Answer

Topical Skin Products

The agent imiquimod has been reported to show some efficacy. However, the mechanism of action of imiquimod cream in treating keratosis is unknown.

Imiquimod (Aldara, Zyclara)

Imiquimod is an immune response modifier currently approved for the treatment of genital and perianal warts. It is capable of inducing IFN-alpha, TNF-alpha, IL-1, IL-6, and IL-8. Studies using 5% cream in mice showed significant induction of IFN-alpha at the application site occurring as early as 2 hours after treatment. At 4 hours after application, increases in IFN-alpha mRNA levels were found, indicating an increase in transcription. It is not approved by the FDA for use in hypertrophic scars and keloids.
