If you have eczema, topical steroid creams are often a key part of your treatment plan, yet they’re also one of the most misunderstood. Many people worry about side effects or avoid using them altogether, which can actually make eczema harder to control.
The good news is that when used correctly, topical steroids are safe, effective, and recommended by UK dermatology guidance. Understanding how, and when, to use them can make a big difference to your skin and your confidence in treatment. Read on as Dr Rina, Winchester GP with special interest in dermatology helps you to get the best out of steroid treatments.
Why Steroid Creams Are Used for Eczema
Eczema is an inflammatory skin condition, not just dry skin. During a flare, the immune system in the skin becomes overactive, leading to redness, itching, soreness and damage to the skin barrier.
Topical corticosteroids work by:
Reducing inflammation
Relieving itching
Helping the skin barrier recover
Preventing flares from worsening or becoming infected
Moisturisers are essential, but they cannot treat inflammation on their own — this is where steroid creams play an important role.
Understanding Steroid Strengths (Potency)
Topical steroids come in different strengths, and choosing the right one depends on where the eczema is, how severe it is, and who it’s being used for.
In general:
Mild steroids are used on delicate areas such as the face, neck and skin folds
Moderate steroids are often used on thetrunk and limbs
Potent steroids may be needed for thicker skin, such as the hands or feet
Very potent steroids are usually reserved for short-term use under specialist supervision
Using the right strength in the right place is key to both effectiveness and safety.
How to Use Steroid Creams Correctly During a Flare
Start Early
Steroid creams work best when used at the first sign of a flare — when the skin becomes red, itchy or inflamed. Delaying treatment often means symptoms become more severe and harder to settle.
Apply Once Daily Unless Advised Otherwise
Most steroid creams are effective when applied once daily. Applying more often does not usually improve results and may increase the risk of side effects.
Always follow the instructions given by your GP or dermatologist.
Use the Right Amount
Steroids should be applied in a thin, even layerto areas of active eczema only.
Healthcare professionals often use the fingertip unit (FTU) as a guide:
One fingertip of cream covers roughly two adult handprints of skin
Using too little is a very common reason treatment doesn’t work as expected.
Continue for the Prescribed Course
A common mistake is stopping treatment as soon as the skin looks “better”.
UK guidance typically recommends using topical steroids for a defined course, often 7–14 days, depending on severity and location. Treatment should usually continue until inflammation has fully settled — not just until it starts to improve.
Always follow the course advised by your clinician rather than stopping early.
How Steroids and Moisturisers Work Together
Steroid creams and emollients are not alternatives — they work best as a team.
Use emollients generously every day, even when eczema is under control
Apply steroid cream to inflamed areas
If possible, leave a short gap (around 20–30 minutes) between applying steroid and moisturiser
Emollients should be continued long-term to protect the skin barrier and reduce future flares.
What If You Have Frequent Flare-Ups?
For people who experience repeated flares in the same areas, UK dermatology guidance supports a maintenance or “weekend therapy” approach.
This involves applying a steroid (or a non-steroid anti-inflammatory alternative) to previously affected areas on two consecutive days each week, even when the skin looks clear.
This strategy has been shown to:
Reduce the frequency of flares
Improve long-term eczema control
Reduce the need for repeated full treatment courses
Your GP can advise whether this approach is appropriate for you.
Are Steroid Creams Safe?
When used as prescribed, topical steroids are considered safe and effective.
Side effects such as skin thinning are uncommon and are usually associated with:
Using a steroid that is too strong for the area
Prolonged continuous use without breaks
Incorrect application
Importantly, poorly controlled eczema carries its own risks, including broken skin, infection, sleep disturbance and reduced quality of life.
What About Topical Steroid Withdrawal?
You may have heard about topical steroid withdrawal (TSW). UK professional bodies acknowledge that withdrawal reactions have been reported, but they are considered uncommon and most often associated with long-term, inappropriate use of potent steroids.
If you are unsure about any element of your eczema management, it’s important book in an appointment with a GP or dermatologist. Key considerations will be
Whether you are using the correct potency of steroid,
How long you are using them for
Whether your symptoms are appropriate controlled by the treatment and how quickly they return after treatment.
Any side effects you might be experiencing
It’s also important to keep an eye out for any infection (weeping, crusting, pain) as eczematous skin is particularly vulnerable
