Acne Treatment | Isotretinoin, Topical and Oral Medications

Acne is not just a teenage problem; "adult acne" in people in their 20s and older is a very common condition, with more than half of women reportedly experiencing it. At Mona Clinic, we offer a wide range of treatment options to suit the severity of your symptoms, from standard treatments such as topical medications and oral antibiotics, to isotretinoin, a self-pay treatment for moderate to severe acne that has not responded to treatment at other clinics.

  • ✓We offer treatment options tailored to symptoms, from mild to very severe (e.g., topical medications, oral antibiotics, low-dose birth control pills, Kampo medicine).
  • ✓For moderate to severe acne that has not responded to antibiotic treatment covered by health insurance, isotretinoin, available through private clinics, is also an option.
  • ✓Because acne scars (atrophic scars) are more difficult to treat, early intervention before scarring occurs is crucial.
  • ✓Online consultations available for prescription of topical and oral medications, including isotretinoin, with fewer clinic visits

What is acne (acne vulgaris)?

Acne (acne vulgaris) is a chronic skin condition caused by clogged pores with sebum, proliferation of acne bacteria, and inflammation. Recent advances in acne treatment mean that many people can aim for symptom improvement with appropriate topical and oral treatments (individual results may vary).

Self-care and over-the-counter drugs have limitations

There are many cases where acne worsens due to excessive face washing, insufficient moisturizing, or ineffective over-the-counter drugs. Prescription drugs (such as adapalene and benzoyl peroxide) can be used under a doctor's supervision for acne that is difficult to treat with over-the-counter drugs, and appropriate treatment can lead to improvement (individual results may vary).

Mechanism of acne formation

Acne occurs when the following four factors overlap:

  • Excessive sebum secretion (hormones, stress, genetics)
  • Clogged pores (keratinization abnormalities block pores)
  • Proliferation of P. acnes (proliferates in anaerobic environments, feeding on sebum)
  • Inflammation (immune response to P. acnes)

Types and stages of acne progression

Stage Name Appearance Inflammation
1 Microcomedone Invisible initial stage None
2 Whitehead (closed comedone) White to skin-colored small papule None
3 Blackhead (open comedone) Black center with an open pore None
4 Red pimple (papule) Red and raised, accompanied by pain Present
5 Pustule Has a yellowish-white pus at the tip Present (strong)
6 Cyst/Nodule Large, deep red swelling, high risk of scarring Present (deep)

The ideal time for treatment is at the "comedone (whitehead/blackhead)" stage, before inflammation occurs. As acne progresses to red pimples, the risk of scarring increases, so consider treatment appropriate for your symptoms as soon as you notice small pimples.

Acne severity classification and overall treatment approach

Acne treatment options vary depending on the severity. Let's first organize the overall picture.

Severity Criteria (inflammatory lesions on one side of the face) Main Treatment
Mild 5 or fewer Mainly topical agents
Moderate 6 to 20 Topical + oral antibiotics
Severe 21 to 50 Topical + oral + isotretinoin considered
Very Severe 51 or more, or accompanied by cysts/nodules and scarring forming Isotretinoin, referral to a specialized institution

You can start treatment that matches your stage.

Treatment Options

Topical medications (daily basic treatment)

Drug Features/Actions
Adapalene (Differin) A retinoid that unclogs pores. Effective from the comedone stage.
Benzoyl peroxide (Bepo) Antiseptic and keratolytic action. Effective for inflammatory acne. No resistance.
Adapalene + Benzoyl peroxide (Epiduo) Combined drug. Both effects in one product.
Benzoyl peroxide + Clindamycin (Duac) Anti-inflammatory/antiseptic + antibiotic.
Clindamycin (Dalacin T Gel) Topical antibiotic. For inflammatory acne.
Nadifloxacin (Aquacut) Topical antibiotic.

Adapalene and benzoyl peroxide can cause redness, peeling, and dryness in the first 1-2 weeks. This usually improves within about 2 weeks as the skin adjusts. The key is to start with a small amount applied once a night, while moisturizing thoroughly.

