There are various treatments for acne scars , such as laser treatment and treatments using internal and external medicines, but Dermapen is one of the treatments that can be expected to improve acne scars . After being injured, a procedure called microneedling that focuses on the ability of humans to heal wounds, intentionally makes small holes in the skin to make scars and promotes skin regeneration , leading to improvement of acne scars. I will.
In recent years, Dermapen has become more popular as photos before and after the procedure are introduced on SNS as it can be expected to have beautiful skin, but treatment using Dermapen 4 can only be received at medical institutions in Japan . If you receive it at a non-medical institution such as an esthetic salon, you may be using a machine similar to Dermapen 4, which is different from the treatment of Dermapen 4. Recently, similar products of Dermapen have been sold on the Internet, and self-Dermapen for microneedling at home has also appeared.
The treatment effects and risks that can be obtained at medical institutions, non-medical institutions, and self-care facilities will vary greatly . Please check the correct information before the Dermapen 4 procedure so that you can improve the acne scars without failure in the Dermapen 4 procedure.

Dermapen 4 is a machine that makes holes in the skin to make scratches, promotes skin regeneration, and aims to improve pore opening, dented acne scars, fine wrinkles, etc. Dermapen is the name of the machine used for micro-kneading, and is a product developed by Dermapen World, which is headquartered in Australia. The first Dermapen was sold as a product in 2010, and the latest Dermapen 4 was sold in 2018.
As the name suggests, Dermapen 4 has a pen shape, and a needle that is thinner than the hair is attached to the tip, and the needle is moved up and down to evenly make holes in the skin .
The needle is a removable cartridge type for hygienic use, and the used needle cartridge can be discarded or replaced after one person's treatment. There are 16 needles in the needle cartridge, and the treatment is performed by sliding the pen on the skin to make fine holes evenly in the skin. By making fine holes in the skin, the healing power and regeneration ability of the body are activated, and the effect of producing collagen and elastin necessary for skin regeneration can be expected.
With Dermapen 4, the depth of the hole to be drilled in the skin can be set to 0.2 mm to 3.0 mm, the thin skin part is shallow, the thick skin part is deep, the part with dented acne scars is deep, etc. Adjust the needle depth according to the symptom.
Dermapen 4 is mainly applied to the face, neck and hands, but it is prohibited to apply it to the orbit (the hollow of the skull where the eyeball fits) .
|Part||Thin skin||Thick skin|
|Between the eyebrows||0.3mm-0.5mm||0.5mm|
|Around the lips||0.3mm-0.8mm||0.5mm-0.8mm|
|Scar treatment (deep acne scars, etc.)||3.0mm||3.0mm|
|Stretch mark (cracked meat)||1.5mm-2.0mm||1.5mm-3.0mm|
|Scars (such as shallow acne scars)||1.0mm-1.2mm||1.2mm-1.5mm|
There are five types of acne scars, of which Dermapen 4 can be expected to improve acne scars called atrophic scars , which cause the skin to become dented .
|Types of acne scars||Acne scars|
|Post-inflammatory erythema||The area where the acne was present turned red even after the acne inflammation had subsided.|
|Post-inflammatory hyperpigmentation (enshogoshikisochinchaku)||A state in which the area where the acne was present is pigmented like a spot after the inflammation of the acne has subsided.|
|Atrophic scar (Ishukuseihankon)||A condition in which the acne area is damaged by inflammation up to the dermis layer, and the skin is dented after the acne has healed.|
|Hypertrophic scar (Hikoseihankon)||After the acne has healed, the area where the acne was located has risen red.|
|keloid||A state in which the area that is red and raised is wider than the hypertrophic scar.|
Atrophic scars are sometimes referred to as crater-like acne scars. The skin has three layers: epidermis, dermis, and subcutaneous tissue, and the dermis layer will not be damaged unless the acne inflammation is so strong.
However, when acne becomes more inflamed, it damages the dermis layer, making the dermis layer thinner than normal skin, resulting in atrophic scarring. By stimulating the dermis layer with the needle of Dermapen 4 to promote the production of collagen and elastin and guide the regeneration of the dermis layer, improvement of skin dents can be expected.
In addition to atrophic scars on acne scars, post-hypertrophic scars that remain reddish (enshogokouhan), post-inflammatory pigmentation that becomes pigmented and becomes like spots (enshogoshiki sochinchaku), Hypertrophic scars where the area where acne was present rises red ・ There are keloids where the area that rises red than the hypertrophic scars spreads.
Improvements can be aimed at by internal and external medicine treatment, peeling treatment that promotes turnover, which is the metabolism of the skin, IPL (light) treatment, laser treatment, and injection treatment.
