Previously, a diagnosis of rosacea involved categorization into one of four subtypes:
- Erythematotelangiectatic (flushing, redness, visible blood vessels)
- Papulopustular (papules, pustules, redness, inflammation)
- Phymatous (nodular growths, bulbous nose, dilated follicles)
- Ocular (eye irritation/sensitivity, scaly/red eyelids, eye inflammation)
However, current recommendations have moved away from subtyping, as people with rosacea often experience overlaps between subtypes and progression from one subtype to another. [1][2]
