Rosacea is a chronic inflammatory skin condition affecting primarily the cheeks, nose, chin, and forehead. It results in erythema (redness), flushing, telangiectasia (spider veins), and inflamed bumps. Rosacea can also affect the eyes (ocular rosacea) or cause thickening of the skin (phymatous changes). People with rosacea often experience episodes of remission and flare-ups, and some experience worsening of symptoms over time.[1][2]
Unmanaged rosacea symptoms can negatively impact quality of life and psychological well-being, leading to low self-esteem, embarrassment, and an increased risk of anxiety and depression.[3][4] A 2018 meta-analysis estimated the global prevalence of rosacea to be 5.5%, with nearly all cases occurring in adults over 30. Historically it has been thought that women are more frequently affected, but this meta-analysis found no difference in rates between men and women.[5]
