- UK tubes and boxes now show one of four strengths: "mild", "moderate", "strong" or "very strong". Hydrocortisone is mild, clobetasone moderate, betamethasone strong and clobetasol very strong (Pharmaceutical Journal, June 2024). The US uses seven classes, I to VII, with class I the most potent (Sandoval et al. 2013).
- In a 2021 umbrella review of 38 systematic reviews, short trials of topical steroids showed no significant difference in skin thinning compared with emollient, with very low event rates. Skin thinning was rare overall, at 8 of 2,068 people (0.4%) treated with steroids, and 7 of those 8 cases involved potent products (Axon et al. 2021).
- Skin thinning and striae are most linked to potent products, large areas, occlusion, thin skin such as the face and groin, and long continuous use (Stacey & McEleney, American Family Physician 2021). Striae were not studied in the trials we reviewed.
- Withdrawal-type reactions are the contested part. The MHRA received 267 Yellow Card reports between September 2021 and August 2023. Most described severe reactions after at least six months of moderate-to-very-potent steroids for eczema (Pharmaceutical Journal). The evidence base for a distinct syndrome is weak, and the Feb 2024 joint statement from Eczema UK, the British Association of Dermatologists and the British Dermatological Nursing Group covers the withdrawal debate (Eczema UK).
- Money trail: the two most rigorous safety reviews we opened were publicly funded by the UK's National Institute for Health and Care Research (NIHR). The authors of one of them declare ties to AbbVie and Eli Lilly, neither of which the review names as a topical steroid maker (Harvey et al. 2023). We did not identify the funders of the older trials of topical steroids themselves, so the manufacturer-funded part of the evidence remains unverified.
- Proper use, per clinical guidance: the AAFP suggests treating the face, groin and skin folds in short one-to-two-week blocks, and limits super-high-potency products to about three weeks at a time and high or medium products to about 12 weeks (AAFP 2021).
- Confidence: Moderate that potent steroids on thin skin and long continuous use carry the main atrophy risk. Insufficient for striae. Weak for the existence and frequency of a withdrawal syndrome.
Independent evidence review · Prescription medicine
Topical corticosteroids remain a standard way to treat inflammatory skin disease when the strength, site and duration match the problem. The best independent evidence says short, appropriate courses rarely cause measurable skin thinning, while potent products on the face, groin and skin folds, and long continuous use, carry the main risk. Whether a separate "topical steroid withdrawal" syndrome exists is much less settled. The evidence is weak, and UK regulators and professional bodies describe it as poorly understood. Our confidence is moderate on the atrophy risk factors and low on the withdrawal syndrome.

Independent evidence and credibility scorecard
Independence tiers: 1 = independent, with no identifiable financial stake in the outcome; 2 = indirect ties, such as grant interests or declared sponsorship from a company in a neighbouring field; 3 = interested party, such as a patient charity or advocacy body; 4 = self-interested, meaning funded, sponsored or written by the maker or seller. Credibility runs from A (highest) to D. Every row below is a source we opened. Where a funding statement was not visible, we say so.

Convergence and clustering. Two sources with no declared financial ties (Stacey and Sheary) agree with the two NIHR-funded reviews on the main risk factors: potency, duration, the face and genitals, and occlusion. The regulator and the patient charity also agree that severe reactions reported to the MHRA followed long-term use of moderate-to-potent steroids. Their incentives differ, which makes that agreement more useful. Five of the eight sources are UK-based, two are US-based and one is Australian. The verdict on withdrawal therefore reflects a UK lens, and no manufacturer-funded source was among those we could open.
What topical steroids are, and how strength is labelled
Topical corticosteroids are creams, ointments, lotions and foams that reduce skin inflammation. Clinicians use them most often for eczema and plaque psoriasis. The American Family Physician overview groups them into four bands: super-high (class I), high (class II), medium (classes III to V) and low (classes VI and VII). Super-high products are reserved for severe disease and thick skin, such as the palms, soles and psoriatic plaques. Low-potency products suit children, mild or widespread disease, and thin skin such as the face and groin (Stacey & McEleney 2021).
