Safety and Effectiveness Study of Imiquimod Creams for the Treatment of Actinic Keratoses (AKs)

The purpose of this study is to determine whether imiquimod creams are effective in treating Actinic Keratoses when applied to the face or balding scalp. Actinic keratosis (AK) is a skin condition that shows up on skin routinely exposed to the sun, such as the face, scalp, shoulders, chest, back, arms, and hands. The active ingredient contained in the study cream for this study is the same as that of the approved product Aldara, which has shown to be safe and effective for the treatment of AKs.
