Understanding the Causes and Treatments of Rosacea

by | May 10, 2024 | Uncategorized | 0 comments

Rosacea is a common skin condition that affects millions of people worldwide. 

Characterised by redness, visible blood vessels, and sometimes small, red, pus-filled bumps on the face, rosacea can vary in severity and can impact both the skin and the eyes. 

This blog will explore the causes of rosacea and discuss the available treatments that can help manage this chronic condition.

What Causes Rosacea?

The exact cause of rosacea remains unknown, but it is believed to be a combination of hereditary and environmental factors. 

Several potential triggers may contribute to its onset or exacerbate its symptoms:

Genetic Factors

Rosacea often runs in families, suggesting a genetic predisposition. If your parents or siblings have rosacea, you may be more likely to develop the condition.

Blood Vessel Abnormalities

Some studies suggest that abnormalities in the blood vessels of the face could cause the increased redness and flushing seen in rosacea.

Demodex Mites

These tiny skin mites are a normal part of the skin’s microbiome but are found in greater numbers on the skin of people with rosacea. It’s not clear if they cause rosacea or if they thrive because of it.

Bacterial Involvement

The presence of certain bacteria, like Helicobacter pylori, which is often found in the gut, has been linked to rosacea. This bacteria may cause increased levels of certain proteins that could trigger inflammation.

Environmental Triggers

Exposure to sunlight, extreme temperatures, hot drinks, spicy foods, alcohol, stress, and even certain skincare products can trigger or worsen rosacea symptoms.

Can Rosacea Be Treated?

While there is no cure for rosacea, there are many effective treatments available that can control or reduce the signs and symptoms of the disease. 

Treatment choices depend on the severity and type of rosacea present:


Topical and oral medications can help reduce inflammation and clear up acne-like pimples. Commonly prescribed medications include topical metronidazole, azelaic acid, and ivermectin, as well as oral antibiotics like doxycycline.

Laser Therapy

Laser treatment can reduce redness by targeting enlarged blood vessels. It is often used for more persistent cases of rosacea that do not respond well to topical treatments.

Lifestyle Modifications

Identifying and avoiding individual triggers can play a crucial role in managing rosacea. Keeping a diary of flare-ups may help to pinpoint specific triggers. 

Additionally, using gentle skincare products and protecting the skin from extreme temperatures and sun exposure with a broad-spectrum sunscreen can prevent exacerbation.

Skincare Treatments

Gentle daily skincare routines are vital. The use of mild cleansers, moisturisers, and products labelled for sensitive skin can help maintain the skin’s integrity and reduce irritation.

Dietary Changes

For some people, certain foods and drinks can trigger rosacea flare-ups. Avoiding hot drinks, spicy foods, and alcohol may help reduce symptoms.

Understanding what triggers your rosacea and how to manage it is key to living comfortably with this condition. 

With the right combination of treatments and lifestyle changes, most people with rosacea can achieve significant improvement in their skin condition.
