Tretinoin (TRET-i-noyn) is used to treat acne. It works partly by keeping skin pores clear. One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by damaging rays of the sun. It works by lightening the skin, replacing older skin with newer skin, and by slowing down the way the body removes skin cells that may have been harmed by the sun.

Precautions While Using This Medicine

During the first 3 weeks you are using tretinoin, your skin may become irritated. Also, your acne may seem to get worse before it gets better. It may take longer than 12 weeks before you notice full improvement of your acne, even if you use the medicine every day. Check with your health care professional at any time 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.

Avoid using 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 tells you 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 (such as benzoyl peroxide, resorcinol, salicylic acid, or sulfur)

- Hair products that are irritating, such as permanents or hair removal products

- Skin products that cause sensitivity to the sun, such as those containing spices or limes

- Skin products containing a large amount of alcohol, such as astringents, shaving creams, or after-shave lotions

- Skin products that are too drying or abrasive, such as some cosmetics, soaps, or skin cleansers

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

During the first 6 months of use, avoid overexposing the treated areas to sunlight, wind, or cold weather . The skin will be more prone 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 properly, 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 often.
