What It Is
Rosacea: Rosacea is a long-term skin condition that typically affects the face. It results in redness, pimples, swelling, and small and superficial dilated blood vessels. Often, the nose, cheeks, forehead, and chin are most involved. A red, enlarged nose may occur in severe disease, a condition known as rhinophyma.
Why It Happens
Rosacea arises due to factors affecting the Integumentary System (Skin). Skin conditions arise from immune-mediated inflammation, infections, allergen exposure, UV damage, or disruptions in the skin barrier. While individual cases vary, a combination of genetic susceptibility, lifestyle factors, and environmental exposures typically contribute to the development of Rosacea.
Who Gets It / Risk Factors
Who Is at Risk for Rosacea
Varies by condition—acne and eczema are common in younger age groups, while skin cancers and chronic conditions increase after 40.
A family history of integumentary system (skin) conditions may increase susceptibility to Rosacea.
Contributing Factors
UV exposure without protection, genetic predisposition to atopy, occupational chemical exposure, and immune suppression.
Co-existing health conditions such as autoimmune disorders, allergies, or metabolic conditions may compound the risk.
When to Seek Emergency Care
Rapidly spreading rash with fever, large blistering, signs of anaphylaxis, or a rapidly changing mole related to Rosacea.
Sudden or rapidly worsening symptoms that impair basic daily function.
Difficulty breathing, severe pain, loss of consciousness, or high fever with confusion.
