Topical Retinoids

Retinoids are drugs connected to vitamin A and affect certain genes involved in the growth and maturation of cancer cells. Some retinoids can be applied directly to skin lesions as a gel. Treatment with topical retinoids can result in irritation, itching, and redness in the area where the drugs are applied. They can also cause increased sensitivity to sunlight in the treated area. Women who are pregnant or could become pregnant should not be given topical retinoids, as the drugs can cause serious birth defects.
