A moderately potent topical corticosteroid
Clobetasone
A moderately potent steroid cream for eczema flares; used as a thin layer in short courses, with care on the face and skin folds.
What is Clobetasone?
Clobetasone is a moderately potent topical corticosteroid (steroid) cream or ointment used to calm inflamed, itchy skin in conditions such as eczema and dermatitis. It is applied as a thin layer to the affected areas in short courses to settle a flare. Using it sparingly and for short periods, with extra care on the face and skin folds, helps avoid side effects such as thinning of the skin.
Education and reference only. This is a plain-language guide to Clobetasone — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Clobetasone is a moderately potent topical corticosteroid (steroid) used in the UK to treat inflamed, itchy skin conditions such as eczema (dermatitis). It reduces the redness, swelling and itch of a flare, helping the skin to settle. It sits between mild and stronger steroids in strength, making it a useful step up from a mild steroid when that is not enough. It is applied to the skin in short courses to bring a flare under control, alongside regular moisturisers (emollients).
How it works
Clobetasone is a corticosteroid that calms inflammation in the skin. In conditions like eczema, the skin becomes inflamed, red and itchy; the steroid damps down the overactive immune and inflammatory response in the skin, reducing redness, swelling and itch so the skin can recover. Because it is absorbed into the skin where it is applied, using a thin layer in short courses gives the benefit while limiting effects such as skin thinning.

Practical use
How to take Clobetasone
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- Apply a thin layer to the affected skin only, using the 'fingertip unit' as a guide to how much to use.
- Use it in short courses to settle a flare, rather than continuously long term without review.
- Take extra care on the face and in skin folds (such as armpits and groin), where milder or shorter treatment is usually needed.
- Keep using your moisturisers (emollients) regularly, leaving a little time between the moisturiser and the steroid.
- Wash your hands after applying it, unless your hands are the area being treated.
- Stop and seek advice if the skin is not improving, looks infected, or you are needing it very often.
Weighing it up
Advantages & disadvantages of Clobetasone
Advantages
- It is effective at calming the redness, swelling and itch of an eczema flare.
- Its moderate strength is a useful step up when a mild steroid is not enough.
- Used as short courses with moisturisers, it brings flares under control quickly.
Disadvantages
- Prolonged or heavy use can thin the skin and cause other local effects.
- It needs extra care on the face and in skin folds, where the skin is thinner.
- It treats flares but does not cure eczema, so good moisturiser use and trigger avoidance are still needed.
Practical use
Good to know
Clobetasone is applied as a thin layer to the affected skin, using only enough to cover it — the 'fingertip unit' is a helpful guide for how much to use. It is meant for short courses to settle a flare, not for continuous long-term use without review, as prolonged or heavy use can thin the skin. Take extra care on delicate areas such as the face, and in skin folds (flexures) like the armpits and groin, where skin is thinner and absorbs more — these usually need milder treatment or shorter courses. Keep using your moisturisers (emollients) regularly alongside it, leaving a little time between applying them and the steroid. Wash your hands after applying it unless your hands are the area being treated.
Who should not take it / use with caution
- People with an untreated skin infection (bacterial, viral such as cold sores, or fungal) at the site, where a steroid alone could make it worse.
- Anyone who has had a serious allergic reaction to clobetasone or an ingredient in the cream or ointment.
- Used with particular caution on the face, in skin folds, and in young children, where milder treatment is usually preferred.
Monitoring
- Review of whether the flare is settling and whether the course can be stopped.
- Watching for signs of skin thinning or infection, especially with repeated use.
- Particular care when used on the face, in skin folds, or in children.
Side effects
- A burning or stinging feeling when first applied.
- With prolonged or heavy use, thinning of the skin, stretch marks, or visible small blood vessels.
- Worsening or spread of an untreated skin infection.
- Rarely, more widespread effects if very large amounts are used over large areas for a long time.
Key interactions
- It has few important interactions with medicines taken by mouth.
- Avoid applying other products to the same area at the same time unless advised; leave a gap between a moisturiser and the steroid.
- Tell your prescriber if you are using other creams or treatments on the same skin.
Available as: A cream and an ointment.
Answers
Clobetasone: frequently asked questions
How much clobetasone should I use?
Use only a thin layer, enough to cover the affected skin. The 'fingertip unit' — the amount squeezed onto the end of an adult fingertip — is a helpful guide to how much covers an area of skin. Using more than needed does not work better and raises the risk of side effects.
Can I use clobetasone on my face?
Use it on the face only with care and usually for short periods, as facial skin is thinner and absorbs more. A milder steroid is often preferred for the face, so follow your prescriber's advice and do not use it there long term without review.
Will clobetasone thin my skin?
Used correctly as a thin layer in short courses, the risk is low. However, prolonged or heavy use, especially on the face or in skin folds, can thin the skin. This is why it is used for short courses and reviewed rather than applied continuously without advice.
Should I still use my moisturiser?
Yes — keep using your moisturisers (emollients) regularly, as they are a key part of managing eczema. Leave a little time between applying a moisturiser and the steroid so each can work, rather than applying them at the exact same moment.
Why should I not use it on infected skin?
A steroid calms inflammation but can allow an infection to worsen or spread if used on its own on infected skin. If the skin looks infected — for example, weeping, crusted or rapidly worsening — seek advice, as a different or additional treatment may be needed.
