An Aesthetic Doctor's Honest Take on Treating Rosacea-Prone Skin

In my clinic in Ireland, rosacea is one of the skin conditions I see most often. And when I ask patients what they are currently doing about it, the answer is almost always the same: "I just cover it with concealer."

It is a response I hear so frequently that it has become something of a mission for me - to show patients that there is a much better way.

Rosacea is one of the most common chronic skin conditions in Northern Europe. Fair phototypes, genetic predisposition, and cooler, changeable climates mean that Celtic and Northern European skin types show some of the highest rates globally. If you have rosacea, you are far from alone - and far from out of options.

What Rosacea Actually Looks Like

Rosacea is a long-term inflammatory disorder affecting the central face. It is not dangerous, but it can significantly affect comfort, confidence, and quality of life - especially when it goes unmanaged for years.

The most common symptoms include:

• Persistent facial redness
• Flushing triggered by heat, stress, alcohol, or spicy food
• Visible small blood vessels (telangiectasia)
• Papules and pustules without comedones
• Burning, stinging, and skin sensitivity
• Dryness and an impaired skin barrier
• Ocular symptoms such as dryness or irritation

Rosacea follows a relapsing pattern - periods of flare followed by periods of relative calm. Understanding this cycle is the first step to managing it properly.

The Rules I Give Every Rosacea Patient

Before any treatment or active ingredient, the foundation has to be right. Here is what I advise every rosacea-prone patient:

• Wear SPF 50 every day - mineral formulas are generally far better tolerated on reactive skin
• Use a gentle, non-foaming cleanser - nothing that strips or over-cleanses
• Prioritise barrier repair with ceramides, lipids, and panthenol
• Identify and avoid your personal triggers - UV, wind, temperature extremes, hot drinks, alcohol, spicy food, stress, and vigorous exercise are the most common
• Avoid harsh exfoliants, scrubs, and strong acids - these inflame an already reactive skin
• Avoid overheating the face - hot showers, steam rooms, and saunas are not your friend
• Introduce active ingredients slowly, and only during periods of remission

Topical Actives Worth Knowing About

Once the basics are in place, there are several well-researched ingredients I use to target specific aspects of rosacea:

• Azelaic acid - one of my most-used recommendations; it targets redness, papules, pustules, and post-inflammatory erythema
• Brimonidine - for persistent redness and flushing
• Ivermectin (topical) - particularly effective for inflammatory bumps and Demodex-associated rosacea
• Metronidazole (topical) - reduces inflammation, papules, pustules, and sensitivity
• Niacinamide (low concentration) - supports barrier repair and calms redness
• Ceramides, lipids, and panthenol - essential for anyone with dryness, stinging, or barrier impairment
• Mineral SPF - non-negotiable; UV is one of the most consistent rosacea triggers

The Clinic Treatments That Make a Real Difference

Skincare alone can take you a long way, but for patients who want to go further - or whose barrier is significantly compromised - clinic treatments can be genuinely transformative.

At Sisu, two treatments stand out for rosacea-prone skin:

Profhilo

Profhilo is a highly purified hyaluronic acid treatment that works beneath the surface to improve hydration, stimulate collagen and elastin, and enhance overall skin quality.

For rosacea patients, this is significant. A compromised skin barrier is one of the most consistent features of the condition - when the barrier is weak, the skin becomes more reactive and more prone to flaring. Profhilo helps restore structural integrity from within, making the skin more resilient and better able to tolerate environmental triggers and active ingredients.

Patients often notice improved texture, reduced sensitivity, and a calmer overall complexion after a course of treatment.

Polynucleotides

Polynucleotides are one of the most exciting developments in regenerative aesthetics - and for rosacea-prone skin specifically, they are genuinely impressive.

Derived from purified DNA fragments, they work by stimulating the skin's own repair mechanisms - reducing chronic inflammation, improving barrier function, and decreasing reactivity over time. In my experience, patients who combine polynucleotides with a solid skincare routine see meaningful improvements in sensitivity, redness, and flare frequency.

This is not just symptom management. It is helping the skin to function better at a cellular level.

Supplements That May Provide Additional Support

These are not treatments for rosacea, but they are commonly discussed in dermatology for supporting barrier function and inflammation balance:

• Omega-3 fatty acids
• Vitamin D
• Zinc
• Probiotics
• B-complex, especially B3/niacinamide orally
• Always speak to your GP before starting any new supplement.

Rosacea is common, it is manageable, and you deserve more than a layer of concealer. With the right skincare foundations, the right clinic support, and a doctor who understands your skin, you can dramatically reduce flares, improve resilience, and feel genuinely comfortable in your skin again.

There is more to rosacea management than concealer.
