Tretinoin and benzoyl peroxide are two of the most widely used acne treatments prescribed by dermatologists. When used correctly, they can complement each other and help treat both inflammatory acne and clogged pores.

However, many patients are confused about whether these ingredients can be combined, whether they should be used at the same time, and which prescription products are available.

This guide explains how tretinoin and benzoyl peroxide work together, what products exist, and what to know before starting treatment.

Can tretinoin and benzoyl peroxide be used together?

Yes! Tretinoin and benzoyl peroxide can be used together, and many dermatologists recommend this combination for acne treatment. Historically, combining the two ingredients in the same product was difficult because benzoyl peroxide can degrade tretinoin and reduce its stability. Newer formulation technologies have made combination products possible.

One FDA-approved prescription product that combines both ingredients is Twyneo, which contains tretinoin 0.1% and benzoyl peroxide 3%. Twyneo uses microencapsulation technology to help keep the ingredients stable in the same formulation.

Is Twyneo available through Miiskin?

Miiskin does not offer compounded tretinoin and benzoyl peroxide medications. Patients interested in using both ingredients together may ask for Twyneo prescription from their dermatologist, but this medication may expensive compared to using separate acne treatments.

What about adapalene and benzoyl peroxide?

Another commonly prescribed acne combination is adapalene with benzoyl peroxide.

Unlike tretinoin, adapalene is a newer retinoid that is more chemically stable when combined with benzoyl peroxide. Combination products containing adapalene and benzoyl peroxide have been available for years.

These treatments are often prescribed for mild to moderate acne and may be suitable for patients who experience irritation with tretinoin.

How to get a prescription for acne?

You can get a prescription for acne by having an online consultation with a dermatologist. Price of the consultation starts at $59 and it takes 1-2 days to get an answer. 

Should I apply benzoyl peroxide or tretinoin first?

If you are using two separate medications, you should apply benzoyl peroxide in the day time and tretinoin at night.

How to use benzoyl peroxide and tretinoin together?

Benzoyl peroxide and tretinoin can be used together in a skincare routine to address different aspects of acne. However, it is essential to use them carefully to minimize potential irritation. Here are some guidelines for using benzoyl peroxide and tretinoin together:

Start slowly

When incorporating these two products into your routine, it is best to start slowly to allow your skin to adjust. Begin with one of the products and use it every other night or every third night to see how your skin reacts.

If you are using two separate medications

If you are using two separate medications, you should apply benzoyl peroxide over the affected areas in the morning followed by sunscreen with a high SPF factor. You can use a cleanser, cream, or gel.

Tretinoin is always applied at night since it is sensitive to light. Apply it on clean, dry skin and use a pea-sized amount to spread it evenly over your face. It is also important to know that you should never apply these creams on damaged or injured skin.

If you are using a combination cream

If you are using a combination cream, you should apply it at night after washing your face and applying a gentle, non-comedogenic moisturizer.

Use sunscreen

Both benzoyl peroxide and tretinoin can make your skin more sensitive to the sun, so it is essential to use a broad-spectrum sunscreen with SPF 30 or higher during the day, even during winter or if you spend most of your time indoors.

Use a moisturizer

Both benzoyl peroxide and tretinoin can be drying and irritating to the skin. To protect your skin against excessive dryness, use a gentle, non-comedogenic moisturizer to keep your skin hydrated. Apply it in the morning and evening.

Monitor your skin for irritation

Pay close attention to how your skin reacts. If you experience excessive redness, peeling, or irritation, reduce the frequency of one or both products or consult your dermatologist for guidance. They may suggest adjusting the strengths or formulations of the products.

Remember that using both benzoyl peroxide and tretinoin together can be effective, but you need to use them carefully and under the guidance of a healthcare provider to minimize side effects and achieve the best results for your skin.

What results can I expect from using a benzoyl peroxide and tretinoin?

Less acne breakouts

Since they have very different mechanisms of action, together, benzoyl peroxide and tretinoin will help you reduce acne breakouts, and unclog pores, kill acne-causing bacteria, and promote the shedding of dead skin cells, which can lead to fewer breakouts over time^{4 5} .

Reduced inflammation

Both benzoyl peroxide and tretinoin have anti-inflammatory properties^{6 7} . They can help decrease the redness and swelling associated with active acne lesions, making your skin look less inflamed.

Reduction of oil production 

Benzoyl peroxide and tretinoin can also help reduce excess oil production, which can contribute to acne. By controlling oiliness, you can experience fewer breakouts^8 9 .

Improved skin texture

Tretinoin is known for its ability to improve skin texture. It promotes cell turnover, which can help fade acne scars, reduce the appearance of fine lines and wrinkles, and make your skin look smoother and more youthful¹⁰.

Potential side effects of using benzoyl peroxide and tretinoin together

• Dryness and peeling
• Skin irritation 
• Burning or stinging 
• Itchiness
• Sensitivity to sunlight
• Initial acne flare up (the so-called tretinoin purge)
• Increased sensitivity to other ingredients
• Allergic reactions¹¹

Can I use benzoyl peroxide and tretinoin long term?

The long-term use of benzoyl peroxide and tretinoin for the treatment of acne can be safe and effective for many individuals, but it should be done under the guidance of a healthcare provider or dermatologist.
