Rosacea can be triggered by stress, too much alcohol or caffeine, spicy foods, intensive exercise or exposure to UV light. It tends to be more common in fair skinned people.
There are creams and gels available to apply to the affected area, such as azelaic acid. This should be applied once or twice a day and you should be prepared to wait several weeks before you see an improvement in your skin.
If your skin has become infected or inflamed, you may be prescribed antibiotics – for instance, erythromycin or tetracycline.
If your rosacea is particularly bad, your dermatology specialist may suggest a medicine that is usually used to treat acne, isotetinoin. However, this is a powerful medication and can cause side-effects such as joint pain, headaches and dry skin.
If you have a lot of facial flushing you may be given beta blockers. These slow the heart and reduce symptoms of anxiety.
