Actinic keratosis, also known as solar keratosis, is a common skin condition caused by prolonged exposure to the sun's ultraviolet (UV) rays. It is characterized by the appearance of rough, scaly, or crusty patches on the skin, typically on sun-exposed areas such as the face, ears, lips, and hands. As a dermatology expert with over a decade of experience in diagnosing and treating skin conditions, I will provide a comprehensive guide on how to spot actinic keratosis images and symptoms, and discuss the importance of early detection and treatment.
Understanding Actinic Keratosis: Causes and Risk Factors
Actinic keratosis is a type of skin lesion that occurs due to chronic sun exposure, which damages the skin’s DNA and leads to abnormal cell growth. The risk factors for developing actinic keratosis include:
- Prolonged sun exposure, especially during childhood and adolescence
- Fair skin, light hair, and blue or green eyes
- History of sunburns or skin cancer
- Weakened immune system
- Age, with most cases occurring in people over 40 years old
