How to Use Hydrocortisone and Steroid Creams Safely

Strengths explained

Topical steroids range from mild (hydrocortisone 1%) to very potent (such as clobetasol). Stronger creams work faster for thick skin and stubborn rashes but carry more risk on thin skin. The face, eyelids, armpits and groin need the mildest options.

How to apply

1. Wash and dry your hands.
2. Squeeze out a line of cream from the fingertip to the first crease: one fingertip unit.
3. That amount covers an area about the size of two adult palms.
4. Apply a thin layer to the rash, gently, once or twice daily.
5. Use moisturizer separately, ideally 15 to 30 minutes apart.

Cautions

• Do not use for more than about 1 to 2 weeks without advice.
• Avoid on infected skin, cold sores, acne and fungal rashes (unless prescribed).
• Long-term use can thin skin, cause stretch marks and lighten skin color.
• Stop gradually after long use to avoid a rebound flare.

How we can help

If a rash is not improving, we look at it on video or in clinic, decide whether a steroid, antifungal or something else fits, and set a plan with the right strength and duration. See our skin health service.