Oral Medications

Drug Usage Scenario
Vibramycin (doxycycline) Moderate inflammatory acne. 2-3 months.
Minomycin (minocycline) Alternative. Beware of pigmentation as a side effect.
Roxithromycin Macrolide. When tetracycline is contraindicated.
Tranexamic acid Prevention of post-inflammatory hyperpigmentation.
Herbal medicine (Jumihaidokuto, Seijobofuto, Keishibukuryogan) Constitutional improvement. Supplementary.
Low-dose birth control pills (LEP/OC) Effective for adult acne related to menstruation.
Isotretinoin (private treatment / unapproved in Japan) For severe/intractable cases (details below).

Long-term use of antibiotics carries a risk of antibiotic resistance, so use for a maximum of 3 months is generally recommended. Combining them with topical medications (especially benzoyl peroxide) can help prevent resistance.

Options for severe and intractable cases: Isotretinoin

For moderate to severe acne that shows insufficient improvement with topical medications or oral antibiotics, or extensive nodular acne with a high risk of scarring, we offer isotretinoin as a private treatment. Isotretinoin is an unapproved drug for acne treatment in Japan and is not covered by insurance. At our clinic, under the responsibility of the doctor, we will provide a thorough explanation of its contents, effectiveness, and serious risks (especially teratogenicity) before offering it as a self-pay treatment. Effects and side effects vary from person to person.

What is Isotretinoin?

Isotretinoin works by suppressing sebum production and shrinking the size of sebaceous glands. It is also believed to be effective for moderate to severe acne due to its ability to normalize keratinization and its anti-inflammatory effects. It has been used as a standard treatment for severe acne in many countries, including the US and Europe, since the 1980s.

Who is recommended to use it?

  • Individuals with extensive nodular acne (to minimize scarring)
  • Individuals suffering from moderate to severe acne
  • Individuals whose acne treatment with antibiotics covered by insurance has been ineffective
  • Individuals with excessively oily skin
  • Individuals experiencing mental or physical discomfort due to acne

Who cannot use it or requires careful consideration?

  • Those who are pregnant or may become pregnant
  • Those planning conception (including men) or who are breastfeeding
  • Those with allergies to this drug or vitamin A
  • Those with severe liver or kidney dysfunction
  • Those with high triglycerides, those undergoing treatment for dyslipidemia, or those with a history of pancreatitis
  • Those currently taking tetracycline-based antibiotics (doxycycline, minocycline, etc.)
  • Those with a history of mental illness such as depression (will be carefully evaluated)
  • Those with a history of inflammatory bowel disease (Crohn's disease, ulcerative colitis)
  • Those scheduled for major surgery
  • As per our clinic's policy, individuals under 18 or over 70 years old

Pre-treatment and during-treatment examinations

Isotretinoin can affect triglyceride levels and liver function, so blood tests will be conducted before and during treatment. Pregnancy tests will also be performed for those who may be pregnant. Information on testing methods will be provided during your consultation.

Important considerations when using

Isotretinoin is teratogenic (there is a risk of birth defects if taken during pregnancy). It should never be used by pregnant women or those who may become pregnant during treatment.

  • Strict contraception must be practiced for at least one month before starting, during treatment, and for one month after treatment.
  • It is recommended to start taking the medication on the 2nd or 3rd day of a normal menstrual cycle.
  • Avoid taking supplements containing vitamin A (as their combined effects can lead to stronger side effects).
  • Limit alcohol consumption during treatment as it can increase triglycerides.
  • About 10-20% of individuals may experience a temporary worsening of acne at the beginning of treatment, but it usually improves within about one month.
  • During and after treatment, discomfort with contact lenses may increase due to dry mucous membranes.
  • The skin becomes thinner and more susceptible to injury, so avoid waxing, strong chemical peels, and laser treatments during treatment.
  • Do not donate blood during treatment and for one month after discontinuation.
  • Symptoms such as depression, psychiatric symptoms, and rarely suicidal ideation have been reported (the mechanism of action is unclear). If you experience changes in mood, seek medical attention immediately.

