It is said that the habit of wearing masks has led to an increasing number of people saying that their skin condition has deteriorated regardless of the season or gender. This is also because the coined word "maskne (maskne, mascne, etc.)" was born, which is a combination of "mask" and "acne", an acne bacterium that is considered to be one of the causes of acne. I know.

Knowing the cause of acne and rough skin caused by wearing a mask will help prevent deterioration. In addition, by dealing with the skin troubles that have occurred with beauty care, it can be expected that the skin quality will be improved and healthy skin will be maintained continuously.

Three causes of acne and other rough skin in long-term mask life

Symptoms of rough skin and acne that occur in mask life and methods that can be expected to improve

It is said that if you continue to wear a mask for a long time as a countermeasure against infectious diseases, skin problems such as acne, redness of the skin, and pores will become more noticeable.

According to overseas research presentations, as a result of having multiple subjects wear masks for 6 hours a day for 2 weeks, skin elasticity decreased, pore volume and acne increased [*] 1] is shown.

First, I will explain the main causes of skin problems such as acne and rashes caused by long-term mask life.

[* 1] Reference: Influence of quarantine mask use on skin characteristics: PubMed

Stimulation due to friction with the mask

Friction occurs between the mask and the skin when putting on and taking off the mask, correcting the misalignment, and when talking and moving the mouth while wearing the mask. Friction irritation is said to be the most common cause of rough skin caused by long-term mask life. The friction created by the repeated rubbing of the mask fibers and the skin stimulates the surface of the skin (shallow layer), which can cause the skin to become rough and cause acne and rashes.

Skin trouble caused by friction

Acne

The skin is not a simple layer, but is divided into a shallow layer, the epidermis, and a deep layer, the dermis.

The epidermis, which is about 0.2 mm thick, consists of multiple layers, including the stratum corneum at the top. The stratum corneum, which is composed of stratum corneum, is the part that plays a "barrier function" on the skin that prevents the evaporation of water and protects it from viruses and bacteria.

The stratum corneum is a very thin layer of about 0.02 mm, but when the barrier function deteriorates due to external friction and other stimuli, it has the property of becoming thick and hard in an attempt to protect the skin from the stimuli.

This is a condition in which keratin, which normally peels off naturally as it gets older, becomes harder to peel off and accumulates .

The skin has pores that secrete sebum, but when old keratin accumulates, the pores become clogged and sebum tends to accumulate. The condition in which the pores are blocked by keratin and sebum is the initial condition of acne called "comedo".

Rash

The irritation caused by rubbing the mask can also cause a "rash" with symptoms such as redness, itchiness, pain, swelling and blisters .

Irritation is medically called "contact dermatitis" and is classified into "irritant contact dermatitis" and "allergic contact dermatitis", which is caused when the barrier function of the skin is reduced [* 2] ].

Irritation contact dermatitis is caused by unacceptable contact with irritants and can occur in anyone. Allergic contact dermatitis, on the other hand, develops when a person with a particular allergy comes into contact with the causative agent.

In addition, the cause of a rash caused by wearing a mask may be dust and pollen on the mask, as well as allergies to the material of the mask .

[* 2] References: Contact dermatitis-Recent trends-

Types of mask materials

There are many types of masks due to their different characteristics and shapes, but general materials are classified into the following three types.

  • Non-woven
  • Polyurethane, polyester
  • Natural fibers such as gauze, cotton and silk

If the material of the mask does not match the skin, symptoms of rash such as redness, eczema, and itching may appear, but it is said that natural fibers are less likely to cause rashes than chemical fibers.

Therefore, if you are worried about allergies to the material, you can also take measures against rough skin, such as "choose a mask made of natural materials" or "put gauze, cotton or a special sheet between the mask to prevent contact with chemical fibers". There is a possibility of becoming. If the mask is not a disposable type but a washable type, it must be thoroughly cleaned and cleaned before use.

Moisture in the mask

When wearing a mask, the inside of the mask is easily stuffy due to your breath . The temperature of exhalation is almost the same as the body temperature, which is around 36 ° C, and the humidity is close to 100%, so it is hot and humid.

This is an environment where acne is likely to occur .

When the secretion of sweat and sebum is promoted by the hot and humid condition, P. acnes that feeds on sebum grows .

Acne is thought to be one of the causes of acne, but it is an indigenous bacterium that is always present on healthy skin without acne. By producing organic compounds such as "propionic acid" and "fatty acids" and keeping the surface of the skin weakly acidic, it works to protect the skin from harmful bacteria and irritation. However, when keratin accumulates in the pores and sebum accumulates, P. acnes grows.

