Actinic keratosis is a patch of rough, scaly skin that results from prolonged exposure to the sun. These patches typically appear on the face, lips, ears, forearms, scalp, neck, or back of the hands.
Scaly spots or patches on the top layer of the skin are called actinic keratoses. These spots may become complicated with a wart-like surface over time. Actinic keratosis, also known as solar keratosis, typically develops slowly and is commonly found in people over 40. Minimising sun exposure and protecting your skin from ultraviolet (UV) rays is essential to reduce the risk of this skin condition. If left untreated, actinic keratoses may turn into squamous cell carcinoma, a type of skin cancer, with a risk ranging from 5% to 10%.
