Rosacea or acne? How to tell the difference
Look for blackheads and whiteheads: they belong to acne, not rosacea. Rosacea bumps usually sit on a background of persistent central redness, often with flushing and stinging, and it usually starts in adulthood. The difference matters because some acne treatments irritate rosacea, and steroid creams can make it worse.

Why is rosacea mistaken for acne?
The bumps look alike. The British Association of Dermatologists describes rosacea’s small bumps and pus-filled spots as "similar to acne" (BAD leaflet, checked 18 October 2026), and the old name "acne rosacea" is still in use. Both conditions are common, both affect the face, and both improve with some of the same tablets. Yet they are different diseases with different triggers and different first-line creams.
Acne is marked by blackheads and whiteheads (comedones), alongside inflamed bumps, pus spots and sometimes deeper nodules (NHS, checked 18 October 2026). Rosacea centres on the facial blood vessels and the skin’s immune response. Its two diagnostic features are persistent central redness that intensifies from time to time and thickened skin; bumps and pustules are a major feature that appears on top of that redness.[1] Comedones do not appear in the consensus list of rosacea features.[2]
Rosacea vs acne: a side-by-side comparison
| Feature | Rosacea | Acne |
|---|---|---|
| Blackheads and whiteheads | Not part of rosacea | The defining lesion |
| Background skin | Persistent central redness that flares with triggers | Redness mainly around individual spots |
| Flushing, burning, stinging | Common; skincare often stings | Not a typical feature |
| Where | Cheeks, nose, chin, forehead | Face, chest and back |
| Usual age at onset | Adults; risk rises from 30 | Often starts around puberty |
| Eyes | Can be gritty, dry or red | Not involved |
| Thickened nose skin | Possible (rhinophyma) | No |
Age is a useful clue. The AAD lists being 30 or older among the risk factors for rosacea (AAD, checked 18 October 2026), and a meta-analysis found it most common between 45 and 60.[3] The NHS links acne to hormone changes, including those of puberty. New spots in your forties with a red background and no blackheads point towards rosacea.
Five questions that point to rosacea
- Are there no blackheads or whiteheads among the bumps?
- Does your face flush with heat, alcohol, spicy food or stress?
- Is the central face red even on days without spots?
- Do moisturisers or sunscreens often sting or burn?
- Do your eyes feel gritty or do your eyelids look red?
Several yes answers are a good reason to ask about rosacea, but only an examination confirms it. The types of rosacea guide explains the features a dermatologist looks for.
Can you have rosacea and acne at the same time?
Yes. Both are common, and the AAD lists a history of many acne breakouts, or a blood relative with severe acne, among the risk factors for rosacea. Someone who had acne as a teenager can develop rosacea in adulthood, and the two can overlap for a while. A dermatologist then treats each feature separately.
Why do the treatments differ?
Some medicines cross over, with different doses and plans. The NHS lists doxycycline and isotretinoin among acne tablets (NHS acne treatment, checked 18 October 2026). For rosacea, doxycycline comes as a 40 mg modified-release capsule labelled for rosacea bumps, and isotretinoin is used off-label at low dose: 0.25 mg/kg a day cleared at least 90% of lesions in 57.4% of patients in a placebo-controlled trial.[4] Azelaic acid also treats both.[5]
Others do not. The BAD advises people with rosacea to avoid some acne treatments, which can irritate rosacea-prone skin, and to avoid steroid creams unless a dermatologist recommends them. Brimonidine gel and oxymetazoline cream are labelled specifically for the persistent redness of rosacea. One exception shows that the formulation matters as much as the ingredient: the AAD’s list of rosacea treatments includes an encapsulated 5% benzoyl peroxide cream (AAD, checked 18 October 2026).
What if acne treatment made my face redder?
That pattern is a clue in itself. If a benzoyl peroxide wash, a retinoid or a strong acid left your face red, burning and still bumpy, rosacea may be the underlying problem rather than stubborn acne. Stop the irritating product, go back to a mild cleanser and moisturiser, and ask a dermatologist to see the skin. A steroid cream that seemed to help at first and then left the face redder is another reason to be checked, since the BAD notes that steroid creams may make rosacea worse.
What does a dermatologist check?
Diagnosis is made by examining the skin and eyes, and specific tests are not usually needed (BAD leaflet). Tests are added when another condition needs to be ruled out. Bring photos of flares, a list of every product you put on your face, and the names of any acne treatments that made your skin worse; that history helps settle the question.
If it is rosacea, see rosacea treatment options and the skincare guide for help choosing a gentle routine.
Is rosacea a type of acne?
No. Rosacea is a separate inflammatory condition centred on facial redness and blood vessels. The old name "acne rosacea" came from the acne-like bumps, and it still causes confusion.
Does rosacea cause blackheads?
No. Blackheads and whiteheads are the hallmark of acne and are not among the features of rosacea. If you have them, acne is present, with or without rosacea.[2]
Can acne face washes help rosacea?
Usually not. Strong acne washes and scrubs can sting rosacea skin. A mild, soap-free cleanser used with fingertips suits rosacea better.
