Why Is My Face Red? Common Causes of Facial Redness

A red face usually comes from one of a few causes: flushing or blushing from heat, exercise, alcohol or emotion; irritation from a harsh cleanser or too much exfoliating; sunburn; rosacea, which brings recurring redness across the nose and cheeks; seborrheic dermatitis, which adds flaky patches around the nose and brows; or a reaction to something touching your skin. The pattern and timing usually point to which one.

Below is a cause finder you can work through in a few minutes, a table that compares the usual suspects side by side, the signs that mean you should see a doctor soon, and what you can do today to calm things down without making them worse.

What are the most common causes of a red face?

Most facial redness falls into two groups: short-lived redness that comes and goes with a trigger, and redness that lingers for days or keeps coming back. Flushing, blushing and a reaction to hot food belong to the first group. Irritation, allergy, sunburn, rosacea and seborrheic dermatitis belong to the second. Start by asking three questions: how long does the redness last, where exactly is it, and what else do you feel (stinging, itching, flaking, bumps)?

Redness can be harder to see on brown and black skin. On deeper skin tones, the same problems may look brown, purple, gray or darker than the surrounding skin, so pay more attention to warmth, stinging and texture than to color alone.

Why is my face red after washing?

A face that turns red right after washing is most often reacting to the cleanser, the water temperature or the way you wash. The NHS says contact dermatitis is most commonly caused by irritants such as soaps and detergents, solvents or regular contact with water. A foaming cleanser that leaves your skin squeaky, hot water and a rough washcloth can all add up.

If redness fades soon after you dry off and your skin feels fine afterward, it's probably just warmth and friction. If it stings, feels tight or lasts for hours, try a gentler routine for two weeks:

• Switch to a mild, fragrance-free cleanser and wash with your fingertips.
• Use lukewarm water instead of hot.
• Pat dry; don't rub.
• Moisturize straight away.

Stinging from plain water deserves attention. The American Academy of Dermatology (AAD) lists burning or stinging when you apply anything to your face, even water, as one of the symptoms of rosacea. If your skin reacts to almost everything, our guide to a damaged skin barrier explains how to rebuild tolerance.

Can over-exfoliating make your face red?

Yes. Scrubs, acid toners, peel pads, retinoids and cleansing brushes all remove or loosen the outer layer of skin, and stacking them is a common reason for a red, shiny, tender face. The AAD warns that exfoliating should be done safely so it does not lead to increased redness or acne breakouts, and that over-exfoliating can leave skin red and irritated. The same page notes that dry, sensitive or acne-prone skin may find mechanical exfoliation too irritating, and that the more aggressive the method, the less often it should be used.

The fix is boring but works: stop every exfoliant and active for one to two weeks, keep to cleanser, moisturizer and sunscreen, and then bring back one product at a time, no more than a couple of times a week.

What's the difference between flushing and blushing?

Blushing is flushing triggered by emotion; flushing is the broader term for redness that appears when blood vessels in the skin widen. DermNet describes simple blushing as flushing due to embarrassment or anxiety, and lists many other causes: hot drinks, hot or spicy food, alcohol and certain medicines among them.

• Food and drink: DermNet notes that hot beverages, hot food or spicy food may cause flushing in otherwise healthy people, and that sulfites in wine and beer or nitrites in cured meats can do it in some people.
• Alcohol: some people, particularly of East Asian ancestry, flush after small amounts because of a less active enzyme that leads to a build-up of acetaldehyde.
• Medicines: the DermNet list includes calcium channel blockers and nicotinic acid (niacin), among others. Never stop a prescribed medicine on your own; ask the prescriber.

Occasional flushing that settles within minutes is normal. Flushing that happens more easily than it used to, lasts longer each time, or leaves redness behind is worth a closer look, because that pattern is how rosacea often starts.

Is redness on my cheeks and nose rosacea?

It might be, if the redness sits in the center of your face and keeps returning. The AAD says rosacea usually develops across the nose and cheeks and often begins with a tendency to flush easily. Over time the color may last for weeks or months, small blood vessels may become visible on lighter skin, and many people get acne-like bumps. On darker skin, the AAD notes the only sign of flushing may be a warm feeling on the cheeks.

The NHS says rosacea is more common in women and people with lighter skin, though symptoms can be worse in men, and lists common triggers such as alcohol, spicy food, hot drinks, sunlight, temperature changes, aerobic exercise and stress. It also says rosacea can look a lot like acne, contact dermatitis, seborrheic dermatitis, lupus and keratosis pilaris, which is why a diagnosis needs a clinician.

