I believe that everyone has brushed a lot of pushes about mites on various platforms!
Before there are tens of millions of dust mites sleeping in the nest with you, after a million worm mites on your face to party.
Recently, Benhua has also brushed a lot of facial cleaning products that claim to be able to remove mites in a certain sound and a certain red book.

Some merchants even directly attribute a series of skin problems such as skin oil, blackheads, and acne to mites in the pores.
Let's just say that it is not necessary (mite: refuse to carry the pot), in order to avoid the sisters on this new IQ tax, today we will get to know the demodex mite.
What is a demodex mite
A demodex mite is a permanent parasitic mite that predominates on areas where hair follicles and sebaceous glands are developed, such as the flanks of the nose, cheeks, forehead, eyelids, chin, and thorax, feeding on the host's sebum secretions and keratins, and is transmitted mainly through direct or indirect contact.
Effects on the skin
First of all, it should be clear that demodex mites are conditionally pathogenic parasites and are usually harmless to the human body.
However, when your immunity is weakened or if you have other bacterial infections, it is also possible to induce a local immune inflammatory response.
The pathogenicity of demodex mites is mainly reflected in the following aspects:
Mechanical, chemical stimulation
Human demodex mites grow and multiply in hair follicles and sebaceous glands, nibble on the mouthparts, crawl and crawl, excrete feces, mate and lay eggs, and rot and liquefaction after the death of adult worms, which will constitute certain mechanical irritation and physical and chemical stimulation of the skin, and easily aggravate the inflammation of the skin itself.
anaphylaxis
After death, demodex mites will excrete on our skin at one time, these corpses and stools are foreign bodies and xenopses to human skin tissue, and some people are prone to immune allergic reactions (allergic reactions).
Pathogenic microbial infection
The mating of human demodex mites is carried out on the surface of the skin, so when the human demodex mites mate and the external environment of the skin changes significantly, such as too high and too low, it will crawl to the surface of the skin.
In this way, when mites enter and exit the pores, they can bring pathogenic microorganisms on the surface of the skin into the hair follicles and sebaceous glands, so that the skin shows symptoms of infection, such as redness, swelling, heat and pain, papules and so on.
Is "mite removal" skin care products necessary?
First of all, the conclusion is not significant, because there are also demodex mites on normal skin.
Most of the anti-mite skin care products on the Internet claim to be able to achieve the purpose of acne removal, blackheads and even shrink pores through mite removal.
Regardless of whether its ingredients can really kill mites, the correlation between acne and demodex mites is still inconclusive, and it is impossible to dump skin problems on demodex mites.
Secondly, as mentioned earlier, the carcass and poop of the demodex mite are the factors that trigger the immune allergic reaction, and the mass removal of mites produces corpses that are more likely to induce allergies.
Let's not pay that IQ tax.
Treating the root causes of the disease is key
Demodex mites can be said to be permanent residents of human hair follicle sebaceous glands, 80%-90% of people have demodex mites, under normal circumstances, everyone can coexist peacefully, well water does not violate the river water.
For people with unhealthy skin, the presence of demodex mites is only a cause of skin inflammation, not the main cause. If the mites are simply removed, the skin problem is likely to persist.
Therefore, if there are skin problems, such as acne, rosacea, you should seek medical treatment for the primary disease, if the number of demodex mites is too large, then cooperate with anti-mite therapy under the advice of the doctor, such as topical 5% permethrin cream, sulfur, or oral ivermectin and metronidazole.
Learn to live in peace
Usually demodex mites are not pathogenic, but more often than not, it is because of your bad habits that they are "wanton".
If you want to make the demodex mite "converge", you still have to do the same three things that we often emphasize: cleaning- moisturizing - sunscreen.
Doing a good job of daily cleaning and removing excess oil can reduce the "food supply" to demodex mites. At the same time, pay attention to moisturizing and sun protection can help to develop a healthy skin barrier.
In addition, establishing good work and rest habits and a balanced diet to maintain skin barrier function and sebum secretion in a healthy state can coexist peacefully with demodex mites.
