An introduction to treating rosacea
Abstract
Rosacea is a fairly common condition, especially in fair-haired, blue-eyed people, that mainly affects the centre of the face, causing erythema and papules and pustules. It is a chronic condition and requires correct diagnosis and careful management to achieve optimal results. Gentle skincare is vital. Topical agents, such as azelaic acid, metronidazole, ivermectin and brimodinine tartrate are useful. Oral antibiotics, such as doxcycline and clarithromycin, as well as isotretinion, also play a role. Aesthetic clinics may see patients presenting for laser or intense pulsed light treatments for the telangectasia that is often present. This forms only part of the overall package of treatments.
Rosacea is a common chronic skin condition that affects the face. It is most common in fair-haired, blue-eyed people, and affects approximately 5% of the world's population (Gether et al, 2018). There is a bimodal prevalence, with the main peak occurring between the ages of 40–50 years.

Diagnosis can still be difficult, and conditions can co-exist. Sometimes a biopsy is necessary for diagnosis.
In 2017, Tan et al endorsed a consensus of diagnostic criteria, constructed by a panel of international experts from ROSacea COnsensus (ROSCO). It is considered to be a useful diagnostic schema.
