Rosacea: Causes, Triggers & The Best Skincare Routine to Calm Redness

April is recognised as Rosacea Awareness Month, making it an important time to raise awareness around this common yet often misunderstood skin condition.

Rosacea can affect both your skin's appearance and confidence. While it may feel unpredictable at times, the right knowledge and skincare approach can make a significant difference in managing symptoms and supporting long-term skin health.

Rosacea is a chronic inflammatory skin condition that affects the central areas of the face, including the cheeks, nose, chin, and forehead.

It is commonly characterised by:

• Persistent redness
• Flushing
• Visible capillaries
• Sensitivity or stinging
• In some cases, acne-like breakouts

According to DermNet NZ and the Australasian College of Dermatologists, rosacea involves both inflammation and vascular dysfunction, which is why the skin can appear constantly reactive.

At Crystal Clear Skin, rosacea is managed with a focus on calming inflammation, strengthening the skin barrier, and reducing triggers over time.

There is no single cause of rosacea, but it is generally linked to a combination of internal and external factors.

Impaired Skin Barrier

A weakened skin barrier is one of the key contributors to rosacea.

When the barrier is compromised:

• Moisture is lost more easily
• The skin becomes dehydrated and reactive
• Irritants penetrate more easily

This leads to ongoing sensitivity and inflammation.

Overactive Immune Response

Rosacea-prone skin often has an exaggerated immune response to triggers.

This means the skin reacts more intensely to factors that would not normally cause irritation.

As a result:

• Inflammation is triggered more easily
• Redness becomes more persistent
• The skin struggles to return to a calm state

Vascular (Blood Vessel) Changes

Rosacea is closely linked to changes in the skin's blood vessels.

These vessels can become:

• Dilated
• More visible
• Over-responsive to triggers like heat or stress

This contributes to flushing, persistent redness, and visible capillaries.

Genetics

Genetics can play a role in the development of rosacea.

You may be more prone to rosacea if:

• It runs in your family
• You have naturally sensitive or reactive skin
• You have a fair skin type

While genetics cannot be changed, understanding this predisposition helps guide better skin management.

Environmental Triggers

External factors are one of the most common causes of rosacea flare-ups.

These include:

• Sun exposure
• Heat and extreme weather conditions
• Wind and environmental stress

Repeated exposure can weaken the skin over time, making redness and sensitivity more persistent.

Lifestyle Triggers

Certain lifestyle factors can stimulate inflammation and trigger rosacea symptoms.

Common triggers include:

• Alcohol (especially red wine)
• Spicy foods
• Stress and emotional changes
• Hot beverages

These triggers increase blood flow to the skin, leading to flushing and visible redness.

Skin Microbiome Imbalance

Emerging research suggests that changes in the skin's microbiome may contribute to rosacea.

When the balance of bacteria and microorganisms on the skin is disrupted:

• The skin becomes more reactive
• Inflammation can increase
• Sensitivity is heightened

Supporting the skin barrier and avoiding harsh products can help maintain a healthier balance.

Managing rosacea requires a gentle, consistent approach focused on calming inflammation, strengthening the skin barrier, and preventing flare-ups.