Avoid co-administration with tetracycline antibiotics

Concomitant use of isotretinoin and tetracycline antibiotics (doxycycline = Vibramycin, minocycline = Minomycin, etc.) is known to increase the risk of intracranial hypertension (pseudotumor cerebri). If you are prescribed antibiotics by another clinic, please be sure to inform us.

The following symptoms are early signs of intracranial hypertension. If they appear, stop taking the medication and contact us immediately for a consultation.

  • Severe or persistent headache
  • Nausea/vomiting
  • Blurred vision, visual field abnormalities

Main side effects

Side effects are dose-dependent and can sometimes be reduced by lowering the dose (excluding teratogenicity).

  • Teratogenicity
  • Temporary worsening of acne in the initial stage of treatment (approx. 10-20%)
  • Dryness or dermatitis of the lips and face, dry nose and nosebleeds, dry eyes, light sensitivity (protect with lip balm, moisturizer, artificial tears, sunscreen)
  • Temporary hair loss, reduced night vision, muscle and joint pain
  • Increase in triglyceride levels and liver function values (confirmed by blood test)
  • Potential for pancreatitis due to high triglycerides
  • Intracranial hypertension (see above)
  • Depressive symptoms, suicidal ideation
  • Worsening of inflammatory bowel disease, diarrhea

Dosage目安

*The dosage will be determined individually by the doctor, so please consult us via official LINE. The following is a general guideline:

  • Initial: 0.5-1mg per kg of body weight, divided into two doses per day (maximum 2mg per kg of body weight).
  • Maintenance: 0.5-2mg per kg of body weight, divided into two doses per day. Treatment duration is 16-20 weeks (may be terminated earlier if the number of nodules decreases by 70%).
  • Cumulative dose is considered important, with a cumulative dose of 120mg/kg or more associated with better long-term remission (achieved with 1mg/kg of body weight in approximately 4 months).
  • If re-treatment is necessary, it is determined at least 8 weeks after the previous treatment ends (because improvement can continue even after discontinuation).

How effects manifest

Timeframe Estimated Progress
Month 1 Dryness begins. Acne temporarily worsens in approximately 10-20% of people.
Months 2-3 Sebum decreases, and new acne becomes less likely to form.
Months 4-5 (end of treatment) Inflammatory acne is often significantly reduced.
After treatment ends Improvement may continue for several months after discontinuing the medication.

Precautions regarding unapproved pharmaceuticals, etc. (Isotretinoin)

  • Unapproved drug: Isotretinoin is an unapproved drug in Japan for the treatment of acne.
  • Method of acquisition: The physician imports the drug after completing the necessary procedures for personal import (obtaining a Yakkan Shoumei from the Ministry of Health, Labour and Welfare).
  • Availability of approved domestic drugs: Approved acne treatments in Japan include adapalene, benzoyl peroxide, topical antibiotics, and oral antibiotics. There are no domestically approved oral medications with the same active ingredient.
  • Information on safety, etc., in other countries: Isotretinoin is approved as a treatment for severe acne in many countries, including the United States and Europe, and has been in use since the 1980s. However, due to its strong teratogenicity, it is managed under strict pregnancy management programs in various countries, and reports of depression, suicidal ideation, intracranial hypertension, and inflammatory bowel disease have been noted.
  • Health damage relief system: Health damage caused by the use of unapproved drugs is not covered by the Pharmaceutical Side Effect Relief System.
  • Cost/Effectiveness: Since this is an out-of-pocket treatment, health insurance does not apply, and you are responsible for the full cost. The degree of effectiveness varies from person to person.

Characteristics and Causes of Adult Acne

Adult acne, which occurs after the age of 20, has different characteristics than adolescent acne.

Characteristics

  • Commonly found around the jaw, mouth, and jawline (U-zone)
  • Difficult to cure and prone to recurrence
  • Often worsens before menstruation
  • Worsens with stress, lack of sleep, and an unbalanced diet
  • Involves hormonal balance (PCOS, stress-related)

Aggravating Factors

  • Hormonal imbalances (menstruation, pregnancy, changes in birth control pills, etc.)
  • Stress and lack of sleep
  • Excessive intake of high-GI foods and dairy products
  • Irritation from cosmetics and skincare products
  • Dry skin (excessive washing, insufficient moisturizing)
  • Humidity and friction from masks (maskne)
  • Drug-induced (steroids, lithium, etc.)

