How to get rid of acne scars

"Although the inflammation of acne has subsided, the redness and unevenness of the skin do not disappear easily ...", "I went to a dermatologist, but the acne scars did not heal ...", I often worry.

Acne scars are a condition in which acne damages the skin and leaves it in some form as a scar. In some cases, it is difficult to remove acne scars cleanly, but it is faster to get rid of acne scars by treatment at a cosmetic dermatologist, rather than trying to get rid of acne scars by yourself, such as using over-the-counter medicines or using make-up until it disappears. Can be improved. It is also important to take proper acne care so as not to make acne scars.

If you want to get rid of acne scars, it's important to know the cause

There are several types of acne scars. If you want to get rid of acne scars, start by knowing the types and mechanisms of acne scars.

[1] Mechanism for acne scars

Acne scars are redness, pigmentation, dents, craters, etc. that remain after acne has healed. Inflammatory acne is accompanied by some acne scars. Mild acne can be cured cleanly without leaving any acne scars, but when acne causes severe inflammation, it damages the depths of the skin and leaves it as an indelible acne scar.

・ Mechanism of <redness> of acne scars

The most common acne scar is "redness of acne scars". Also called post-inflammatory erythema. It is a condition in which acne inflammation remains as a trace and becomes red. It is manifested by the inflammation of acne, which creates or dilates new capillaries.
If it is longitude, the reddish acne scars will gradually fade and disappear due to skin turnover. However, if the inflammation is severe and the deep part of the skin is damaged, it will be difficult to eliminate the redness over time. In this case, you will need treatment to get rid of acne scars at the clinic.

・ Mechanism of <pigmentation> of acne scars

"Pigmentation of acne scars" is also a common symptom. Inflammation caused by acne damages the skin, activates melanocytes and produces a large amount of melanin, and after the inflammation of acne has subsided, it appears as acne scars and remains as brown spot-like pigmentation. is. The deposition of pigment after inflammation is called "post-inflammatory hyperpigmentation".
Similar to the redness of acne scars, it usually gradually fades over half a year to several years with skin turnover, but depending on the degree of damage caused by inflammation, the color may not disappear and may remain forever.

You can use whitening care to lighten brown acne scars just like normal spots, but scars caused by severe acne cannot be easily removed without treatment at the clinic.

・ Mechanism of <dent / crater> of acne scars

Acne scars that are even more severe than redness and pigmentation are dents and craters on the surface of the skin. Depressions and craters are caused by acne inflammation that reaches the dermis of the skin and destroys it. In addition, crushing acne with your nails can also cause craters.
Acne scars that have become dents or craters cannot be removed by themselves, such as by natural healing or home care, and treatment at the clinic is required to cure them cleanly.

・ Mechanism of <lump / keloid> of acne scars

When acne-induced inflammation reaches the dermis, lumps may occur due to abnormal skin regeneration. The skin tries to repair the wound and overproduces collagen. This is also a severe acne scar and needs to be treated at the clinic to get rid of it.

Also, in rare cases, acne scars may rise red and keloids may occur. The cause is not clear, and it is thought that there is a strong factor due to constitution. It does not occur with mild acne, but is caused by acne that damages deep into the skin. It is easy to form around the lower jaw, decollete, shoulders, and scapula.

 

[2] Places where acne scars are likely to occur

Crater-type acne scars are more likely to occur on the temples, foreheads, and cheeks where the sebaceous glands are well developed. In addition, adult acne that occurs after becoming an adult is characterized by occurring on slightly dry areas such as the face line and easily becoming acne scars. Adult acne (pimples) often repeats inflamed red acne, and since skin metabolism is weaker than in puberty, damage accumulates and acne scars are more likely to occur.

[3] Characteristics of acne that become acne scars

Acne that tends to leave marks are "red acne" that is inflamed and swollen red, and "yellow acne" that is exacerbated by red acne and has pus.
"White acne" and "black acne" do not leave acne scars in most cases, so take care not to make them worse. In addition, there is also "purple acne" in which pus and blood collect deep in the pores. This is an even more severe acne than yellow acne, and there is a high probability that acne scars will remain. The symptoms are so severe that it can be quite difficult to get rid of the marks.

In order not to leave acne scars, it is important to cure the acne before it becomes inflamed, and even if it does occur, it is important to calm the inflammation at the earliest possible stage. Also, if you touch the acne unnecessarily to give it extra stimulation, or if you forcibly crush the acne with your fingers, it will easily become acne scars. Please note that you may go unknowingly.

If you have acne scars, talk to your doctor. A type of acne scar that cannot be erased by itself can be treated by a cosmetologist.

