Rosacea typically begins with [[erythema|reddening (flushing)]] of the skin in symmetrical patches near the center of the face.<ref name=Buddenkotte2018/> Common signs can depend on age and sex: [[flushing (physiology)|flushing]] and [[erythema|red swollen patches]] are common in the young, [[Telangiectasia|small and visible dilated blood vessels]] in older individuals, and [[rhinophyma|swelling of the nose]] is common in men.<ref name=Buddenkotte2018/> Other signs include lumps on the skin ([[papule]]s or [[pustule]]s) and [[edema|swelling]] of the face.<ref name=Buddenkotte2018/> Many people experience stinging or burning pain and rarely itching.<ref name=Buddenkotte2018/>

Skin problems tend to be aggravated by particular trigger factors, that differ for different people. Common triggers are [[ultraviolet]] light, heat, cold, or certain foods or beverages.<ref name=Buddenkotte2018/>

=== Glandular rosacea ===

In glandular rosacea, men with thick sebaceous skin predominate, a disease in which the papules are [[edema]]tous, and the [[Pustule|pustules]] are often 0.5 to 1.0&nbsp;cm in size, with nodulocystic lesions often present.<ref name="Andrews" />
