Actinic Keratosis: Causes, Risks, and What You Can Do
When your skin has been beaten down by too much sun over the years, it can develop rough, scaly patches called actinic keratosis, a precancerous skin condition caused by long-term UV exposure. Also known as solar keratosis, it’s not just a cosmetic issue—it’s a warning sign your skin has been damaged enough to risk turning into squamous cell carcinoma. This isn’t something that goes away on its own. If you’ve spent hours in the sun without protection—whether from work, sports, or just hanging out—you’re at risk, especially if you’re over 40, have light skin, or live in a sunny area.
Actinic keratosis doesn’t happen overnight. It builds up slowly, often starting as a tiny, dry spot that feels like sandpaper. You might ignore it, thinking it’s just dry skin. But if it sticks around, grows thicker, or starts to itch or bleed, it’s time to get it checked. It often shows up on places you can’t easily cover: your face, ears, scalp (if you’re bald), neck, hands, and arms. People who use tanning beds or have had organ transplants are also at higher risk. And while not every patch becomes cancer, studies show that up to 10% of untreated actinic keratoses can turn into skin cancer over time.
What helps? topical treatments, medicated creams and gels applied directly to the skin to destroy abnormal cells like fluorouracil, imiquimod, or ingenol mebutate can clear patches without surgery. cryotherapy, freezing lesions with liquid nitrogen is another common, fast option used by dermatologists. And prevention? It’s simple: wear sunscreen daily, even in winter. Cover up. Avoid the sun between 10 a.m. and 4 p.m. And check your skin every month. If you see a new rough patch that won’t go away, don’t wait. Early action stops it before it becomes something worse.
