Understanding Rosacea: Causes, Symptoms & Triggers

22 September 2025

Rosacea is a common, chronic skin condition that primarily affects the face. It can be frustrating and sometimes even embarrassing, but with the right information and care, it can be managed effectively.

In this post, we’ll dive into what rosacea is, what causes it, the key symptoms, and what typically triggers flare-ups.

What is Rosacea?

Rosacea is a long-term inflammatory skin condition that usually affects the central part of the face—cheeks, nose, chin, and forehead. It often starts with episodes of facial flushing or redness that can come and go. Over time, the redness may become more persistent, and other symptoms can develop.

Rosacea is more common in people with fair skin and typically appears between the ages of 30 and 60. However, it can affect anyone, regardless of age or skin type.

What Causes Rosacea?

The exact cause of rosacea remains unknown, but researchers believe it results from a combination of:

Genetic factors – Family history may play a role.

Environmental factors – Sun exposure, temperature extremes, and other lifestyle factors can contribute.

Common Symptoms of Rosacea

Rosacea can vary from person to person, but common symptoms include:

Facial Redness (Erythema)

Persistent redness, especially in the central part of the face.

May look like a blush or sunburn that doesn’t go away.

Visible Blood Vessels (Telangiectasia)

Small, dilated blood vessels may become visible on the surface of the skin.

 Bumps and Pimples

Red, swollen bumps or pus-filled pimples can appear.

Often mistaken for acne, but they don’t respond to typical acne treatments.

What Triggers Rosacea Flare-Ups?

Flare-ups are often triggered by lifestyle or environmental factors. Some of the most common triggers include:

Sun exposure

Hot or cold weather.

Spicy foods

Alcohol

Stress and anxiety

Exercise

Hot beverages

Skincare products

Managing Rosacea

While there is no cure for rosacea, it can be controlled with:

Proper skincare – Use gentle, non-irritating products. Avoid exfoliants and harsh cleansers.

Prescription treatments – Topical creams, oral antibiotics, or laser therapy may be recommended

Sun protection – Daily use of sunscreen is essential.

Trigger management – Avoiding known triggers can significantly reduce flare-ups.

Final Thoughts

Rosacea can be a lifelong condition, but with proper understanding and care, it doesn’t have to control your life.

Remember, knowledge is power—and when it comes to managing rosacea, being informed is the first step to clearer, calmer skin.