The grown P. acnes produces the enzyme "lipase" that breaks down sebum. The "free fatty acids" produced in the process stimulate the inside of the pores to cause inflammation, increasing the risk of acne with inflammation (acne that is more advanced than comedones) .

[*] References

In fact, the cause of acne has not yet been elucidated. Propionibacterium acnes, a gram-positive, high-GC-content (60%) bacterium that is thought to be one of the causes, is a resident bacterium that is widely distributed in healthy people. The lipid-degrading enzyme (lipase) produced and secreted by P. acnes hydrolyzes the lipids contained in sebum to become free fatty acids. This free fatty acid keeps the pH of the skin surface acidic and suppresses the growth of pathogens such as Staphylococcus aureus.

Changes in temperature and humidity when the mask is removed

When the mask is removed, the temperature and humidity around the skin change rapidly, making it easier for acne to occur.

It is said that the humidity that humans feel comfortable with is 40% to 60%, but the inside of the mask is hot and humid. Since air has the property of trying to reach the same temperature and humidity as the surroundings, when the mask is removed, the temperature difference and humidity difference of the air separated by the mask disappears, and the humidity of the air around the skin drops sharply. ..

Then, even the moisture of the skin will be deprived and it will be in a dry state . When the water content of the stratum corneum decreases due to drying and the barrier function deteriorates, the skin becomes more and more dry, creating a vicious cycle.

And when the skin dries, the secretion of sebum becomes active to supplement the moisture . When excess sebum is secreted, P. acnes, which feeds on sebum, grows and is prone to acne. Now that it is common to wear masks throughout the year, masks become stuffy not only in summer but also in winter.

Symptoms of rough skin caused by the mask and areas where the symptoms are likely to appear

Rough skin caused by a mask has the following symptoms.

  • Acne (pimples)
  • Redness
  • itch
  • eczema
  • Stiff

When severe, symptoms such as tingling, lumpiness, peeling, and sores may occur.

Symptoms tend to appear in areas where the rubber of the mask hits, around the nose, around the cheekbones, around the mouth, and on the face line, where they are likely to come into contact with the mask.

Precautions for rough skin measures and over-the-counter drugs

Take proper measures against UV rays

Even with a mask, UV rays reach the skin through the mask.

In addition to rubbing, UV irritation also affects skin turnover . Even on cloudy days, it is not possible to prevent the UV rays that are falling on you with a mask, so you must take proper measures against UV rays, such as applying sunscreen during the day.

Find the skin care method that suits you

After removing the mask, cleanse your skin with a face wash, moisturize your skin with a skin care product that suits you after washing your face, and find a makeup product that works for you, such as a powder that suppresses sebum. .. However, continued use of incorrect skin care methods, makeup methods, and skin care products that do not fit the skin can lead to worsening of symptoms.

If your symptoms do not improve after doing what you can, we recommend that you seek medical attention.

Use a mask that matches the material and size

If you are allergic to the material of the mask, you may be able to prevent it from getting worse by paying attention to the material. Also, choosing a size is important because if the mask size is too small, friction is likely to occur.

Be careful about your eating habits

Be aware of nutritional balance in your daily diet. Active intake of various vitamins also helps to keep the skin healthy .

Be careful of self-diagnosis

False self-diagnosis of symptoms may exacerbate symptoms.

For example, ointments (propet and petrolatum) and creams containing "steroids" that suppress redness, itchiness, and inflammation are often used to improve eczema , but if the infection is caused by acne, fungi, bacteria, or viruses, steroids are used. There is a risk of suppuration.

It is difficult to tell the difference between eczema and acne or bacterial infection, so if you are worried about the deterioration caused by using over-the-counter medicines, please consult a medical institution.

Cosmetology to improve rough skin and acne

In order to improve rough skin, it is necessary to arrange the turnover cycle, which is the metabolism of the skin, and prevent dryness.

The skin is layered from the outside to the epidermis and dermis, but it is in the epidermis that the skin cells are reborn. The epidermis is divided into the stratum corneum, the stratum granulosum, the stratum spinosum, and the basal layer, and the cells born in the lowest basal layer are gradually pushed upward. Eventually, it plays the role of a barrier in the stratum corneum, and when it finishes its role, it becomes dirt and peels off.

It is said that the turnover until cells are born in the basal layer and become dirt and peel off is said to be a cycle of about 28 days, but when the horny layer becomes thick due to friction, it is difficult to peel off and it is disturbed.

Therefore, cosmetological care that normalizes the turnover cycle normalizes the barrier function and reduces the chance of contact dermatitis . Also, when excess keratin is removed, it can prevent the overgrowth of P. acnes .

In addition, the barrier function means that the keratin retains water, which keeps the skin moisturized and avoids dryness .

