Why Is My Skin So Red? A Honest Guide to Understanding Rosacea
By Hannah Tress | Hannah Tress Advanced Skincare, Hampshire
For years, I told myself my red skin was just something I had to live with. Maybe it was sensitive skin. Maybe it was my colouring. Maybe I was just someone who flushed easily.
It wasn’t until I understood what was actually happening in my skin that everything started to make sense – and things began to change.
If you’ve been asking yourself why your skin is always red, why certain things make it worse, or why nothing you try seems to calm it down for long, this is for you.
What rosacea actually is (and what it isn’t)
Rosacea is a chronic inflammatory skin condition that primarily affects the central face – the cheeks, nose, chin, and forehead. It’s more common than most people realise, affecting an estimated one in ten people in the UK, and it’s particularly prevalent in women aged 30 and above.
But here’s what’s important to understand: rosacea isn’t just redness. It’s a condition rooted in chronic inflammation and a compromised skin barrier, and it often involves a vascular system that over-responds to triggers – heat, stress, hormones, certain foods, and more.
It’s also frequently misunderstood, which means many people are managing it incorrectly for years – using products that feel good in the moment but are silently making things worse.
The four main types
Rosacea doesn’t look the same on everyone. There are four subtypes, and many people have a combination:
Erythematotelangiectatic rosacea (ETR) – persistent redness, flushing, and visible blood vessels. This is the most common type and what most people picture when they think of rosacea.
Papulopustular rosacea – redness combined with breakouts that look like acne, but aren’t. This is sometimes called “adult acne” in error, and treating it like acne can make it significantly worse.
Phymatous rosacea – thickening of the skin, most often around the nose. More common in men.
Ocular rosacea – affects the eyes, causing dryness, irritation, and redness. Often overlooked because people don’t connect eye symptoms to a skin condition.
Why does rosacea happen?
The honest answer is that we don’t have a single cause. Rosacea is multifactorial, meaning it’s influenced by a combination of genetics, immune responses, and environmental factors.
What we do know is that the skin barrier in rosacea-prone skin is typically compromised. The protective outer layer of the skin – which should keep irritants out and moisture in – is weaker than in healthy skin. This means external triggers can penetrate more easily, setting off an inflammatory cascade.
We also know that the vascular system in rosacea skin is unusually reactive. Blood vessels near the surface dilate in response to triggers that wouldn’t cause a response in most people, which produces that characteristic flushing and persistent redness.
There’s also a growing body of research connecting rosacea with gut health, particularly the gut microbiome. Studies have found higher rates of conditions like small intestinal bacterial overgrowth (SIBO) in rosacea patients, which suggests that for some people, working on gut health is genuinely part of managing the condition – not just an optional wellness add-on.
Hormones play a role too. Many women notice their rosacea worsening during perimenopause, when falling oestrogen levels affect skin barrier function, hydration, and the skin’s inflammatory response. If you’re in your 40s and feeling like your skin has changed in ways that don’t quite add up, hormones are very likely part of the picture.
Common triggers – and why identifying yours matters
Rosacea is highly individual. What triggers a flare in one person may have no effect on another. The most commonly reported triggers include heat and temperature changes, sun exposure, alcohol (particularly red wine), spicy food, stress, certain skincare ingredients such as alcohol and fragrance, and hormonal fluctuations.
Keeping a simple trigger diary for a few weeks can be genuinely transformative. Patterns often emerge that aren’t obvious until you see them written down.
The skincare mistakes that make rosacea worse
This is where I see the most damage – and it usually comes from good intentions.
Over-cleansing strips the natural oils the skin desperately needs. Harsh cleansers, double cleansing with actives, and foaming formulas all compromise the barrier further.
Over-exfoliating is another common issue. Exfoliating acids increase skin sensitivity and can significantly worsen vascular reactivity – yet many rosacea sufferers are advised to use them.
Using too many products at once is overwhelming for inflamed skin. When the barrier is compromised, simplicity is everything.
Avoiding SPF because it irritates is understandable, but sun protection is non-negotiable in rosacea management. The key is finding the right formula – mineral SPF, using zinc oxide or titanium dioxide rather than chemical filters, is generally far better tolerated.
What does effective rosacea treatment look like?
Managing rosacea well requires a layered approach. In my clinic, I work with a 360° model that addresses the skin from the outside in – and the inside out.
The two treatments I use most for rosacea are IPL (Intense Pulsed Light) and Dermalux LED therapy. IPL targets visible blood vessels that cause persistent redness, selectively treating them without damaging the surrounding skin. Dermalux LED works at a cellular level to reduce inflammation, support barrier repair, and calm the vascular reactivity that drives flushing and redness.
Alongside in-clinic treatments, I place equal importance on home skincare, nutrition, gut health, and stress management. For many of my patients, making changes in these areas alongside clinic treatment is what finally produces lasting results rather than temporary improvement.
A note from me
I don’t just understand rosacea professionally. I’ve lived it.
At my worst, I had all three of the main subtypes simultaneously. I had erythematotelangiectatic rosacea – the persistent flushing and visible vessels across my cheeks. I had papulopustular rosacea – the breakouts that look like acne but aren’t, and that so many people, including practitioners, mistake for acne and treat entirely the wrong way. And I had ocular rosacea, which for me meant chronic blepharitis, regular styes, and eyes that were constantly irritated and inflamed.
It was relentless. And like so many of my patients, I spent years trying to manage it from the outside – better products, gentler routines, avoiding triggers – without ever fully addressing what was driving it underneath.
What changed things for me wasn’t one treatment or one product. It was approaching my skin as a whole-body health issue. I worked on my gut – seriously, consistently, with targeted supplementation and real attention to my microbiome. I changed how I moved, adjusting my exercise to support my nervous system rather than spike my cortisol. I looked at when I was eating, not just what. I rebuilt my skin barrier slowly and patiently, with the right ingredients at the right time.
Those three things together – gut health, nervous system regulation, and barrier repair – combined with time, are what brought my rosacea into remission. It’s been six months now. I don’t use the word cured, because rosacea doesn’t work that way. But my skin is calm in a way I honestly didn’t believe was possible for me.
That experience is why I work the way I do. Every patient I see with rosacea gets the same 360° approach – not because it’s a nice idea, but because it’s what actually works. I’ve seen it in my own skin, and I see it in my patients’ skin too.
If you’re tired of being told to just avoid your triggers and use a gentle cleanser, I’d love to talk.
