Rosacea: Symptoms, Causes, and Treatment

Rosacea is a long-term skin condition primarily affecting the face, leading to redness, visible blood vessels, and sometimes small, red, pus-filled bumps. It often begins after age 30 and tends to flare up periodically. While there’s no cure, treatments can manage symptoms and prevent progression.

In plain words

Rosacea is a long-term skin condition that mostly affects the face. It causes redness, visible blood vessels, and sometimes small red bumps. It usually starts after age 30. Symptoms come and go, getting better and worse over time. There is no cure, but treatments can help control symptoms. Rosacea is more common in people with fair skin and those with a family history of the condition.

What is Rosacea: Symptoms, Causes, and Treatment?

Symptoms

Early symptoms

Frequent flushing or blushing: Redness that comes and goes, especially after triggers like hot drinks or emotional stress. (1) (2)
Persistent redness: Redness in the center of the face that looks like a sunburn and doesn’t fade. (1) (2)
Visible blood vessels: Small, thin red lines (telangiectasia) on the cheeks and nose. (1) (2)
Skin sensitivity: Skin stings or burns easily with facial products, sunlight, or temperature changes. (1) (2)

Serious or emergency symptoms

Inflammatory bumps and pimples: Red, pus-filled bumps resembling acne but without blackheads. Consult a dermatologist for treatment. (2) (3)
Thickened skin: Skin thickening, especially around the nose (rhinophyma), mostly in men. Seek dermatological evaluation. (2) (3)
Ocular rosacea: Red, irritated eyes, swollen eyelids, and a feeling like something is in the eye. Consult an ophthalmologist or dermatologist. (2) (3)

Causes

Primary causes

Unknown exact cause: The exact cause of rosacea isn’t fully understood, but a combination of hereditary and environmental factors is thought to contribute. (1) (3)
Abnormalities in facial blood vessels: Facial blood vessel abnormalities may explain flushing and persistent redness. (1) (3)
Microscopic skin mites: Higher numbers of Demodex mites, a normal part of skin flora, are found in people with rosacea. (1) (3)

Risk factors

Fair skin

Fair skin that sunburns easily increases the risk of developing rosacea. (2) (3)

Family history

A family history of rosacea increases your likelihood of developing the condition. (2) (3)

Age

Rosacea often begins after age 30. (2) (3)

Diagnosis

Rosacea is diagnosed based on the appearance of your skin and your symptoms. A dermatologist will examine your skin and ask about your symptoms and flare triggers. Tests may be ordered to rule out conditions with similar symptoms, like lupus or allergic reactions. Documenting what worsens your symptoms helps confirm the diagnosis and guide treatment.

Emotional impact: Visible symptoms can lead to embarrassment, social anxiety, or diminished self-esteem. (7)
