Actinic keratosis is a common sun-related skin condition. Learn when treatment is indicated and why monitoring is important.
Actinic keratosis is a common skin condition caused by long-term sun exposure. It often appears as rough, scaly patches on sun-exposed areas of skin, such as the face, scalp, ears, hands, and forearms.
While actinic keratosis is not skin cancer, it is considered precancerous, meaning it has the potential to develop into a type of skin cancer if left untreated. Because of this, understanding what actinic keratosis is — and when it should be treated — is an important part of protecting long-term skin health.
This office is wonderful! Dermatologists are notoriously difficult to get in to timely, St. Louis Dermatology in Troy is so easy to get an appointment at (the “longest” I’ve waited is a week for a non-urgent appointment). Kayleigh is an excellent provider, remembers your previous visits and concerns, and doesn’t rush through the appointments. The in office procedures they offer as well are very convenient and often saves you on your out of pocket costs with insurance when the in office procedures are billed with your office visit. So grateful to have such a great local derm!

I absolutely love this office. They handled my surgery with exceptional care, and I can finally say I’ve found the right team. I drive 55 minutes for every appointment because Dr. Beal and his staff are truly outstanding. Their professionalism, compassion, and commitment to patient care make the trip more than worth it. I always feel supported and confident that I’m receiving the best possible care. Highly recommend!
