How is rosacea caused?

Rosacea is a common inflammatory skin disease with an unknown cause. Because the disease has seasonal attacks, the rash is self-limited, rarely recurs, and initially appears as prodromal spots, and no definite allergic substance has been found to cause the disease, most people believe that it is related to viral infection. During the acute phase, washing with hot water and scrubbing with soap are contraindicated. Strong irritating topical medications are prohibited. Clinically, many cases are seen where insufficient attention is paid to general treatment, thus prolonging the course of the disease or turning it into autosensitive dermatitis. Antihistamines

Antihistamines such as chlorpheniramine, cyproheptadine, terfenadine and chlorpheniramine can be used appropriately, and vitamin C can also be used. After the acute inflammatory period of ultraviolet radiation is over, ultraviolet spot irradiation can promote the disappearance of damage. Topical treatment

Calamine lotion can be applied externally.
