TL;DR 

  • Poor hygiene doesn’t cause rosacea, but improper cleansing can trigger flare-ups.
  • Skipping a morning shower doesn’t directly cause rosacea but can worsen symptoms in humid climates.
  • Gentle cleansing, avoiding irritants (alcohol, fragrance, hot water), and proper hygiene (clean pillowcases, minimal face touching) help reduce flare-ups.

Many people wonder if rosacea is linked to hygiene, but the truth is, poor hygiene is not a cause of rosacea. However, certain habits can contribute to triggers that worsen the condition, especially in those predisposed to it.

Today, we’ll explore the connection between hygiene and rosacea—focusing on Demodex mites (yes, we all have them!), their role in inflammation, and how proper cleansing can help manage symptoms.

Demodex Mites: What Are They and How Do They Thrive?

Demodex mites are microscopic parasites that naturally inhabit human skin, particularly within hair follicles.

Two species commonly reside on human skin: Demodex folliculorum and demodex brevis. While everyone has demodex mites, their density varies among individuals. People with normal skin typically have a balanced population, but research has shown that those with rosacea tend to have a significantly higher density of mites. 

Demodex mites thrive in an environment with excess oil, sweat, and bacteria—proper hygiene can help manage their numbers. However, they are not inherently harmful; rather, rosacea flares have more to do with their overpopulation and the bacteria they carry.

The Link Between Demodex Mites and Rosacea

Rosacea is primarily a vascular and inflammatory condition, but numerous studies highlight the strong association between demodex mite density and rosacea severity.

Individuals with rosacea often have an impaired skin barrier and heightened inflammatory responses, providing an ideal environment for these mites to proliferate.

As these mites multiply, they carry bacteria such as Bacillus oleronius, which triggers an immune response and worsens inflammation in up to 79% of rosacea patients—Creating a self-perpetuating cycle where inflammation promotes mite proliferation, which, in turn, exacerbates inflammation.

Does Skipping Your Morning Shower Contribute to Rosacea?

In a humid climate like Singapore, skipping a morning shower can allow sweat, oil, and bacteria to accumulate overnight—creating a perfect breeding ground for demodex mites and bacteria. While a lack of a morning shower does not directly cause rosacea, it could contribute to a trigger or flare-up.

The recent online debate over morning showers in Singapore has sparked widespread discussions about hygiene and its impact on skin health, so we’d like to make it clear: While skipping a shower may not directly trigger rosacea, maintaining a clean and balanced skincare routine is essential for managing the condition.

What Triggers Rosacea?

Poor hygiene can create conditions that allow mites and bacteria to thrive, indirectly contributing to inflammation and worsening symptoms.

However, the presence of these mites is more than normal, and rosacea is more influenced by immune responses, skincare routines and skin temperature than by hygiene practices.

For example, research suggests that individuals with rosacea tend to wash their faces less frequently than those without the condition, likely due to concerns about irritation or dryness. A study found that those who used daily soap and cleansers had lower demodex mite counts, supporting the idea that proper cleansing can help manage the condition.

Conversely, over-cleansing may also be problematic. A study in China found an increased association between rosacea and individuals who washed their faces more than twice a day or took showers longer than 11 minutes. This study suggests that excessive cleansing could strip the skin’s natural barrier, leading to irritation and increased susceptibility to flare-ups.

Best Practices for Rosacea Patients

The National Rosacea Society (NRS) recommends washing your face twice daily with a gentle skincare routine. Doing so helps maintain a clean environment for the skin without stripping away essential moisture—In a survey of 1,633 rosacea patients, 78% said their facial cleansing routine helped control their rosacea symptoms. 

Key Cleansing Tips:

  • Use low-foaming, fragrance-free, and soap-free cleansers to avoid irritation.
  • If you have oily skin, use a mild soap cleanser.
  • Avoid hot or warm water, as it can trigger rosacea flare-ups.
  • Be mindful of common irritants such as alcohol, witch hazel, menthol, peppermint, and eucalyptus oil.

In surveys conducted by the National Rosacea Society, many patients reported the following ingredients as triggers for irritation:

  • Alcohol (66%)
  • Witch hazel (30%)
  • Fragrance (30%)
  • Menthol (21%)
  • Peppermint (14%)
  • Eucalyptus oil (13%)

Maintaining a consistent yet gentle cleansing routine can help keep demodex mites and bacteria under control while reducing symptoms of rosacea flares.

No Time to Shower in the Morning? Quick Hygiene Hacks

For individuals who do not have time for a morning shower, here are alternative hygiene practices to help maintain skin health:

  • Keep pillowcases and sheets clean to prevent the accumulation of oil, sweat, and bacteria.
  • Use facial wipes or micellar water in the morning to remove overnight buildup.
  • Wash your face as soon as you wake up to clear away any residue from sleep.
  • Change towels and facecloths frequently to prevent bacterial transfer.
  • Keep your hands clean and avoid unnecessary face touching.
  • Wash makeup and beauty tools once a week—Makeup sponges and brushes can harbour mites and bacteria.
  • Keep your environment cool and well-ventilated, as demodex mites thrive in warm and humid conditions.

Simple adjustments can help maintain skin hygiene without the need for a full shower every morning.

Other Tips for Rosacea Management

Skincare

  • Use gentle, fragrance-free products
  • Wash with lukewarm water; avoid hot water
  • Do not take lukewarm showers that last more than 10 minutes
  • Never pull, tug, scratch or treat your face harshly
  • Avoid any rough washcloths, loofahs, brushes or sponges
  • Men should use electric shavers rather than razors (if you must use a razor, make sure it does not have a dull blade)
  • Apply SPF 30+ sunscreen daily (UV exposure can trigger rosacea)

Diet

  • Avoid spicy foods, alcohol, and hot drinks
  • Eat anti-inflammatory foods (greens, fatty fish, berries)
  • Stay hydrated—Dehydration can exacerbate symptoms

Lifestyle

  • Manage stress (yoga, meditation, deep breathing)
  • Exercise lightly to avoid overheating (incorporate breaks or exercise in short intervals)
  • Guard rosacea-prone skin from extreme weather (cold, heat, wind)
  • Stay cool and ventilated on especially hot and humid days
  • Protect yourself from the sun by staying shaded, wearing a hat and sunglasses, and avoiding peak sunlight hours

In an NRS survey of more than 700 rosacea patients, 67% found that they could reduce the number of flare-ups they experienced through stress management techniques[10].
