An actinic keratosis (AK) is a small, rough spot occurring on skin as a result of chronic sun exposure. They are usually red in color, but maybe dark brown, associated with sensitivity when touched. Also known as solar keratosis, actinic keratosis may lead to skin cancer.
The key to management of actinic keratosis is prevention. Daily use of sunscreen and sun protective device minimize the development of actinic keratosis. Treatment options include topical medications such as imiquimod, ingenol mebutate and 5 fluorouracil. Procedures are also available – cryotherapy, photodynamic therapy, powerphotofacial, and superficial medical grade peels.
