What Causes Rosacea Flare Ups

Rosacea is a chronic inflammatory condition.

It is closely associated with skin sensitivity and is influenced by various triggers.

Environment, central heating, alcohol, spicy foods and even mites.

Because rosacea is such a tricky condition to navigate, we put together this article and this free ebook.

Here, we look at what causes rosacea and how to treat it.

Understanding Rosacea

What Rosacea? Pronounced as “ro-zay-sha,” rosacea is a persistent skin condition characterised by facial redness.

It is a vascular disorder that prompts blood vessels to enlarge, increasing blood flow to your skin.

An unknown factor in the bloodstream triggers tiny capillaries and blood vessels to swell, causing continuous flushing and inflammation, especially around the cheeks and nose, and, in severe cases, thickened skin.

Typically, rosacea develops in adulthood and is a frequent cause of adult acne.

Sensations of Rosacea

Rosacea will often present as physical sensations before visible symptoms emerge.

Familiar sensations include skin burning, tightness, dryness, and itching. They can resemble a heat rash or sunburn and are accompanied by mild, persistent throbbing or discomfort.

Some individuals with rosacea may also experience a burning, gritty feeling in their eyes.

Appearance of Rosacea

This condition tends to be more prevalent in fair-skinned individuals who blush easily.

During flare-ups, your skin may appear mottled and purple, with a predominant presence on your cheeks.

In rare instances, rosacea may extend to your back and chest.

On calmer days, persistent redness will often remain due to your broken capillaries or veins scattered across your Tzone area.

To the untrained eye, rosacea can resemble acne, occasionally featuring pus-filled breakouts.

Recognising the Signs

Let’s drill down on some of these common signs and symptoms that could indicate your troublesome skin condition is, in fact, rosacea:

  1. Flushing: Frequent and persistent facial flushing that often resembles sudden redness or blushing.
  2. Redness: A general skin redness, primarily on the central face, nose, and cheeks.
  3. Flaky Skin: If your skin is affected by rosacea, you may notice dry patches.
  4. Large Pores: Rosacea can cause your pores to enlarge, especially in areas with persistent redness.
  5. Inflammation: Inflammatory responses are common in rosacea; you may experience swelling and discomfort.
  6. Pus-filled Spots: It’s common to experience papules and pustules, small, pus-filled spots often mistaken for acne.
  7. Facial Swelling: Swelling or puffiness of your face may be apparent when your rosacea flare-ups.
  8. Pink, Itchy Eyes: Rosacea can affect your eyes, leading to symptoms like pink eye and uncomfortable itching.
  9. Tiny Distended Veins: Small, visible blood vessels or tiny distended veins may become noticeable on your skin’s surface.
  10. Broken Capillaries: Rosacea often leads to the development of broken capillaries or visible blood vessels, contributing to your persistent redness.
  11. Thickening of Facial Skin: In severe cases, rosacea can cause skin thickening, especially around your nose.
  12. Congestion and Nose Deformity: Rosacea can lead to nasal congestion and, in rare instances, nose deformity, resulting in a condition called rhinophyma.

If you notice these signs, it’s essential to consult a dermatologist for a proper diagnosis and tailored treatment to manage your rosacea effectively.

What Causes Rosacea

The exact cause of rosacea remains a subject of ongoing research; several factors are believed to contribute to this complex skin condition:


This study (1) at Stanford University School of Medicine has suggested a genetic basis for rosacea.

They discovered specific genetic associations near genes involved in inflammatory and autoimmune diseases, implying a genetic predisposition.

Environmental Triggers

This research (2) found that common environmental factors are known to trigger or exacerbate rosacea. These triggers include exposure to UV radiation, temperature changes, harsh irritants, spicy foods, and alcohol.

These external factors stimulate the sensory nervous system, which plays a role in rosacea flare-ups.

Microscopic Organisms

Demodex mites, naturally present on the skin and part of the body’s microbiome, have been associated with rosacea.

An overabundance of these mites may trigger an immune response and inflammation.

Additionally, bacteria linked to these mites, particularly Bacillus oleronius, have been found to stimulate inflammatory responses in individuals with rosacea.

The National Rosacea Society (NRS) carried out a study (3) on this and found that these bacteria stimulated an inflammatory response in 80% of the participants with rosacea.

To conclude. The naked truth

When considering what causes rosacea, you must understand it is a multifaceted skin condition with various potential triggers, including genetic predisposition, environmental factors, and associations with microscopic organisms like Demodex mites and bacteria like Bacillus oleronius.

While the exact cause remains under investigation, understanding these factors can provide valuable insights into managing and preventing rosacea flare-ups.

If you suspect you have rosacea based on the described signs and symptoms, seek medical advice and get a correct diagnosis for appropriate treatment.

Rosacea is a complex condition, but its impact can be effectively minimised with proper care.

I just want to say thank you Samantha for your amazing products! I’m a 37 year old male in the USA that has been suffering from Rosacea since my early 20’s and have gone to numerous Dermatologist & spas who would prescribe all kind of different steroid creams which would leave my face oily and wouldn’t address the redness and after time was thinning my skin. A month into trying your fortify cream along with your miracle cleanser face wash and your H2O skin shot my face has improved 100 % ! I’ve had people literally tell me my skin looks great, which has never happened before so thank you so much and I’m so happy I finally found your natural products which don’t irritate my skin like all the others did in the past. I will be trying two more of your products this week which are your SOS skin shot & DNA . Thank you again and you have a life customer here.

I don’t know if this helps, but I was diagnosed with a lactose intolerance once this cleared up my rosacea subsided

I am a rosacea sufferer and find it so difficult to treat, once the skins barrier is impaired it is really hard to fix, do you have any suggestions, thanks in advance ..
