How do topical corticosteroids work?

These medicines act mainly where they are applied. The strength, formulation, body area, and condition affect how much medicine is appropriate. They may help settle eczema flares, some rashes, and psoriasis-related inflammation, but they do not remove every underlying trigger.

Apply a thin layer to the affected skin according to the prescribed schedule, and wash your hands afterward unless your hands are being treated. Avoid the eyes, broken skin, and covered areas unless a clinician has specifically advised this. Do not extend treatment or use a stronger product without review.

Seek medical advice if the rash spreads, becomes painful, develops pus or blisters, or does not improve as expected. Prompt care is needed for facial or eye involvement, breathing symptoms, or swelling of the lips or tongue.

Ask which strength suits the affected area, how long to use it, and whether a moisturiser or treatment break should be part of the plan. Mention any history of recurrent infections or sensitive skin.