In the treatment of Dermapen 4, it is said that by adding a drug as an option and applying the drug to the skin with fine needle holes , the beauty ingredients can penetrate and the effect can be promoted efficiently . There are various options that can be expected to have a synergistic effect, such as normalizing the turnover cycle and supplementing the elasticity of the skin, but we have introduced two beauty essences that can be expected to be effective in improving acne scars. I will.
A beauty essence based on human adipose stem cell-derived exosomes, which has obtained a US patent for whitening, wrinkle prevention, and skin regeneration .
Exosomes are important substances that transmit information between about 200 types of cells in the body. They secrete growth factors and cytokines to the cells that transmit information, and have the effect of changing to hepatocytes and nerve cells.
Growth factors and cytokines secreted by exosomes have the effect of promoting cell proliferation, differentiation, and maturation, and can be expected to be effective in the regeneration of skin tissue . When used for atrophic scars caused by a decrease in the dermis layer of the skin, it promotes the regeneration of the dermis layer and leads to improvement of atrophic scars.
A beauty essence whose main component is dried amniotic membrane derived from humans . The amniotic membrane is a thin membrane that covers the innermost layer of the uterus and placenta, and is composed of the amniotic epithelial tissue, the basement membrane below it, and the collagen-rich amniotic membrane cell tissue. Since amniotic membrane cell tissue does not contain blood components that cause rejection when transplanted, rejection is unlikely to occur even when transplanted to another person, and in recent years it is said that there is a possibility of cell transplantation.
AmnioGenix is a dry, cell-free amniotic membrane with minimal processing of human amniotic membrane, which contains multiple extracellular matrix proteins, growth factors, and cytokines present in the amniotic membrane tissue. Extracellular matrix proteins have the effect of adhering cells to each other, and growth factors and cytokines have the effect of promoting cell proliferation, differentiation, and maturation. It also contains specific proteins that cause migratory effects that carry stem cells, which have the ability to regenerate and replenish lost cells, between cells.
By promoting the regeneration of cells in the reduced dermis layer by the action of extracellular matrix proteins, growth factors, cytokines, and specific proteins, it can be expected to be effective in improving atrophic scarring.
Peeling is a procedure in which the drug is applied directly to the skin and the skin is peeled off to promote skin regeneration. Peeling alone or Dermapen 4 alone can be expected to improve acne scars on atrophic scars, but the combined use of Dermapen 4 and peeling increases the satisfaction level of improving acne scars on atrophic scars compared to a single treatment. There is clinical data called.
Dermapen 4 is painful because it involves piercing the skin with a fine needle. The deeper the needle, the stronger the pain, but in most cases, an anesthetic cream is applied to relieve the pain.
Symptoms such as redness and tingling after the treatment. Basically, it usually takes about 24 to 36 hours to settle down. In addition, it may cause peeling, and if peeled, it takes about a week to settle down.
Normal face washing and makeup will be possible after about 12 hours of treatment. Dermapen foundation with excellent cooling and moisturizing properties can be used immediately after treatment.
|Dermapen 4 is an unapproved device of the Ministry of Health, Labor and Welfare.|
| Medical device acquisition route: The acquisition route is individual import from the manufacturer by the doctor of each medical institution.|
Drugs that should be noted in personal imports (Ministry of Health, Labor and Welfare page)
Approval in Japan: There is no medical device that has the same performance and effect as Dermapen 4 and has been approved in Japan.
| Information on safety in other countries: According to Dermapen World, the developer of Dermapen 4, it has also obtained the CE mark that certifies safety and quality in Europe [* 1]. Common side effects reported in other countries include:|
Redness, bleeding, internal bleeding, bruising, infection, dryness, stiffness at the treatment site
Dermapen 4 is often recommended to be treated multiple times depending on the degree of dents in the acne scars, and depending on the depth of puncture , treatment is recommended once a month, about 3 to 5 times . If the dent is shallow, it is said that even one treatment can be expected to be effective, so if you are concerned about the number of treatments, please check with your doctor.
Dermapen 4 is a device not approved by the Ministry of Health, Labor and Welfare, so it is not covered by insurance. When receiving acne scar treatment on Dermapen 4, the market price is 20,000 to 30,000 yen for the entire face treatment with Dermapen 4 alone . If you add the option menu of ASCE plus SRLV-S or Amnio Genix, the charge will be added accordingly.
If the price is higher than the market price, the treatment may come with an anesthetic cream, serum, sedation pack, etc., so please check with your medical institution for details.
Since the popularity of Dermapen has risen, machines that allow you to micro-need yourself have appeared. Doing microneedling by yourself is called self-dermapen, and videos etc. are uploaded on SNS.
