Below you’ll find answers to a few commonly asked questions about tretinoin topical cream.

How does tretinoin compare with other similar drugs, such as retinol?

Tretinoin and retinol are not the same thing, but they are both retinoids. Retinoids are a group of compounds that are similar to vitamin A.

Retinol is a type of retinoid that’s found in many over-the-counter (OTC) skin care products. Retinol isn’t approved for treating acne or any other skin condition. 

Examples of retinoids that are approved to treat acne include:

• prescription tretinoin cream (Avita, Retin-A)
• adapalene gel (Differin), which is an OTC retinoid

OTC retinoids aren’t as strong as prescription versions. So, you may not see the same results as you would using a prescription retinoid. But OTC retinoids are usually gentler on your skin.

To learn more about different retinoid products, talk with your doctor or pharmacist. You can also read this article to learn more about how tretinoin and retinol compare.

Can tretinoin be used for wrinkles, stretch marks, rosacea, or dark spots?

Possibly. Tretinoin cream isn’t approved to treat wrinkles, stretch marks, rosacea (a type of skin condition), or dark spots. But doctors may choose to prescribe it off-label for anti-aging effects or other uses. An off-label use is when doctors prescribe a drug for a purpose other than its approved use.

Talk with your doctor if you have questions about using tretinoin cream for conditions other than acne.

Is it safe to use tretinoin with niacinamide, clindamycin, or benzyl peroxide?

Yes, it’s generally safe to use tretinoin cream with other topical acne treatments, such as niacinamide, clindamycin, and benzyl peroxide. But it’s important to be cautious when you use these drugs together.

Tretinoin cream can dry or irritate your skin. If other topical products also cause dryness or irritation, they could interact if you take them with tretinoin. Topical niacinamide, clindamycin, and benzoyl peroxide can all cause these side effects to some extent. If you’re using these products with tretinoin cream, stop them if your skin becomes too dry, red, discolored, or irritated.

Talk with your doctor before combining tretinoin cream with other topical treatments.

How does tretinoin work? And how long does it take to start working?

Tretinoin cream works by increasing skin cell turnover. This means skin cells grow and divide faster. As a result, dead skin cells are removed from the skin surface and pores more quickly. This helps treat acne.

You should notice results from using tretinoin cream after 2 to 3 weeks. But it can take up to 12 weeks to see the full effects of the drug.

Talk with your doctor to learn more about what to expect when using tretinoin cream.

Does tretinoin expire?

Yes, tretinoin will expire. The drugmaker will put an expiration date on the tube of tretinoin cream. After that date, the drug may be less effective. Using expired tretinoin isn’t likely to cause harm. But it may not work as well as it should.

If you have expired tretinoin, call your doctor or pharmacist to get a new prescription or learn how to dispose of it. You can also view this article to learn more about how to safely dispose of medications.

Is there a best time of day to use tretinoin? What should I do if I miss a dose?

Yes, the recommended time of day to use tretinoin cream is before bedtime after you wash your face. You’ll wait 20 to 30 minutes for your skin to completely dry. Then, you’ll apply enough cream to lightly cover the areas with acne.

If you miss a dose of tretinoin cream, apply it as soon as you remember. If it’s already the next day, skip the missed dose and apply the next dose at the regular time. This is usually before bedtime. Do not double the dose in one day. Applying doses too close together, such as twice in one day, may irritate your skin.

For questions about how to use tretinoin, talk with your doctor or pharmacist.