For those whose acne consistently worsens before menstruation, low-dose birth control pills may lead to an improvement in acne. Please consult us during your examination.

Addressing Acne Scars

Acne scars are broadly divided into three types, each requiring a different treatment approach.

Type Appearance Main Treatment
Post-inflammatory hyperpigmentation (PIH) Brown marks. Improve over time. Oral tranexamic acid, topical hydroquinone, sunscreen. Naturally subsides in several months to 1 year.
Post-inflammatory erythema Red marks Naturally subsides in several months. Sunscreen.
Scars (crater) Unevenness/deep marks Fractional laser/dermaroller (specialized clinics/self-pay)

Once crater-like scars form, they are difficult to treat, so the best prevention is to treat the acne early to avoid scarring. Begin treatment at the red acne stage.

Basic Correct Skincare

Face Washing

  • Wash twice a day (morning and night) gently, using plenty of lather created with a foaming net.
  • Rinse thoroughly with lukewarm water.
  • Do not scrub or wash too frequently (this can lead to excessive sebum secretion).
  • After washing, gently pat your face dry with a towel.

Moisturizing

  • Moisturizing is essential even for acne-prone skin (dryness can actually increase sebum production).
  • Choose non-comedogenic products that are low in oil and high in moisture.
  • Use lotions and emulsions containing ceramides and hyaluronic acid.
  • Avoid oil-based products as they can clog pores.

Sunscreen

  • Sunscreen is essential, especially during acne treatment, as UV rays worsen hyperpigmentation.
  • Choose non-comedogenic, low-oil formulas.
  • Use SPF 30 or higher and PA++ or higher daily.

Acne Prevention through Lifestyle Habits

Diet

  • Limit high-GI foods (white rice, bread, sugar).
  • Avoid excessive intake of dairy products (especially skim milk).
  • Eat a balanced diet of vegetables, fish, soybeans, and fermented foods.
  • Focus on B vitamins, zinc, and dietary fiber.
  • Drink over 1.5 liters of water daily.

There is no established evidence that chocolate or fried foods directly cause acne. Rather, high-GI foods (foods that rapidly raise blood sugar) are considered to have a higher correlation. Extreme dietary restrictions are not necessary, but limit refined sugars and sugary drinks.

Lifestyle Habits

  • Sleep 7 hours or more, avoiding staying up late if possible.
  • Promote metabolism with moderate exercise.
  • Manage stress (yoga, deep breathing, hobbies).
  • Wash pillowcases and towels frequently.
  • Keep hair away from your face.

Actions to Avoid that Worsen Acne

  • Popping pimples (spreads inflammation, causes scarring)
  • Touching or picking with fingernails
  • Washing face multiple times a day
  • Using alcohol-based disinfectants on the face
  • Daily use of strong scrubs or peels
  • Neglecting to moisturize
  • Trying multiple over-the-counter medications or supplements
  • Applying topical steroids to acne (worsens it)