 

By type of acne! Measures to prevent acne scars

[1] Measures to avoid leaving traces of "red acne" and "yellow acne"

・ Acne scars caused by red and yellow acne

Red acne is especially prone to acne scars. Red acne is an inflamed acne in which P. acnes grows in the pores, causing inflammation and swelling red. As explained in the mechanism of acne scars, when inflammation occurs, "redness" remains on the skin for a while after the inflammation subsides. In some cases, it may become "pigmented" in brown.
If it is mild, the color will gradually fade over time, but if the inflammation is prolonged, the damage to the skin will be greater, and it will be easier to leave marks as strong redness and brown pigmentation. In addition, if red acne progresses further and becomes yellow acne (cystic acne) in which pus accumulates in the pores, there is an increased risk of becoming marks such as "dents" and "craters" that cannot be erased by oneself.

・ It is important to suppress inflammation at an early stage

The biggest point to prevent acne scars is to suppress inflammation as soon as possible. Cosmetological dermatology treatment is effective in quickly relieving inflammation of red acne. Ointments are common, but in severe cases, oral medications are also prescribed. In addition, red acne is often caused by hormonal imbalance, so Chinese herbs may be used to improve the constitution.
In order to quickly relieve inflammation, we recommend a combination of original external medicine and in-hospital treatment. Combined use of in-hospital treatments such as LED treatment and iontophoresis, which have a high anti-inflammatory effect on acne, can calm acne inflammation faster than treatment with ointment alone. Depending on the symptom, acne extruding that pushes out the sebum in the pores and acne injection that suppresses inflammation by injecting a special drug directly into the acne site are also effective.

Some people may find it cumbersome to go to a dermatologist with acne, but home care alone has its limits in getting rid of inflamed red acne. The most effective way to prevent acne scars is to go to the hospital and quickly control the inflammation so that it does not progress to severe acne, which is more likely to remain as a scar.

[2] Measures to prevent "white acne" from becoming acne scars

White acne is a condition in which sebum accumulates in the closed pores. If the symptoms subside at the stage of non-inflamed white acne, there will be no acne scars. When acne develops, it is important not to make it worse and to treat it promptly and appropriately.
White acne is not inflamed, so we do not use antibiotics like red acne. At the clinic, it is recommended that you use a special tool to extrude the sebum that has clogged the pores with acne extruding (face acne extruding / Menpo Asshutsu) or chemical peeling to remove the old keratin that has accumulated in the pores. .. If you crush acne yourself, you may get red acne due to germs, or you may have severe acne scars that are difficult to remove. Therefore, be sure to extrude acne at the hospital.

[3] Black acne

Black acne is a condition in which white acne progresses and the comedo that has clogged the pores turns black when it comes into contact with the air and oxidizes. Since it is not inflamed, it will not become acne scars if the symptoms subside at the stage of black acne.
If black acne occurs, it is important not to make it worse and to treat it quickly and appropriately. As with white acne, treatment at the clinic includes acne extruding (acne extruding / menpou asshutsu) and chemical peels.

Treatment to get rid of acne scars

So far, we have explained the mechanism of acne scars and the measures to prevent acne scars. From here, I will talk about how to erase the acne scars that have been made.

[1] If you want to get rid of acne scars, we recommend a cosmetology dermatologist.

Even if you want to get rid of acne scars, it is quite difficult to get rid of them with home care alone, and dermatological insurance does not cure acne scars. In that respect, since cosmetic dermatology is a free medical treatment, you can receive various acne scar treatments that are not limited to insurance coverage.
However, even with acne scar treatment in cosmetic dermatology, acne scars do not disappear completely with just one treatment, and multiple treatments are required. The appropriate treatment depends on the type and condition of the acne scar, so consult your doctor and ask them to suggest a treatment method that suits you.

[2] Cosmetic dermatology treatment method for acne scars (redness)

When you want to eliminate the redness of acne scars, we recommend treatment with a dye laser. By irradiating the affected area with a laser that has the property of being absorbed by the red pigment, the dilated capillaries are closed and the redness of the skin is reduced. Since it is a laser treatment, there is a downtime of several days immediately afterwards (a period during which redness and swelling remain), but a high therapeutic effect can be expected.

In addition to laser treatment, "LED treatment" that suppresses inflammation and promotes skin turnover, and "iontophoresis" that permeates components such as vitamin CE derivatives and tranexamic acid into the skin to soothe redness are also performed at the cosmetic dermatology department. I have. LED treatment and iontophoresis are easy treatments because there is no pain or postoperative downtime.

 

[3] Cosmetological dermatology treatment method for acne scars (pigmentation)

If you want to eliminate the pigmentation of acne scars, we recommend treatments such as "iontophoresis" and "mesofacial" (etroporation treatment), which thin melanin and introduce vitamin C derivatives that have a whitening effect deep into the skin. In addition, peeling treatment that promotes skin regeneration and "laser toning" that gradually discharges melanin pigment to the outside with a gentle power laser can also be expected to be effective in improving pigmentation of acne scars.

 

[4] Cosmetic dermatology treatment method for acne scars (dents / craters)

For dents and crater-type acne scars, "fractional laser treatment" that makes small scratches on the skin and promotes new skin regeneration is indicated. Depending on your symptoms, you may be able to make acne scars less noticeable with about 5 treatments. In addition, it is effective not only for acne scars but also for improving wrinkles and skin quality, so the impression of the entire skin changes completely. There is some downtime after the procedure due to the strong treatment that enhances the effect.