Potency classes in the UK
Since the MHRA's May 2024 statement, UK packs must show one of four strength words: "mild", "moderate", "strong" or "very strong". The Pharmaceutical Journal gives the examples hydrocortisone (mild), clobetasone (moderate), betamethasone (strong) and clobetasol (very strong). The Pharmaceutical Journal says the new labels would be introduced over the next year (Pharmaceutical Journal 2024). We could not open the BNF potency table, so the BNF's own grouping is not confirmed here.
Potency classes in the US
The US uses seven classes, from class 1 (the most potent) to class 7 (the least). Potency is based on vasoconstrictor assays, which measure how strongly a steroid narrows skin blood vessels, and is used as a proxy for activity on the skin (Sandoval et al. 2013). Because the US and UK schemes are built differently, do not map one onto the other. We could not open a product-level US table, so we do not list the US class of individual products.
How they work
Topical steroids reduce the local inflammation that drives eczema and psoriasis. The US classes are based on vasoconstrictor assays, which measure one effect of the steroid on skin blood vessels (Sandoval 2013). That is a measure of strength, not a direct measure of every effect on skin thickness. What is proven: the local anti-inflammatory effect is the reason clinicians use these drugs, and the skin-thinning risk is measured in trials. What is not proven: the exact cellular route by which thin skin and withdrawal-type reactions occur. We did not open a primary mechanism study, so we do not describe one.
What works and what does not
| Approach | What the evidence shows | Verdict |
|---|---|---|
| Short courses at the strength matched to the site | Clinical guidance treats face, groin and skin folds in one-to-two-week blocks (AAFP 2021). | Works (guidance) |
| Intermittent or proactive twice-weekly use after flares | No skin thinning in five trials, n=993, 16–20 weeks (Axon 2021). Long-term data are limited. | Mixed |
| Continuous potent or very potent use on the face, groin or skin folds | Highest risk of thinning, striae and withdrawal flares (AAFP 2021; Sheary 2016). | Avoid unless a clinician directs |
| Preventing striae | Not studied in the trials we opened (Axon 2021; Harvey 2023). | Insufficient |
| Treating a "withdrawal" reaction with a fixed steroid-stopping plan | No controlled trial we opened tests it. | Insufficient |
Benefits by claim
Do topical steroids treat eczema flares?
They are the standard anti-inflammatory treatment for flares, and the clinical guidance we opened is written around that use. This article is a safety and withdrawal review, so we do not rate their efficacy against other treatments. For that question, see the related guides below.
Can they treat psoriasis plaques?
The AAFP limits super-high-potency products to no more than three weeks at a time (AAFP 2021).
Risks and all side effects
Skin thinning (atrophy)
Skin thinning is the best-documented local risk. In trials of two to four weeks, we found no meaningful difference between steroid and emollient. Against calcineurin inhibitors, the pooled relative risk was 4.86, with a wide confidence interval (1.06 to 22.28). The absolute rate was 0.4%, with seven of eight cases from potent products. Most of the systematic reviews it included were rated low or critically low quality, and most trials lasted only 2–4 weeks, so long-term thinning is not well measured (Axon et al. 2021).
Striae (stretch marks)
Clinical guidance lists striae among the most common adverse effects of topical steroids, alongside atrophy (AAFP 2021). The trials did not report striae. The two wet-wrap observational studies in the umbrella review reported one case (Axon 2021). We could not verify whether striae reverse after stopping, so we do not state a reversibility rate.
Rebound and "withdrawal" reactions
The AAFP reports that stopping prolonged use on the face or genitals can cause redness, scaling, stinging, burning, papules, pustules and oedema. It also says there is no evidence of tachyphylaxis, meaning the steroid does not stop working with use (AAFP 2021). The separate claim of a "topical steroid withdrawal" syndrome rests on weaker evidence. A 2015 systematic review (Hajar et al., summarised by Sheary 2016) describes the syndrome as occurring mainly after long-term use of moderate-to-high-potency steroids, particularly on the face or genitals. Sheary calls the evidence limited. The 2023 review found no data on withdrawal at all (Harvey et al. 2023). The full text of the 2024 joint statement was not reopened in this check (Eczema UK 2024).
