The author provides current statistical information on the incidence of rosacea and ambiguity surrounding the aetiology of the common, yet complex condition. The paper reinforces the importance of providing symptom specific treatments, as well as the key position of aesthetic nurses in improving the psychological and physiological wellbeing of affected patients in private practice, particularly in light of extensive NHS waiting lists. A detailed overview of the pathogenesis, and differential diagnoses is conveyed. The author draws attention to the absence of large cohort studies on rosacea and the subsequent inconsistencies in statistical reporting. The four subtypes of rosacea are described, (including the rare variant of granulomatous rosacea), supported by evidence from a current Cochrane review; topical, oral and light-based therapies are explored. Emphasis is placed on the frequent misdiagnosis on ocular rosacea, which is an important consideration for aesthetic nurses, as well as the differential diagnoses. Whilst the author acknowledges that acne and rosacea can coexist, it may have proved insightful for discussion on the diagnosis and management of a dual diagnosis. The author reinforces the importance of aesthetic nurses correctly interpreting current clinical guidelines as well as adopting a holistic approach to assessment and treatment. Concomitant treatment considerations are explored for patients receiving isotretinoin for rosacea, which is clinically relevant for nurses prescribing for rosacea in aesthetic practice. Given the prevalence of this condition, this is a useful, evidence-based article for the aesthetic nurse involved in the diagnosis and management of rosacea.