If you suspect rosacea, read our guides on how to tell rosacea from acne and rosacea triggers and how to track your own. A dermatologist can confirm it and offer treatment, which the AAD says can keep it from getting worse.

Could it be seborrheic dermatitis?

If the redness comes with flakes around your nose, in your eyebrows or along the hairline, seborrheic dermatitis is a likely suspect. The AAD describes it as a common condition that causes a scaly rash on oily areas like the scalp and face, including the ears, eyebrows, beard and skin around the nostrils. The scale is white to yellowish and can be dry or greasy. On darker skin the rash often looks pink, slightly purple or lighter than the surrounding skin.

The AAD notes that flare-ups are often seasonal, mostly in winter and early spring, and many people flare when stressed. Dandruff is considered its mildest form, so a flaky scalp alongside flaky brows is a useful clue. See our guide to flaky skin around the nose and eyebrows for more.

Is it sunburn?

Redness that appeared after time outdoors, feels hot and sore, and sits on the high points of your face is most likely sunburn. The NHS says sunburn usually gets better within 7 days, often flakes or peels a few days later, and may not show as a color change on black or brown skin.

For care, the NHS suggests getting out of the sun, cooling your skin with a cool shower or damp towel, using aftersun or an unperfumed moisturizer, drinking plenty of water, and taking painkillers following the leaflet. It also says not to use petroleum jelly on sunburnt skin, not to put ice on it, and not to pop blisters. For a full plan, see sunburn on your face: what to do in the first 48 hours.

Could I be allergic to a skincare product?

Possibly, especially if the redness itches and showed up a day or two after you started something new. The NHS explains that contact dermatitis can be caused by an irritant or an allergen, and that allergic contact dermatitis is less common and can be triggered by substances in products such as cosmetics, or metals like nickel. The reaction usually appears within a few hours or days of exposure, and the skin may become itchy, blistered, dry and cracked. Lighter skin turns red; darker skin may turn dark brown, purple or gray.

Stop the most recent product first. The NHS says the skin usually clears once the irritant or allergen is identified and avoided, and that a GP can refer you for tests if the cause can't be found.

When should I see a doctor about a red face?

See a doctor promptly if redness comes with any of these red flags:

• Eye symptoms with facial redness: the NHS advises an urgent appointment if you have rosacea and a painful eye, blurred vision, sensitivity to light, a red eye or a gritty feeling, which can be signs of keratitis.
• Sudden swelling: swelling of the lips, tongue or throat, or trouble breathing or swallowing, is an emergency. The NHS page on angioedema says to call emergency services in that situation; in the US, call 911.
• Bad sunburn: the NHS lists blistered or swollen skin, a very high temperature or feeling hot, cold or shivery, feeling very tired, dizzy or sick, a headache, or muscle cramps as reasons to get urgent help.
• Flushing with other symptoms: DermNet notes some flushing conditions come with low blood pressure, fainting and breathing difficulties.
• A rash across the nose and cheeks with joint pain or tiredness, which needs a doctor to rule out conditions like lupus, one of the look-alikes the NHS lists for rosacea.
• Redness that keeps coming back or has become permanent, spreads, blisters or doesn't improve after two weeks of a gentle routine.

Ask a clinician before putting hydrocortisone or another steroid cream on facial redness. DermNet advises people with rosacea to avoid topical steroids, as they may aggravate the condition, so the cause matters.

How can I calm a red face today?

Whatever the cause, these steps are low risk while you work out what's going on:

1. Cool down: step out of the heat, take off a layer, sip a cold drink.
2. Pause every exfoliant, retinoid, acid and new product.
3. Wash once or twice a day with lukewarm water and a mild, fragrance-free cleanser.
4. Use a plain, fragrance-free moisturizer.
5. Wear a fragrance-free, broad-spectrum sunscreen of at least SPF 30 when you go out.
6. Write down what happened in the hours before the redness started.

How can a selfie scan help you track redness?

Redness changes from hour to hour, which makes it hard to judge by memory. A dated photo record taken in the same light makes patterns easier to see, and it's useful to show a dermatologist. Pori takes a selfie and returns an overall skin score with a breakdown that includes Pigmentation & Tone and Overall health, and its before/after comparison lets you put two days side by side. Its skin diary logs sleep, water, stress and diet, which helps when you're trying to link a flare to a late night or a particular meal.

An app can't tell you whether your redness is rosacea, dermatitis or something else. Pori is not a medical device and doesn't diagnose, so use it to keep track and let a dermatologist make the call.
