Acne rosacea, also known as rosacea, arises from multiple factors. It often stems from an impaired immune response, particularly in those with sensitive skin, leading to dryness and easy irritation. Genetics play a key role too—studies indicate that 30% of affected individuals have a family history, suggesting a hereditary component. Vascular hyperactivity, where blood vessels dilate excessively, triggers flushing and redness. Other contributors include Demodex folliculorum mites, bacteria, and prolonged sun exposure.
The hallmark is persistent redness in the central face, often with pimples and small red bumps. Skin may thicken (hypertrophy), especially on the nose, but also forehead, cheeks, chin, or ears. Itching from irritation is common, along with burning sensations and hot flashes. Ocular symptoms can include eye irritation, tearing, blurred vision, light sensitivity, and stinging.
Treatment is tailored to the subtype and symptoms. Dermatologists commonly prescribe topical agents like brimonidine to reduce redness or metronidazole for its antibacterial effects, ideal for papulopustular rosacea.
For hypertrophic rosacea, surgical options may be considered.
