In some animal studies, tretinoin has been shown to cause skin tumors to develop faster when the treated area is exposed to ultraviolet light (sunlight or artificial sunlight from a sunlamp). Other studies have not shown the same result and more studies need to be done. It is not known if tretinoin causes skin tumors to develop faster in humans.
Along with its needed effects, tretinoin topical (the active ingredient contained in Retin A Micro) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor as soon as possible if any of the following side effects occur while taking tretinoin topical:More common
- Burning feeling or stinging skin (severe)
- lightening of skin of treated area, unexpected
- peeling of skin (severe)
- redness of skin (severe)
- unusual dryness of skin (severe)
- Darkening of treated skin
Some side effects of tretinoin topical may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:More common
- Burning feeling, stinging, or tingling of skin (mild)—lasting for a short time after first applying the medicine
- chapping or slight peeling of skin (mild)
- redness of skin (mild)

The side effects will go away after you stop using tretinoin. On the rare chance that your skin color changes, this effect may last for several months before your skin color returns to normal.
