Current Rosacea Treatment Algorithms: Guide To Subtypes And Existing Therapies

By Marlis Sarkany

Rosacea is a common condition occurring on the convexities of the face and affecting middle-aged persons. It may be caused or worsened by a variety of different factors, including genetics; problems with the blood vessels in the face, the nervous system, and/or the immune system; the presence of Demodex mites; and environmental factors. It is a chronic condition that is not contagious.

Cases of rosacea are traditionally classified into three different subtypes. Each of these subtypes can also be broken down into smaller categories based on their severity, with grade 1 being the least severe and higher grades being more severe.¹ The recommended treatment for rosacea depends on the subtype and the grade of the individual’s condition, as well as on the phenotype, which will be presented separately.
