Rosacea
A common long-term skin condition that mainly affects the face, causing redness, flushing, visible blood vessels, and sometimes small bumps. It tends to flare and settle and is more common in fair-skinned adults.
⚠ Seek medical attention if:
Eye irritation, grittiness, or vision changes (ocular rosacea), or significant skin thickening, need medical assessment. A sudden severe facial rash with swelling or pain should also be checked. See a GP for these.
Lifestyle factors
Sun exposure, hot drinks, spicy foods, alcohol, stress, extremes of temperature, and some skincare products can trigger flares
Nutritional factors
Common dietary triggers include alcohol, spicy foods, and hot drinks; some people notice a link with gut health, though the evidence is limited
Possible medical causes
The exact cause is unknown but involves blood vessel and immune factors; a skin mite (Demodex) and genetics may play a role
Next steps
See a GP or dermatologist, as rosacea can be managed with prescription treatments and by avoiding triggers. It cannot be cured but can be well controlled.
