Facial redness and flushing
Facial flushing is a normal response of the blood vessels of the face to heat, emotion or exertion. It becomes a reason to seek advice when it happens frequently, without an apparent cause, or when the redness becomes permanent. Behind it there may be anything from rosacea to a hormonal change, and in a few cases a cause worth not overlooking.
When it is normal
- with heat, physical exertion or sudden temperature change;
- with strong emotion: embarrassment, anger, nervousness;
- after spicy food, alcohol or very hot drinks;
- it lasts minutes and clears completely with no trace.
Common causes
- rosacea: the commonest cause of persistent redness. Over time visible vessels and sometimes papules appear;
- menopause and perimenopause: hot flushes with heat rising from the chest, sweating and palpitations, particularly at night;
- medicines: nicotinic acid, some blood pressure drugs such as calcium channel blockers, nitrates, tamoxifen, corticosteroids, sildenafil;
- alcohol, particularly in people with a deficiency of the enzyme that metabolises it, common in people of East Asian descent;
- foods: spice, monosodium glutamate, sulphites, mature cheeses;
- anxiety and fear of blushing: the fear itself triggers the flush and closes the loop;
- fever and infections;
- hyperthyroidism;
- seborrhoeic and contact dermatitis;
- lupus: a butterfly rash that spares the nasolabial folds and comes with other symptoms;
- chronic sun damage with permanently dilated vessels.
Uncommon causes worth excluding
These are rare, but they are the reason an atypical flush deserves investigation:
- carcinoid syndrome: intense flushing with diarrhoea, wheezing and palpitations;
- phaeochromocytoma: episodes of high blood pressure with sweating, pallor or flushing, headache and palpitations;
- mastocytosis: flushing with itching, weals and sometimes episodes of low blood pressure;
- neuroendocrine tumours and medullary thyroid carcinoma.
When to see a doctor
- the redness has become permanent or visible vessels have appeared;
- episodes are frequent and you cannot identify a trigger;
- they come with diarrhoea, abdominal pain or weight loss;
- there are palpitations, severe headache or blood pressure surges during episodes;
- wheezing or breathlessness occurs;
- there is generalised itching or weals;
- the flushing occurs at night and wakes you;
- it started after beginning a new medicine;
- there are skin lesions as well as the redness;
- it limits you socially or at work — reason enough to attend.
Urgent care if flushing comes with swelling of the lips or tongue, difficulty breathing, dizziness or loss of consciousness: this may be an anaphylactic reaction.
How it is investigated
The history comes first: what triggers the episodes, how long they last, what accompanies them and what medicines you take. A two-week diary recording time, food, drink, medication and situation is the most useful tool.
Depending on the case: thyroid function, full blood count, liver and kidney function and, if the pattern suggests it, specific tests for carcinoid, phaeochromocytoma or mastocytosis. In most people that level of investigation is never needed.
What you can do
- identify and avoid your personal triggers: alcohol, spice, hot drinks, heat;
- daily sun protection: sun damages the vessels cumulatively;
- gentle facial care, without scrubs, alcohol or fragrance;
- lukewarm rather than hot water, and avoid saunas and very hot baths;
- dress in layers and keep the bedroom cool if you have night flushes;
- breathing and relaxation techniques if anxiety is the trigger;
- green-tinted make-up to neutralise redness, if you wish;
- do not use steroid creams on the face: they improve things for a few days and then make redness considerably worse.
Treatment
- treat the cause: this is what resolves the problem;
- rosacea: topical metronidazole, azelaic acid or ivermectin, oral doxycycline;
- topical brimonidine to reduce redness temporarily;
- vascular laser or intense pulsed light: the only thing that acts on already dilated vessels;
- hormone therapy or non-hormonal alternatives for menopausal flushes;
- beta blockers for anxiety-related blushing in specific situations;
- cognitive behavioural therapy for fear of blushing;
- changing the responsible medicine, always on medical advice.
Common questions
Is it rosacea? It is the commonest cause when redness becomes persistent, but it needs confirming.
Can visible vessels be removed? Yes, with vascular laser or intense pulsed light over several sessions.
Do menopausal flushes last forever? No, although they can last years. Effective treatment exists.
Can I drink alcohol? If it is a clear trigger for you, cutting it back changes a great deal.
Is blushing dangerous? In itself, no. What gets investigated is the cause when the pattern is unusual.
Online consultation
In an online consultation the doctor analyses the pattern of your episodes and what accompanies them, reviews your medication, distinguishes rosacea from a hormonal flush and from less common causes, advises which tests are worthwhile and suggests concrete measures to reduce the episodes.