Systemic effects
Clinical guidance says the risk of systemic adverse effects in adults is low if doses do not exceed 50 g per week (AAFP 2021). The 2023 review found a small association with type 2 diabetes (odds ratio 1.27, 95% CI 1.19 to 1.36) in one case-control study, rated as very low certainty. Lymphoma findings conflicted (Harvey et al. 2023).
All interactions
We did not open an interactions database. The main interaction we can source is additive systemic exposure: the AAFP's systemic-risk discussion depends on total dose, so steroid tablets, injections or high-dose inhaled steroids used alongside a cream add to that total. Tell your prescriber about every steroid you use (AAFP 2021). We could not verify interaction data for other drugs.
Who should take extra care
- Children: in the PETITE trial, the one case of skin thinning among 1,213 children occurred on mild or moderate steroids (Axon 2021). Ask the prescriber for the plan for your child.
- Thin skin and skin folds: the face, groin and skin folds absorb more, so the AAFP limits strength and duration there.
- Pregnancy and breastfeeding: we did not open a source for this group, so we do not give a risk estimate. Ask a clinician.
- People on other steroids: the cumulative dose matters (see Interactions).
Doses studied and proper use
The figures below are guidance from the AAFP and the approaches studied in trials. They are not personal instructions. A prescriber should set the plan for each person.
- Duration: super-high products up to about three weeks at a time; high and medium products up to about 12 weeks, with longer courses using intermittent dosing or a milder product.
- Face, groin and skin folds: one-to-two-week intervals (same source).
- Trial approaches: weekend or proactive twice-weekly dosing has been studied in trials, and the umbrella review found no skin thinning in those trials, although they were short (Axon 2021).
Product quality and labelling
The MHRA's labels aim to make strength clear on the pack, tube and leaflet (Eczema UK 2025). We found no product-quality or contamination issues for topical steroids in the sources we opened.
Follow the money: who makes it and who funded the evidence
Who makes and sells it
We could not verify the manufacturers, parent companies or ownership of the main UK, US or European steroid brands from an opened source, so we name none. Readers who want this should check the manufacturer and regulator entries directly.
Who funded the evidence
- Axon et al. 2021 (umbrella review): NIHR Programme Grants for Applied Research, grant RP-PG-0216-20007. The authors state that the NIHR, the NHS and the Department of Health and Social Care did not necessarily share their views. The authors are co-applicants on the grant, which funds an eczema self-care project (BMJ Open 2021).
- Harvey et al. 2023: NIHR Programme Grants, grant RP-PG-0216-20007. The funders had no role in the study. Alison Lowe has worked for AbbVie and taken sponsorship from AbbVie and Eli Lilly for events. Sandra Lawton received an honorarium and took part in an AbbVie-funded podcast (Harvey et al. 2023).
- Stacey & McEleney 2021: no separate funding statement; authors declare no relevant financial affiliations (AAFP 2021).
- Sheary 2016: no funding; competing interests "None" (Sheary 2016).
- Sandoval et al. 2013: the funding and conflict statement was not in the part we opened (Sandoval 2013).
- Manufacturer-funded trials of topical steroids: we did not find a documented manufacturer-funded trial of topical steroid skin thinning among the sources we opened. The older trials in the umbrella review were not opened individually, so this remains unverified.
Patient groups and their positions
- Eczema UK, BAD and the British Dermatological Nursing Group (22 Feb 2024): the date and co-authors come from search results and the statement's PDF header. The PDF text was not readable in this check, so its wording and any funding statement are not quoted or verified (Eczema UK 2024).
- Eczema UK's labelling campaign: the charity's news listing reports a 2023 campaign for clear strength labels and a 9 July 2025 article announcing the labels. Its survey figures were not reopened in this check (Eczema UK 2025). This is a charity's own account of its campaign.
Documented integrity events
We found no documented regulatory warning letter, recall or prosecution specific to topical steroid makers in the sources we opened. The MHRA's 2024 Yellow Card analysis is the main documented safety event (Pharmaceutical Journal 2024).
Research funding at a glance
8 sources graded. The counts below are the independence tiers assigned in the scorecard above. They count sources, not funding amounts or evidence quality.
