsen, consult a clinician for guidance or alternative therapies.
