Actinic keratoses (AKs), also known as solar keratoses, are small rough or scaly areas of skin due to damage from sun exposure. Some AKs can turn into squamous cell skin cancer, so it is important to perform self-examinations often and catch them early. Spots usually appear in those who are older (over 50), but they can start appearing in younger adults who have had a lot of sun exposure. Darker-skinned individuals are rarely affected.
