Rosacea Explained: What Causes Redness and How to Calm Your Skin

What is rosacea?

Rosacea is a common skin condition that presents as ongoing redness, flushing, visible capillaries and, in some cases, small bumps or irritation.

It often affects the cheeks, nose, chin and forehead, and can fluctuate depending on internal and external triggers.

Not all redness is rosacea, but if your skin regularly feels sensitive, reactive or flushed, it is worth understanding what may be contributing to it.

Common rosacea triggers

Rosacea is highly individual, but some of the most common triggers we see include:

  • Sun exposure and heat
  • Hot showers or saunas
  • Alcohol, particularly red wine
  • Spicy foods
  • Stress or emotional changes
  • Harsh skincare or over-exfoliation
  • Wind and environmental exposure

Understanding your personal triggers is one of the most important steps in managing redness long term.

Why your skin barrier matters

Many people with rosacea also have a weakened skin barrier. This means the skin struggles to retain moisture and becomes more vulnerable to irritation.

When the barrier is compromised, even simple products or environmental changes can trigger redness, stinging or discomfort.

If your skin often feels tight or sensitive, you may also benefit from reading our guide on dry, dehydrated and dull skin, as barrier repair is a key focus.

How to calm and support sensitive skin

Keep your routine simple

A gentle, consistent routine is often more effective than using multiple active products. Focus on calming, hydrating and protecting the skin rather than over-treating it.

Choose barrier-supporting ingredients

Look for ingredients such as:

  • Niacinamide
  • Ceramides
  • Glycerin
  • Panthenol (vitamin B5)

These help strengthen the skin barrier and reduce sensitivity over time.

Be mindful of exfoliation

Over-exfoliation is one of the most common triggers for flare-ups. If your skin is reactive, it is important to approach exfoliation carefully and avoid harsh scrubs or strong active ingredients.

SPF is essential

Sun exposure is a major trigger for redness and inflammation. Daily SPF helps protect the skin and reduce flare-ups over time.

In clinic treatments that can help

While home care plays an important role, professional treatments can provide additional support for persistent redness and sensitivity.

LED Light Therapy

LED light therapy is a gentle, non-invasive treatment that can help calm visible redness and support the skin’s natural repair process. It is often a great starting point for sensitive skin types.

Laser Genesis and vascular laser treatments

Treatments such as Laser Genesis or vascular lasers can help target visible redness and support a more even skin tone over time. These are always recommended based on your individual skin and suitability.

If redness is part of a broader skin concern, your clinician may also look at supporting concerns like pigmentation and uneven tone as part of your treatment plan.

Recommended skincare for rosacea-prone skin

Using the right skincare at home can make a significant difference in how your skin feels day to day.

When choosing products, look for formulations that:

  • Support hydration and barrier repair
  • Avoid strong fragrances and irritants
  • Focus on calming and strengthening the skin

Our team can guide you on suitable options available in clinic, tailored to your skin type and sensitivity levels.

A personalised approach is key

No two cases of rosacea or redness are the same. What works for one person may not be suitable for another.

The most effective way to manage redness is through a personalised approach that considers your skin, your triggers and your lifestyle.

Clinician-Recommended Skincare for Rosacea-Prone Skin

When your skin is reactive or prone to redness, choosing the right skincare can make a significant difference in how your skin feels day to day.

Rather than focusing on trends or overly active products, the priority is calming inflammation, supporting the skin barrier, and maintaining hydration.

Some of the products our dermal clinicians may recommend include:

Pevonia Soothing Propolis Concentrate

This calming serum is designed to support sensitive and reactive skin, helping to reduce visible redness while strengthening the skin barrier.

Ultraceuticals MD RED Serum

A targeted formulation designed to support redness-prone skin, helping to calm visible flushing and improve overall skin comfort.

Dermaquest Soothing Antioxidant Serum

This antioxidant-rich serum helps protect the skin while supporting hydration and reducing environmental stress that can trigger flare-ups.

Pevonia RS2 Cream

A nourishing, calming moisturiser designed specifically for sensitive and redness-prone skin, helping to soothe irritation while supporting long-term barrier repair.

These products are not available for online purchase and are only recommended and dispensed in clinic following a professional consultation.

This ensures that every product is carefully selected based on your skin type, level of sensitivity, and individual triggers, rather than a one-size-fits-all approach.

Book a Skin Consultation

If you are experiencing ongoing redness, sensitivity or flushing, a professional Visia skin consultation at our Geelong skin and laser clinic is the best place to start.

Our dermal clinicians will assess your skin, identify potential triggers, and guide you on both treatment options and the most suitable in-clinic skincare for your skin.