Public funding alone does not prove independence, and commercial funding alone does not prove a claim false. Named funders, countries and relationships are in the scorecard and source notes.
What this means: the strongest safety evidence we opened is publicly funded, and the regulator has no product to sell. The Tier 4 count of zero reflects the sources we could open, not an absence of manufacturer-funded trials. That gap is important, because the trial-based safety data in the umbrella review came from older studies whose funders we could not check.

Frequently asked questions
What do the UK strength labels mean?
Products are now labelled "mild", "moderate", "strong" or "very strong". Hydrocortisone is mild, clobetasone moderate, betamethasone strong and clobetasol very strong (Pharmaceutical Journal 2024).
Do topical steroids thin the skin?
Short and intermittent use showed no measurable thinning in the trials we opened. Potent products carried most of the risk in the rare cases reported. The pooled absolute rate was 0.4% in steroid-treated people, with no cases in comparators (Axon et al. 2021).
Can topical steroids cause stretch marks?
Clinical guidance lists striae as a common local effect (AAFP 2021). The trials did not report striae, so we cannot give a reliable rate.
What is topical steroid withdrawal?
It is a term for skin symptoms that some people describe after stopping long-term steroids. The MHRA describes severe reactions after at least six months of moderate-to-very-potent steroids for eczema (Pharmaceutical Journal 2024). The syndrome is described mainly on the face or genitals after potent use, and the evidence is weak (Sheary 2016; Eczema UK 2024).
Has the MHRA or the NHS recognised topical steroid withdrawal?
The MHRA published its Yellow Card analysis in May 2024, reporting 267 reports between September 2021 and August 2023 (Pharmaceutical Journal 2024). We could not open an NHS-issued statement on the condition, so we cannot confirm one.
Are topical steroids safe for children?
In the PETITE trial, one case of skin thinning occurred among 1,213 children, all on mild or moderate steroids (Axon et al. 2021). Ask the prescriber for the plan for your child.
Should someone stop a steroid cream if they are worried about it?
Do not stop a prescribed steroid suddenly without advice. Speak to your GP, pharmacist or prescriber first, as the safety box above says.
Who pays for the research on topical steroids?
The two most rigorous safety reviews we opened were funded by the UK's NIHR. One set of authors declares ties to AbbVie and Eli Lilly, neither named as a topical steroid maker (Harvey et al. 2023). We could not verify the funders of the older trials of topical steroids.
Sources and funding notes
What we could not verify or open: the BNF topical corticosteroid entry and the NICE appendix returned access errors in an earlier check and were not retried. PubMed returned a rate-limit error, so the 2015 Hajar systematic review and the 2015 Barnes review of skin atrophy are cited only as summarised by other sources and are not counted in the scorecard. The Eczema UK, BAD and BDNG joint statement PDF could not be read in this check, so its wording and funding are not verified. We did not find a separate 2023 MHRA or NHS England statement on withdrawal. We could not verify the funding of Eczema UK, the BAD or the AAFP. We found no documented manufacturer-funded steroid trial in the sources we opened, and we could not check the funders of the older trials. We did not verify manufacturer names or ownership. Search limits also stopped one planned check of NICE CKS guidance on proper use, so the proper-use section relies on the AAFP overview. Checked in this later pass: the BMJ Open umbrella review (Axon et al. 2021, via PMC) and the MHRA Drug Safety Update of 29 May 2024 were opened. The Axon figures (RR 4.86, 95% CI 1.06 to 22.28; 8 of 2,068 steroid cases vs 0 of 2,060; five twice-weekly trials, n=993) match the source. The MHRA figure (267 reports, up to August 2023) matches the Drug Safety Update, which gives no start date; the September 2021 start comes from the Pharmaceutical Journal. Harvey et al. 2023 (via PMC) matches on funding, the AbbVie and Eli Lilly ties, the type 2 diabetes odds ratio and the lack of withdrawal data. Two discrepancies remain noted here: the Axon grant is written RP-PG-0216-20007 in the funding statement and P-PG-0216-20007 in the competing-interests section, and the PETITE count is 1,213 in one section and 2,418 in another. The Eczema UK labelling article is dated 9 July 2025 and carries no funding statement; the 2023 survey article (943 responses) is not used.
