What Is Rosacea?

Rosacea is a chronic inflammatory skin condition that primarily affects the face, leading to redness, visible blood vessels, and sometimes acne-like breakouts. It often begins after age 30 and can persist with periods of flare-ups and remissions. While it is not curable, rosacea can be managed with appropriate treatment and lifestyle adjustments.

What Causes Rosacea?

The exact cause of rosacea is unknown, but several factors may contribute to its development:

• Genetic predisposition: A family history of rosacea increases the risk.
• Environmental triggers: Factors such as sun exposure, hot or cold temperatures, spicy foods, alcohol, and stress can exacerbate symptoms.
• Immune system abnormalities: An overactive immune response may play a role.
• Skin mites: The presence of Demodex mites on the skin has been associated with rosacea, though their exact role is not fully understood.

What Are the Symptoms of Rosacea?

Common symptoms include:

• Persistent redness in the central face, particularly on the nose, cheeks, chin, and forehead.
• Visible blood vessels (telangiectasia).
• Acne-like pimples and pustules.
• Skin that stings, burns, itches, or feels tight.
• Swelling of the face.
• Eye irritation, including dryness, redness, and a gritty sensation.

How Is Rosacea Diagnosed?

Diagnosis is primarily based on:

• Medical history and physical examination: A healthcare provider will assess the patient’s symptoms and appearance.
• Exclusion of other conditions: Tests may be conducted to rule out conditions with similar symptoms, such as acne or lupus.

Treatment Options for Rosacea

While there is no cure for rosacea, treatments aim to control symptoms and prevent flare-ups:

• Topical medications: Such as metronidazole, azelaic acid, or ivermectin to reduce inflammation and redness.
• Oral antibiotics: In cases with pustules or papules, oral antibiotics like doxycycline may be prescribed.
• Laser therapy: To reduce visible blood vessels and redness.
• Lifestyle modifications: Identifying and avoiding personal triggers, using gentle skincare products, and applying sunscreen regularly.

Can Rosacea Cause Complications?

If left untreated, rosacea can lead to complications such as:

• Rhinophyma: Thickening of the skin on the nose, leading to a bulbous appearance.
• Eye problems: Including dryness, irritation, and in severe cases, vision problems.

How Can Rosacea Be Prevented?

While rosacea cannot be prevented, its symptoms can be managed by:

• Avoiding known triggers: Such as sun exposure, hot beverages, spicy foods, and stress.
• Using gentle skincare products: Avoiding harsh chemicals and fragrances.
• Applying sunscreen daily: To protect the skin from UV rays.
• Maintaining a consistent skincare routine: To soothe and protect the skin.
