Rosacea develops from a mix of factors: abnormal reactivity of facial blood vessels, chronic low‑grade inflammation, changes in the skin’s microbiome (including Demodex mites), genetics, and environmental triggers like UV, heat, and alcohol. It is not caused by poor hygiene and is different from acne, although both can occur together.
Rosacea itself is not life‑threatening, but without control it can lead to permanent redness, visible vessels, skin thickening, and eye problems. It often causes a strong cosmetic and psychological burden, so early diagnosis and steady treatment are important.
Rosacea treatment is long‑term and tailored: gentle skincare, daily sun protection, trigger avoidance, and prescription creams or gels are the base. Depending on the subtype and severity, doctors may add oral medications, laser or light treatments for vessels, and sometimes surgery for advanced thickening of the nose or other areas.