Since Dermapen 4 can only be used at medical institutions, it is similar to Dermapen 4, but machines capable of microneedling can also be purchased online. Some people buy a similar product of Dermapen 4 from online shopping and perform the treatment by themselves because it is cheaper and easier than going to a medical institution.
However, no matter how small it is, since it is a procedure to make a hole in the skin, hygiene management such as disinfection is required before the procedure, and if sedation care is not taken properly after the procedure, bacterial infection and inflammation will occur and scars will remain. There is a possibility.
If you are going to be treated at a medical institution, you should see a doctor to check if you have a good skin quality by performing Dermapen 4, but if you use self-dermapen, you cannot check the skin quality and you have an allergic reaction. There are concerns about the risk of getting rid of the skin and purging the wound .
Self-dermapen in areas without medical knowledge or hygiene is not recommended as it carries a great risk.

Internal and external medicines are often used in the treatment of acne, and it is said that they can be expected to be effective for all types of acne scars .
There are a wide variety of medicines, and each ingredient has different effects such as antibacterial, bactericidal, and exfoliation of keratin. By using it according to the symptoms of acne, it suppresses the inflammation of acne and eliminates the clogging of pores. You can expect effects such as
It can be expected to be effective for acne scars, but it is said that the effect is mild and the treatment period is several years . It will be covered by insurance.
Of the five types of acne scars, this is an uninsured procedure that can be expected to be effective against atrophic scars. The cause of atrophic scars is that the area that was acne is inflamed to the dermis layer, and as the acne heals, the dermis layer is not completely repaired and the dermis layer becomes thinner than normal skin.
By injecting hyaluronic acid or collagen into the area where the dermis layer has become thinner and more dented than normal skin, the thinned dermis layer can be made physically close to normal skin, resulting in atrophy. Leads to improvement of sexual scarring.
It is a treatment that can be expected to be effective for post-inflammatory hyperpigmentation in a state of pigmentation and stains, post-inflammatory erythema in a state where redness remains, and atrophic scars that are acne scars in a state where the skin is dented.
Post-inflammatory hyperpigmentation and post-inflammatory erythema acne scars are caused by melanin and hemoglobin. The wavelength of the laser is absorbed by melanin and hemoglobin, which are the causes of acne scars, and becomes heat energy, which destroys melanin and hemoglobin , leading to improvement of acne scars .
In addition, for acne scars of atrophic scars, the dermis layer is irradiated with a laser to generate heat energy, which promotes the production of collagen and the reconstruction of skin tissue. Improvement can be expected by flattening the dents on the surface.
Redness, burning, and tingling may occur after the treatment, but it is said that it will subside in about 2 to 3 days. Makeup after treatment is possible, but some treatments cannot be done for 24 hours depending on the type of laser. The treatment is not covered by insurance, so you will be responsible for all treatment costs.
It is a treatment that can be expected to be effective for post-inflammatory hyperpigmentation and post-inflammatory erythema with redness remaining after pigmentation and becoming like spots.
The causes of post-inflammatory hyperpigmentation and post-inflammatory erythema are melanin and hemoglobin. The wavelength of IPL (light) is absorbed by melanin and hemoglobin and becomes heat energy, which destroys melanin and hemoglobin and leads to improvement of acne scars .
Since the wavelength output is relatively weak and there is almost no downtime, you can make up immediately after the procedure . However, since the effect of one treatment is mild, multiple treatments are recommended. The treatment is not covered by insurance.
It is an insurance-covered treatment that can be expected to be effective for hypertrophic scars and keloid acne scars.
When acne becomes more inflamed, it damages the dermis and destroys skin cells. The cells destroyed during the healing process of acne are excreted from the body and new skin cells are created. Hypertrophic scars and keloids cause the skin to swell as a result of being out of control when new skin cells are created and creating too many cells.
There are clinical data showing improvement in hypertrophic scars and keloids by injecting steroids into the raised area. The mechanism by which steroid injections act on hypertrophic scars and keloids is unknown, but numerous clinical data suggest that steroid injections can be expected to improve hypertrophic scars and keloids.
Dermapen World, the developer of Dermapen, has a Dermapen 4 training doctor, who provides Dermapen 4 treatment training to various medical institutions and doctors. If you are a doctor who received a lecture directly from the training doctor , such as the order and pressure to slide the Dermapen 4 on the skin, you can receive the treatment with confidence.
In addition, because it is a procedure to make holes in the skin, there is a risk of bacterial infection if hygiene is not managed. To prevent infection, it is safe to choose a medical institution that you can trust in hygiene management, such as wearing a body cover called a DP sleeve .
