Retin-A Micro (Topical)

Tretinoin is used to treat acne or other skin conditions as decided by your doctor. It helps to keep skin pores clear.

One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by sun damage. It works by lightening the skin, replacing older skin with newer skin, and slowing down how the body removes skin cells that may have been damaged by the sun. Tretinoin works best when used as part of a skin care routine that includes protecting the treated skin from the sun. However, it does not completely or permanently remove these skin issues or significantly improve more noticeable skin changes, such as deep wrinkles caused by the sun or natural aging.

This medicine is available only with your doctor's prescription.

It is very important that your doctor checks your or your child's progress at regular visits to ensure that this medicine is working correctly and to look for any unwanted effects.

During the first 3 weeks of using tretinoin, your skin may become irritated. Additionally, your acne might seem to worsen before it improves. It may take more than 12 weeks to see full improvement of your acne, even if you use the medicine every day. Contact your doctor if skin irritation becomes severe or if your acne does not improve within 8 to 12 weeks.

You should avoid washing the skin treated with tretinoin for at least 1 hour after applying it.

Do not use any topical medicine on the same area within 1 hour before or after using tretinoin. Otherwise, tretinoin may not work properly or skin irritation might occur.

Unless your doctor advises otherwise, it is especially important to avoid using the following skin products on the same area as tretinoin:

• Any other topical acne product or skin product containing a peeling agent (e.g., benzoyl peroxide, resorcinol, salicylic acid, or sulfur).
• Hair products that irritate the skin, such as permanents or hair removal products.
• Skin products that cause sensitivity to the sun, including those with spices or limes.
• Skin products that contain a large amount of alcohol (e.g., astringents, shaving creams, or after-shave lotions).
• Skin products that are too drying or abrasive, such as certain cosmetics, soaps, or skin cleansers.

Using these products along with tretinoin may cause mild to severe skin irritation. Although skin irritation can happen, some doctors may allow the use of benzoyl peroxide with tretinoin to treat acne. Usually, tretinoin is applied at night so that it does not interfere with any other topical products you might use during the day. Check with your doctor before using other topical medicines with tretinoin.

During the first 6 months of use, avoid overexposing the treated areas to sunlight, wind, or cold weather. Your skin will be more sensitive to sunburn, dryness, or irritation, especially during the first 2 or 3 weeks. However, you should not stop using this medicine unless the skin irritation becomes too severe. Do not use a sunlamp.

To help tretinoin work effectively, regularly use sunscreen or sunblocking lotions with a sun protection factor (SPF) of at least 15. Also, wear protective clothing and hats, and apply creams, lotions, or moisturizers frequently.

Contact your doctor if your skin becomes too dry and irritated. Your doctor can help you choose the right skin products to reduce dryness and irritation, which may include the following:

• For patients using tretinoin for acne: Regular use of water-based creams or lotions helps reduce skin irritation or dryness caused by tretinoin.
• For patients using tretinoin for fine wrinkling, dark spots, and rough skin from sun exposure: This medicine should be part of an ongoing program to prevent further skin damage from the sun. This program includes staying out of the sun when possible or wearing appropriate clothing or hats for skin protection. Regular use of oil-based creams or lotions helps reduce skin irritation or dryness caused by tretinoin.
