aetiology
Last reviewed 01/2018
- aetiology is unknown
- emotion, sun, hot drinks, alcohol and the incorrect use of topical corticosteroids
are important precipitating factors suggesting a lack of normal homeostatic
control of the blood vessels supplying the pilosebaceous follicle
- the mite Demodex folliculorum can be found on the face in large numbers but this association is speculative. Similarly rosacea has been anecdotally associated with seborrhoeic dermatitis, and in women with migraine headaches (1)
