Topical 5-fluorouracil (5-FU, Efudex, Carac) has been shown to be an effective therapy for diffuse, but minor actinic cheilitis. 5-fluorouracil works by blocking DNA synthesis. Cells that are rapidly growing need more DNA, so they accumulate more 5-fluorouracil, resulting in their death. Normal skin is much less affected.
