What is Rosacea?

Rosacea is a chronic skin condition that primarily affects the face, causing redness, flushing, visible blood vessels (telangiectasia), and sometimes acne-like bumps. It often begins with a tendency to blush or flush more easily than other people. Over time, the redness can become more persistent and noticeable, especially on the cheeks, nose, chin, and forehead.

There are four subtypes of rosacea:

1. Erythematotelangiectatic Rosacea – persistent redness and visible blood vessels.

2. Papulopustular Rosacea – redness with acne-like breakouts.

3. Phymatous Rosacea – thickened skin, often on the nose (rhinophyma).

4. Ocular Rosacea – affects the eyes, causing dryness and irritation.

Rosacea is more common in individuals with fair skin, typically between the ages of 30 and 50, but it can affect anyone.

 

What causes rosacea?

While the exact cause of rosacea is still unknown, several factors are believed to contribute, including:

• Genetics – it often runs in families.

• Immune system response – particularly an overreaction to environmental or internal triggers.

• Demodex mites – microscopic skin mites that live on the skin and may be more prevalent in people with rosacea.

• Environmental triggers – such as sun exposure, extreme temperatures, spicy foods, alcohol, and stress.

• Abnormal blood vessels – increased blood flow in the skin may contribute to the persistent redness.

Rosacea is not contagious, but it can significantly affect one’s self-confidence and quality of life if left untreated.
