What Is Epiduo (Epiduo Gel)? An Acne Treatment with Two Active Ingredients

Epiduo (Epiduo Gel) is an acne treatment medication containing two active ingredients: adapalene and benzoyl peroxide.

Each ingredient targets a different cause of acne, working together to help address breakouts.

In addition, among acne treatment medications, Bepio and Differin are well known, and Epiduo is a combination product that brings both together.

While Epiduo may offer the benefits of both medications, treatment may begin with Bepio or Differin alone to assess how your skin responds before progressing to the combination product.

What Causes Acne? How Acne Develops

Acne develops due to three main factors:

  • Increased sebum production, often driven by androgens and other hormonal factors
  • Clogged pores caused by a buildup of dead skin cells
  • Proliferation of acne-causing bacteria (C. acnes) inside the pore

Acne originates from clogged pores caused by dead skin cell buildup. As C. acnes multiplies inside the blocked pore, the acne worsens.

A clogged pore is called a whitehead; one oxidized by sebum becomes a blackhead; one where C. acnes has proliferated becomes a red papule. A yellow pustule forms when the acne becomes severely inflamed and fills with pus.

Epiduo is a treatment medication that works to address clogged pores and the proliferation of acne-causing bacteria, helping to reduce acne breakouts and prevent them from worsening.

The next section explains the specific actions of Epiduo’s active ingredients.

How the Active Ingredients in Epiduo — Adapalene and Benzoyl Peroxide — Work

The active ingredients in Epiduo are adapalene and benzoyl peroxide.

Adapalene regulates skin keratinization to help unclog pores. Because clogged pores are a key cause of acne, it works to prevent the formation of comedones (a condition in which sebum accumulates inside the pore).

Benzoyl peroxide, through its antibacterial action, suppresses the proliferation of C. acnes, while its peeling effect also helps to address clogged pores.

Through the combined action of these two ingredients, Epiduo works to treat acne.

What Effects Can Epiduo Provide? Improving Acne and Clogged Pores on the Nose

Epiduo may help improve acne and clogged pores, including on the nose.

It works to suppress skin keratinization while also exfoliating dead skin cells to help unclog pores. By targeting acne-causing bacteria such as C. acnes, it is a treatment medication aimed at helping to improve acne.

Some patients who did not find previous acne treatments effective have seen improvement in their acne after using Epiduo.

Can Epiduo Help with Post-Acne Hyperpigmentation? Other Treatments May Be More Suitable

Epiduo is not generally expected to have a direct effect on acne scars or post-inflammatory hyperpigmentation. It is primarily a topical medication aimed at treating active acne before scarring has a chance to develop.

Since it is intended to prevent acne scars from forming rather than to treat existing ones, a different approach is recommended for those wishing to address acne scars.

Treatment options for acne scars and hyperpigmentation include Dermapen 4 (Dermapen Microneedling) and subcision.

Dermapen 4 (Dermapen Microneedling) is a treatment that harnesses the skin’s natural healing ability to improve skin quality, while subcision is designed to address more severe scarring such as icepick or boxcar scars. For more details on acne scar treatments, please visit the page below.

Not Seeing Results from Epiduo? How Long It Takes to Notice Improvement

With Epiduo treatment, some patients begin to notice a reduction in acne around two weeks after starting use.

As individual results vary, it is important to continue use for approximately two weeks as a guide, even if you do not notice an immediate effect.

Most patients begin to notice a treatment effect within three months of starting. If no improvement is observed within three months, please stop use and consult your doctor.

Are Epiduo’s Side Effects Severe? Stinging and Discomfort May Occur

Epiduo can cause a stinging or burning sensation as a side effect.

This stinging is caused by the strong stimulation from the peeling action of benzoyl peroxide. In addition to discomfort, skin peeling and dryness may also occur.

If dryness is a concern, please moisturize with a product suitable for acne-prone skin. It is also important to start with a small amount when first using the medication, and to rinse it off with water if you experience stinging or irritation.

How Long Do Redness, Itching, and Skin Peeling Last? Around Two Weeks as a Guide

Side effects such as redness, itching, and skin peeling tend to gradually improve after approximately two weeks of use.

Flaking and peeling are more likely to occur in the early stages of use. However, in most cases, the frequency of irritation diminishes as use continues.

Rather than stopping Epiduo on your own, please consult your doctor to adjust the amount applied or the area of application.

Managing Severe Peeling or Pain from Side Effects | Rinse Off After 15 Minutes

A technique known as “short contact therapy” can be helpful when side effects such as peeling or pain are pronounced.

Short contact therapy involves rinsing the medication off 15 minutes after application. Reducing the length of time Epiduo is in contact with the skin can help lessen side effects.

Once intense irritation subsides, gradually increase the contact time — for example, to 30 minutes, then 60 minutes — and adjust accordingly.

If side effects remain a concern, spacing out applications and monitoring your skin’s response is also an option.

If Irritant Contact Dermatitis Develops, Consider Topical Steroids

If a rash or irritant contact dermatitis develops, using a topical steroid is one option to consider.

If the reaction is confined to the area of application, monitoring with a moisturizer may be sufficient. However, if symptoms persist, a topical steroid may be used.

It is important to visit a medical institution for an examination first. If allergic contact dermatitis is diagnosed, Epiduo must be discontinued.

