What causes rosacea?
Although research continues into the skin complaint, an exact cause is not known, there are a number of theories & common factors that often present in rosacea suffers, although none of these factors have definitely been proven.
- Very small blood vessels under the troubled skin may become abnormal or leaky.
- Sun damage.
- A tiny mite called demodex folliculorum may be involved. It lives harmlessly on the skin of many people but has been found in higher numbers in those with rosacea.
- Abnormal immune system reactions in the skin, which lead to inflammation.
- Genetics may also be involved as rosacea may run in some families.
