Actinic keratosis develops as a result of cumulative sun damage over time, particularly in individuals with fair skin, light-colored eyes, or a history of frequent sun exposure. UV radiation damages skin cells, leading to abnormal growths that can eventually become cancerous. Occasionally, AKs may itch or produce a pricking or tender sensation in the skin. Some lesions naturally disappear only to reappear later, and it is common to see several actinic keratoses at a time. Early detection and treatment are key to preventing progression and reducing the risk of developing skin cancer.
Symptoms of actinic keratosis include:
- Rough, scaly patches that may be red, brown, or skin-toned
- Lesions on sun-exposed areas such as the face, scalp, and arms
Sensitivity or discomfort in the affected areas