Frequently Asked Questions

Q. How long does it take for acne treatment to show results?
A. For topical medications, it often takes 2-4 weeks for redness and peeling to subside, with visible improvement appearing over 2-3 months. Oral antibiotics typically show effects on inflammatory acne within 2-4 weeks. Isotretinoin may cause a temporary worsening in the initial stages, but significant improvement is generally seen around 3 months. Individual results may vary.
Q. Is isotretinoin an approved drug in Japan?
A. No. Isotretinoin is not approved in Japan for acne treatment. We provide it as an imported drug, based on a doctor's discretion, through out-of-pocket treatment. Health insurance does not apply, and it is not covered by the medical adverse reaction relief system as it is an unapproved drug. However, it has been widely used overseas for severe acne treatment since the 1980s.
Q. I'm concerned about the impact on pregnancy.
A. Isotretinoin has strong teratogenic effects and must not be taken during pregnancy. If there is any possibility of pregnancy, reliable contraception is required for one month before starting, during treatment, and for one month after stopping treatment. We cannot prescribe to those planning to conceive (including men). Please also refrain from donating blood during treatment and for one month after completion.
Q. Can I take it with vibramycin or minocycline?
A. Please avoid concomitant use. Taking isotretinoin with tetracycline antibiotics (doxycycline, minocycline) increases the risk of intracranial hypertension (pseudotumor cerebri), which involves elevated intracranial pressure. If you experience severe headache, nausea/vomiting, or vision disturbances, stop taking the medication and seek immediate medical attention.
Q. Is a blood test necessary during treatment?
A. Yes, it is necessary. Isotretinoin can affect triglyceride and liver function levels, so these are checked with blood tests before and during treatment. For those who may be pregnant, a pregnancy test is also conducted. We will guide you through the testing process during your consultation.
Q. I heard that acne gets worse at first.
A. With isotretinoin, about 10-20% of people may experience a temporary worsening of acne at the beginning of treatment. This usually improves within about a month. If you stop treatment on your own during this period, you may not achieve the desired effect, so please consult us if you are struggling.
Q. Are there any lifestyle precautions to take during treatment?
A. Severe dryness of the lips, nose, and eyes can occur, so it's good to have lip balm, moisturizers, and artificial tears ready. You will become more sensitive to sunlight, so sunscreen is essential. Alcohol consumption should be limited as it can raise triglycerides, and avoid supplements containing vitamin A. Waxing, strong peels, and laser treatments should be avoided during treatment as the skin is more prone to injury.
Q. Can acne scars be cured?
A. Brown hyperpigmentation and redness often fade over several months to a year with sunscreen, topical treatments, and oral medications. However, crater-like depressed scars are difficult to improve with oral and topical treatments alone and may require procedures like lasers. The best prevention for scarring is to start treatment at the red acne stage.

Frequently Asked Questions

Q Are over-the-counter drugs enough? How do they differ from dermatological prescription drugs?
A

While mild acne (a few whiteheads) may improve with over-the-counter medications, OTC treatments have limitations for recurring red or pustular acne. Prescription medications like adapalene and benzoyl peroxide offer a higher efficacy not found in OTC options. Early treatment is recommended to prevent acne scarring.

Q I applied the medication and developed redness and peeling. Is this normal?
A

When you first start using adapalene or benzoyl peroxide, you may experience dryness, redness, or peeling during the first 2 to 4 weeks. This is a sign that the medication is working, and in most cases, these symptoms will improve as you continue to use it. You can alleviate these symptoms by using a moisturizer in conjunction with the medication and starting with a small amount. If your symptoms are severe, or if you experience pain or swelling, discontinue use and consult a medical professional.

Q How long does it take for acne to heal?
A

It typically takes 2-3 months to see the effects. This is because improvement occurs after several cycles of skin cell turnover (approximately 28 days). It is important to continue treatment patiently, and to prevent recurrence by continuing maintenance therapy even after improvement.

Q Do I have to keep taking antibiotics indefinitely?
A

Antibiotics should fundamentally be used only for the necessary duration, considering the risk of resistant bacteria. Do not take them for extended periods on your own judgment; please follow the prescribed dosage, administration, and duration.

Q Can acne scars be cured?
A

Redness and hyperpigmentation can become less noticeable over time. However, indented acne scars may not improve naturally, so it is important to treat them appropriately from an early stage to prevent them from remaining.

Q Is contraception necessary while taking isotretinoin?
A

Yes. Isotretinoin is teratogenic, so it cannot be used by pregnant women or those who may become pregnant during treatment. Please ensure strict contraception for at least one month before starting medication, during medication, and for one month after finishing medication.

Q Can I get acne medication prescribed online?
A

Yes. Mona offers online medical consultations for acne treatments. After purchasing your desired medication, you will undergo a medical questionnaire and a video consultation with a doctor. If the doctor determines it is appropriate to prescribe the medication, it will be prescribed and delivered to you.