For rashes caused by Epiduo, a topical steroid of strong class or higher is generally recommended.

If Epiduo Causes Too Much Pain, Stop Use and Consult Your Doctor

If Epiduo causes severe pain, intense redness, swelling, or a rash, it is important to stop use and consult your doctor.

In such cases, the cause is more likely to be irritation from the peeling action rather than an allergic reaction.

In rare cases, side effects from Epiduo may include weeping, swollen skin or contact dermatitis. If you experience pain or symptoms that are difficult to tolerate, please stop use immediately and seek medical advice.

How to Use Epiduo Gel Correctly | Apply in the Evening Before Bed

The correct way to use Epiduo Gel is to apply it once daily after cleansing, in the evening before going to bed.

Avoid applying it to the area around the eyes and mouth, mucous membranes, or any broken skin such as popped pimples. Wash your hands after application.

Since invisible “microcomedones” — tiny clogged pores — are present around active breakouts, it is also important to spread the gel beyond the visible pimple.

Once your skin has adjusted to the product, apply an amount roughly the size of one fingertip (up to the first knuckle of the index finger) and spread it over the entire face.

Tips for Using Epiduo Effectively: Apply Lotion or Emulsion Before Use

The most effective way to use Epiduo is to follow the correct application method.

Incorrect use may not only reduce the expected benefits but can also lead to more pronounced side effects.

Applying a toner (lotion) or emulsion to the skin before using Epiduo can help guard against dryness and reduce skin irritation.

Avoid Using Epiduo During Pregnancy or While Breastfeeding

Those who are pregnant, breastfeeding, or planning to become pregnant should avoid using Epiduo, as it may pose a risk to the fetus.

In addition, those who have previously experienced an allergic reaction to any ingredient in Epiduo should also avoid its use.

During Epiduo treatment, the skin is more sensitive to UV exposure due to the peeling effect, so thorough sun protection — including a parasol, hat, and sunscreen — is important.

Epiduo also has a bleaching effect, so care should be taken to keep it away from hair and clothing.

What to Expect After Starting Epiduo

The following table outlines what patients may expect after starting Epiduo.

Duration of Use Expected Progress
Day 1 – Week 2 ・Redness, skin peeling, and stinging discomfort may occur
・Symptoms often improve with continued use
・Dryness may persist for around one month
Week 2 – Month 3 ・Acne gradually begins to reduce
・Patients may start to notice improvement
Month 3 – Month 12 ・Acne continues to reduce, though breakouts may still occur due to other factors such as stress
・Continued use as directed by your doctor to help maintain the improvement

Acne can be recurring. To address clogged pores — one of the key causes of acne — it is important to continue using Epiduo as directed by your doctor.

Differences Between Epiduo, Bepio Gel, and Differin

In addition to Epiduo, other acne treatment medications include Bepio Gel and Differin. The key differences are outlined below.

Medication Epiduo Bepio Gel Differin
Ingredients ・Adapalene
・Benzoyl peroxide
・Benzoyl peroxide ・Adapalene
Effects ・Suppresses keratinization
・Antibacterial action against C. acnes
・Peeling action
・Antibacterial action against C. acnes
・Peeling action
・Suppresses keratinization
Features ・Used for patients who have not responded adequately to a single acne treatment medication ・Strong oxidizing action ・Has a mechanism similar to retinoids (vitamin A derivatives)

Because Epiduo combines Bepio Gel and Differin into a single medication, it may offer the benefits of both treatments in one product. However, as it may not suit every skin type, treatment may begin with Bepio Gel or Differin before transitioning to Epiduo.

For more detailed information about Bepio Gel, please also refer to the page below.

Where Can You Get Epiduo Gel? Is It Available Over the Counter at Pharmacies?

Epiduo Gel is not an over-the-counter product available at pharmacies.

As it is classified as a prescription medication, it must be prescribed by a dermatology clinic or medical clinic that handles Epiduo Gel.

Because Epiduo Gel has a strong effect, side effects are more likely to occur. Depending on the nature and severity of acne, Bepio Gel or Differin may be prescribed instead.

Can Epiduo Gel Be Purchased Online? Personal Importation Carries Risks

Epiduo Gel can be found for purchase online.

However, products imported from overseas by third-party sellers are not subject to verification under Japan’s Act on Securing Quality, Efficacy and Safety of Products Including Pharmaceuticals and Medical Devices, and caution is strongly advised.

There is also a risk that such products may be counterfeits made to resemble the genuine manufacturer’s product.

The risks of purchasing Epiduo Gel through personal importation outweigh any potential benefits. Please visit a medical institution to obtain a proper prescription.

Epiduo Gel: A Topical Medication That May Offer Meaningful Benefits for Acne

Epiduo Gel is a topical medication that combines Bepio Gel and Differin.

It works to address acne through three main mechanisms:

  • Suppression of keratinization
  • Peeling action
  • Antibacterial action

The active ingredient adapalene suppresses keratinization to help unclog pores. Benzoyl peroxide further removes dead skin cells and helps suppress both the proliferation of C. acnes and the formation of clogged pores.

While Epiduo Gel may offer meaningful improvements for acne, side effects can occur, so it is important to use it correctly and in consultation with your doctor. If you are troubled by acne, please consider speaking with us about Epiduo Gel.
