Environment for the proliferation of demodex mites and conditions for recurrent dermatitis

I have seborrheic dermatitis and suddenly My face is getting redder , like acne The rash and pustules spread like wildfire. , especially Feeling like the epilepsy is getting worse at night If this happens, it is often difficult to explain it with just one cause.

 

Even if diagnosed with the same dermatitis, some people may have mild symptoms while others may have symptoms that last longer or have different forms. This is because different factors are simultaneously acting within the skin environment.

 

One of the frequently mentioned ones is Changes in the density of demodex mites no see.

 

Demodex mites are not something that originally did not exist.

Demodex is a parasite that everyone has on their skin.

Because it lives by eating dead skin cells and sebum, it often does not cause major problems.

 

but, A situation where the density per unit area increases Skin reactions may vary.

• Normal range: Less than 1 per 1cm²

• In case of abnormal proliferation: 10 or more detected

This difference is not simply a matter of numbers, but rather leads to differences in conditions that can influence the intensity and extent of the inflammatory response.

 

Why it often appears with seborrheic dermatitis

Demodex mite Oily skin environment I prefer .

If you have seborrheic dermatitis

• If the water-oil balance continues to be disrupted,

• It is easy for dead skin cells to accumulate

• This creates an environment where sebum control is not good.

Under these conditions, the demodex mite An environment that is easy to stay in for a long time There are cases where this is maintained.

 

So, as seborrheic dermatitis becomes chronic, it may appear as a different type of inflammation, such as rosacea, acneiform dermatitis, or pityriasis versicolor.

 

Why does inflammation spread so widely?

Demodex mites are known to have a lifespan of about two weeks, during which time they accumulate waste products in their bodies.

 

The distinctive feature is There is no excretory structure , the accumulated substances are released all at once upon death.

 

Another feature is Movement speed no see.

• About per hour 8~16cm movement

• It may feel like an inflammation that keeps changing location.

So sometimes the symptoms seem to move across the entire face rather than being confined to a specific area.

 

Why does it feel worse at night?

Demodex mite Nocturnal characteristics has.

• During the day, it hardly moves

• Moves over the skin for mating at night

During this process, you may feel more ticklishness, burning sensation, and trouble at night.

 

Because of this characteristic, the treatment approach Sometimes time zones are taken into account.

 

Background of the recent frequent mention of symptoms related to demodex

The fact that the issue of hair follicle mites has been mentioned more frequently recently is also due to changes in the skin environment itself.

Persistence of a weakened skin barrier

• Increased frequency of seborrheic dermatitis

• Prolonged water-oil imbalance

Increased cosmetics usage

• Always use sunscreen

• Oily base makeup

• Multi-layered skincare routine

Repetition of laser treatment

• Treatment without recognizing redness as dermatitis

• Post-laser dermatitis worsens → ointment → repeat treatment

• Changes in the balance of the skin's microbiome

When these factors overlap, the balance within the skin can change.

 

Symptoms that may be associated with Demodex mites

If the density of hair follicle mites increases, the following occurs: Different types of inflammatory responses It may appear as .

• Rosacea in the form of erythematous papules and pustules

• Inflammation similar to acne but with different characteristics

• Submandibular sulcus

• Rhinitis accompanied by burning sensation and itching

It is often difficult to determine that the cause is the same based on appearance alone.

 

So, even if you hear the same symptom description, someone will tell you a completely different experience.