[5] Cosmetic dermatology treatment for acne scars (lumps and keloids)

If acne scars become lumpy, "fractional laser treatment" that promotes dermis regeneration and "acne injection" that injects a special drug directly into the lump are indicated. If you have become keloid, acne injection is also indicated.

[6] Differences between esthetic treatments and cosmetological dermatological treatments

Acne scar courses at beauty salons are also popular. It is easier to go to than a cosmetology dermatologist, and the price is relatively reasonable. However, you cannot use drugs or medical equipment because you cannot perform medical treatment at the beauty treatment salon.
"Iontophoresis" and "peeling" are common for skin redness care and pigmentation care performed in the acne scar course of beauty treatment salons, but there are limits to the types and concentrations of ingredients that can be introduced and the peeling agents that can be used. Therefore, it is not as effective as cosmetic dermatology. In addition, esthetic treatments cannot eliminate severe acne scars such as dents, craters, and lumps.

 

Things to watch out for in your daily routine to get rid of acne scars

Cosmetological dermatology treatment is effective for eliminating acne scars, but it can be further enhanced by incorporating self-care in daily life.

[1] Take proper measures against UV rays

Ultraviolet rays not only promote the production of melanin pigment, which is the cause of pigmentation, but also increase the risk of acne scars by advancing the deterioration of acne. If you have acne, apply sunscreen regardless of the season, and spend the summer with a sunscreen and a hat.
By taking proper measures against UV rays, you can prevent acne from getting worse and at the same time prevent acne scars. When choosing a sunscreen, choose an item that is as light on your skin as possible so as not to worsen the acne itself.

[2] Keep your skin moisturized with moisturizing care

Keep your skin moisturized with skin care.
When the skin is dry, the barrier function deteriorates, making the skin more susceptible to external stimuli such as ultraviolet rays. Where it has already been damaged by acne inflammation, it will also be damaged by the effects of dryness, which will delay the recovery of the skin. Dryness also causes disturbed skin turnover.

For moisturizing care, use a lotion with high moisturizing power, and don't forget to apply gel or milky lotion over it to supplement the oil. It is NG to use no oil to reduce the stickiness of the skin. Moisture escapes from the skin and it dries, reducing the barrier function.

[3] Adjust turnover with keratin care

Keratin care is the proper removal of dead skin cells that are no longer needed on the surface of the skin. Accumulation of old keratin disrupts the cycle of skin cell reincarnation called turnover, which is a factor that hinders the improvement of acne scars, especially pigmentation.
Since keratin care using scrubs and strong peels may cause extra irritation to the skin and worsen acne scars, choose a mild keratin care item such as a keratin beauty water that you just apply.

[4] Wash your face gently and be careful not to remove too much sebum.

People with acne tend to remove more sebum than necessary by washing their face. You also need a moderate amount of sebum to keep your skin healthy, so don't use facial cleansers that are too detergency or wash your face multiple times a day.
Also, when washing your face, it is important to lather a generous amount of facial cleanser and wash gently so as not to damage your skin.

[5] Do not give extra friction or irritation

Friction and irritation on the surface of the skin reduces the barrier function of the skin and promotes dryness and pigmentation. Be careful not to rub your face after washing your face, prevent acne scars from rubbing when wearing a mask, and do not irritate your skin as much as possible.

Also, if you are worried about acne scars, you tend to touch or scratch them with your hands, but be careful as it may worsen your skin condition.

[6] Incorporate whitening items well

It is also recommended to use items that contain whitening ingredients such as vitamin C derivatives and hydroquinone.
In particular, Vitamin C has a function of removing active oxygen to prevent the deterioration of acne and a function of helping the production of collagen and elastin, in addition to the whitening effect of suppressing the production of melanin. It also supports the treatment of unevenness with a laser. Since it is included in all cosmetic items, it may be easy to incorporate it into skin care.

[7] Supplement vitamins with a well-balanced diet

Let's take care of acne scars not only from the outside but also from the inside of the body with meals. There are many vitamin-rich foods in the home.
Lemons, strawberries, and red peppers contain vitamin C and have a whitening effect. We also recommend nuts and sesame seeds containing vitamin E, which has a blood circulation promoting effect, and liver and natto, which contain vitamin B to prevent acne. In addition, supplements are also recommended as they can easily supplement vitamins.

Be careful not to take too much fried foods, sweets, and carbohydrates that make acne worse.

summary

Acne scars cannot be easily erased once they are created. Redness and brown pigmentation may heal over time, but laser treatment at a cosmetological dermatologist is required to eliminate acne scars such as craters and lumps. Also, it takes a long time for redness and pigmentation to disappear, so if you want to get rid of the marks quickly, it is a good idea to have a cosmetology dermatologist.

Of course, it is most important to get proper acne treatment early so that no acne scars remain. Cure acne before it becomes inflamed, and if it does, use medicines to quickly relieve it.
