Key facts about Rosacea

Published 22nd March 2017

Expert Reviewed By

Rosacea is one of those skin conditions that many people have heard of, but very few truly understand. What makes rosacea particularly challenging is how differently it presents from person to person, from mild flushing to more persistent redness and skin changes. In this article, we share 7 key facts about rosacea that many people don’t realise. These insights help clear up common myths and explain why rosacea is so often misunderstood.

So What is Rosacea?

First let’s talk about what rosacea is. is a chronic inflammatory disease of the skin, which mainly affects the central part of the face on the cheeks, nose and forehead. Classic signs include:

Rosacea is primarily a skin condition, but it can also affect the eyes in some people.

Here are 7 key facts about rosacea you might not know…

1 Rosacea affects around 1 in 10 adults in the UK.

Rosacea is far more common in the UK than most people realise, yet it is still widely misunderstood and underdiagnosed.

2. Rosacea is often misdiagnosed as acne or allergies.

Rosacea can be confused with , as it can look similar. However, there is a key difference: rosacea does not cause blackheads or whiteheads (comedones). Instead, it causes red inflamed bumps and flushing across the central face.

Unlike allergies, usually does not itch. Allergies tend to be itchy, whereas rosacea mainly affects how the skin looks rather than how it feels.

3. Men are more likely to develop severe forms, even though women are diagnosed more often.

is more commonly seen in women, but when men develop it, it is more likely to progress to thickened skin changes such as rhinophyma. There is often a family history, and studies show that both genetics and environment influence whether someone develops symptoms.

4. It’s not caused by poor hygiene; triggers are mainly environmental and genetic.

You cannot "catch" rosacea from someone else, meaning it is not contagious and it is not connected with poor hygiene.

5. Sun exposure is the biggest trigger for most people.

While triggers of rosacea vary from person to person, sunlight is by far one of the most common. According to surveys by the , sun exposure is the most common factor causing flare-ups, noted by 81% of patients. Sunlight causes heating of the skin, which triggers a complex biological reaction, causing visible blood vessels to expand. This is why daily sun protection is such a key part of managing rosacea.

6. Some types of rosacea are invisible.

Certain types and stages of rosacea can be "almost invisible" in certain stages or skin tones. Not everyone with rosacea has constant redness or spots. Some people only experience that comes and goes, with heat, stress or certain foods and drinks.

Rosacea can present very on darker skin tones. We explain how signs can look subtle or distinct from classic redness in our article on

7. Early treatment can prevent worsening and visible skin changes.

Rosacea is a progressive inflammatory condition. Starting treatment early can help:

and ZO Medical are to treat symptoms, such as flushing, redness, prominent blood vessels, papules and pustules.

Rozatrol is a new ZO Medical treatment product, which is used within a personalised ZO protocol. It relieves visible signs and symptoms, normalising skin by reducing excess oil, it decreases inflammation. As an enzymatic exfoliator, it provides ultra-mild exfoliation. The amino acids support optimal microcirculation preventing the signs of premature ageing. Rozatrol can be used on red, sensitised skin.

Rhinophyma (pictured) is a slowly progressive condition caused by hypertrophy of the sebaceous glands on the tip of the nose. It presents as a pink lobulated mass over the nose with superficial vascular dilation. Left untreated, these growths enlarge and can obstruct breathing and vision.
