Rosacea is a common skin condition affecting the face, characterised by flushing, redness, pimples, pustules and dilated blood vessels. The eyes are often also involved. The cause of rosacea is unclear. It is a chronic disease, which can be controlled in most cases with appropriate treatment. Numerous treatments are in use although it is unclear which are best, and which are most appropriate for the different types of rosacea. ⋯ The quality of studies evaluating rosacea treatments was generally poor. There is evidence that topical metronidazole and azelaic acid cream have a therapeutic effect. There is some evidence that oral metronidazole and tetracycline are effective. There is insufficient evidence concerning the effectiveness of other treatments. As many of these treatments are used for rosacea, good RCTs are urgently needed.