Treatment to normalize the turnover cycle

Peeling treatment

Peeling treatments include chemical peeling, which applies chemicals such as salicylic acid and glycolic acid to the skin to dissolve and wipe off the accumulated old keratin, and a peeling machine that uses a stream of water to remove dirt and old keratin .

In both cases, by removing dirt and keratin accumulated on the surface of the skin, the cells of the stagnant skin are metabolized and the barrier function works normally.

Then, it can be expected that the moisture content of the skin will be maintained and protected from external stimuli, and that the texture will be smooth and smooth and healthy.

Peeling cost market price

Chemical peeling costs about 5,000 to 10,000 yen for the entire face, and 20,000 to 30,000 yen for the entire face if the peeling machine "Hydra Facial" is used.

Risks and side effects of peeling treatment

Risks and side effects of chemical peels may include redness, dryness, peeling, and temporary deterioration of acne.

Hydra facials have similar risks and side effects, but because the drug touches the skin for a very short time and moisturizes while removing dirt, the risks and side effects tend to be less likely to occur than chemical peels. I will.

In addition, it is necessary to moisturize the skin sufficiently after the treatment because the skin tends to dry after the treatment. / p>

Dermapen 4

Dermapen 4 is a pen-type medical device with 16 extra-fine needles. The vertical movement of the needle creates fine holes on the surface of the skin. Then, the cells of the dermis are activated in the process of repairing the needle hole by the action of the "natural healing power" that humans have. This will improve the disturbance of the turnover cycle of the epidermis above the dermis.

Dermapen 4 can be combined with various beauty essences as an option, and it is said that beauty essences containing growth factors are effective in activating skin cells .

By making a hole in the skin with a needle, the active ingredient can easily reach the depths, so you can expect a synergistic effect of the treatment by combining it with a beauty essence.

Dermapen 4 cost quote

It costs about 15,000 to 50,000 yen for the whole face treatment with Dermapen 4 alone, and about 10,000 to 100,000 yen will be added to the treatment with Dermapen 4 alone, depending on the beauty essence when adding an optional beauty essence. ..

Plasma treatment

Treatment that irradiates the skin with plasma energy is called plasma treatment. As the temperature rises, a substance changes into a solid, a liquid, or a gas, and the next state of the gas is plasma.

Since plasma does not react with pigments such as melanin pigments and water existing in the skin, it can deliver energy deep into the skin (dermis).

When the cells of the dermis become healthy, the cells of the epidermis that exist on the dermis are also activated, leading to a normal cycle of turnover. In addition, since plasma has a bactericidal action, it can be expected to be effective in improving acne.

Plasma treatment cost quotes

Neogen PSR is a machine that performs plasma treatment, but it costs about 20,000 to 45,000 yen for treatment on the entire face.

Risks and side effects of plasma treatment

Iontophoresis

Iontophoresis is a method in which a water-soluble beauty active ingredient penetrates deep into the skin by passing a weak electric current through the skin with an iontophoresis device. By selecting a beauty active ingredient that responds to skin problems, it leads to improvement of skin quality.

For example, iontophoresis of vitamin C and tranexamic acid can be expected to have the effect of normalizing the turnover cycle and suppressing inflammation of rough skin.

Iontophoresis cost market

The fee for iontophoresis varies depending on the beauty active ingredient to be infiltrated, but it is about 5,000 to 15,000 yen for each facial treatment.

Iontophoresis risk / side effects

It is said that there are almost no risks or side effects, but the active ingredient may cause redness, itchiness, rash, rash, etc. If it appears, it will be settled in a few days.

How to choose a medical institution to treat rough skin and acne

Rough skin and acne are common, so treatment at a medical institution may seem exaggerated. However, by receiving treatment, not only can you expect improvement of rough skin and acne, but you can also aim for healthy skin that is less likely to cause skin problems.

In addition, as acne worsens, it is more likely that it will remain as acne scars with pigmentation and irregularities, so it is important to receive treatment at an early stage .

Difference between cosmetic dermatology and general dermatology

In general dermatology, the purpose is to cure the symptoms, but in cosmetic dermatology, in addition to curing, the purpose is to maintain beautiful skin after that. Therefore, in addition to the treatment of rough skin and acne, it is possible to receive treatment aimed at improving the overall skin quality, such as improving elasticity, firmness, and dullness, after consulting with the skin problems that you are usually worried about. is.

On the other hand, in the case of so-called adult acne after the 20s, there are many cases where there is little improvement with medical insurance medicine . In addition, many adults with acne and rough skin are also concerned about age-related skin changes such as pore opening, age spots, and dullness, and beauty skin that can improve such age-related skin changes at the same time. It is recommended that you take care of yourself at your own expense.
