Also known an actinic keratosis, a solar keratosis is a scaly skin growth caused by prolonged exposure to sunlight. The growths typically appear on the face, ears, hands, and bald parts of the scalp. They have a rough texture and may be sore or itchy. Sometimes, a solar keratosis may develop into squamous cell carcinoma, a type of skin cancer.
Some keratoses may simply need to be monitored, and any changes should be checked by a doctor.
However, if they are troublesome or may become cancerous, they may be removed by freezing or scraping them off; by using a special cream or gel; or by using a type of light treatment called photodynamic therapy.
