Wash your hands before applying this medication. Gently clean the affected skin with a mild or soapless cleanser and pat dry. Use your fingertips to apply a small amount of medication (about the size of a pea) in a thin layer as directed by your doctor, usually once daily at bedtime. A gauze pad or cotton swab can be used to apply the liquid. For some preparations, you should wait 20 to 30 minutes after cleaning your face before applying this medication. Consult the label directions, the Patient Information Leaflet, or your pharmacist if you have any questions.

Use this medication on the skin only. Do not apply to the inner lip area or inside the nose/mouth. Do not apply to cut, scraped, sunburned, or eczema-affected skin.

Avoid getting this medication in your eyes. If this medication gets into your eyes, flush with large amounts of water. Call your doctor if eye irritation develops. Wash your hands after using the medication to avoid accidentally getting it in your eyes.

During the first few weeks of using tretinoin, your acne might appear worse because the medication is working on pimples forming inside the skin. It may take up to 8-12 weeks to notice results from this medication.

Use it regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. Do not use a larger amount or use it more often than recommended. Your skin will not improve any faster, and it will increase the risk of developing redness, peeling and pain.

This medication is available in different strengths and forms (such as gel, cream, solution). The best type of medication for you to use will depend on the condition of your skin and your response to treatment. Tell your doctor if your condition lasts or gets worse.

Warmth or stinging may occur right after applying the medication. Skin redness, dryness, itching, scaling, mild burning, or worsening of acne may occur during the first 2 to 4 weeks of using the medication. These effects usually decrease with continued use. A daytime moisturizer may be helpful for very dry skin (see Notes). If any of these effects last or get worse, tell your doctor or pharmacist promptly.
