Actinic Keratosis: Rough, Sandpaper-Like Spots From Chronic Sun Exposure

Actinic keratosis, often called AK, is a rough or sandpaper-like spot that can develop after years of sun exposure. These spots are common on areas that receive steady ultraviolet light, such as the face, scalp, ears, chest, forearms, hands, and lips.

Because actinic keratoses are considered precancerous, they deserve thoughtful attention rather than guesswork. Not every rough spot is an AK, and not every AK behaves the same way, which is why a dermatologist evaluation is the safest next step when a patch is new, persistent, changing, tender, bleeding, or simply unfamiliar.

Quick answer

• Actinic keratosis is a rough, scaly, or sandpaper-like skin growth linked to long-term ultraviolet exposure.
• It is most often found on sun-exposed skin, including the face, scalp, ears, hands, forearms, chest, and lips.
• AKs are considered precancerous because some may develop into squamous cell carcinoma over time.
• A dermatologist can evaluate the spot, confirm what it is, and discuss appropriate treatment options.
• Daily sun protection and regular skin checks are important parts of ongoing care.

What actinic keratosis is

Actinic keratosis is a sun-related change in the upper layers of the skin. It may feel rough before it is easy to see, which is why some people first notice it by touch while washing their face, shaving, applying moisturizer, or running a hand over the scalp or arms.

AKs can look pink, red, tan, brown, skin-colored, or crusted. Some are flat, while others feel slightly raised. They may come and go, but a recurring rough patch on sun-exposed skin should not be ignored. A dermatologist can help determine whether the spot is an actinic keratosis, another benign growth, irritation, or something that needs additional testing.

Common causes and risk factors

The main driver is cumulative ultraviolet exposure. For many people in South Florida, that can include years of beach time, boating, golf, tennis, walking, gardening, outdoor work, travel, and incidental daily sun. Snowbirds and international visitors may also have a lifetime of sun patterns from different climates, which can matter during a skin evaluation.

• Long-term sun exposure over many years
• Indoor tanning exposure
• Fair skin, light eyes, or a tendency to burn easily
• A history of frequent sunburns
• Older age, because sun damage accumulates over time
• Outdoor hobbies, sports, or work
• A weakened immune system or history of skin cancer

What you can do at home

At-home care cannot confirm a diagnosis, but it can support healthier habits while you wait for an appointment. Protect the area from additional ultraviolet exposure, avoid picking or scraping rough spots, and keep note of any changes in size, color, texture, tenderness, crusting, or bleeding.

• Use broad-spectrum sunscreen as directed on exposed skin.
• Wear a wide-brimmed hat, UV-protective clothing, and sunglasses when outdoors.
• Seek shade, especially during peak sun hours.
• Avoid indoor tanning.
• Take clear photos of a concerning spot if you are monitoring a change before your visit.
• Do not try to burn, freeze, cut, or remove a suspected AK at home.

Professional options

Treatment depends on the number of spots, where they are located, how they look and feel, your medical history, and whether the dermatologist sees any features that need closer evaluation. Common professional options may include cryotherapy, prescription field therapies, photodynamic therapy, curettage, laser-based approaches, or a biopsy when the diagnosis is uncertain or a spot has concerning features.

These options are not interchangeable for every person. Your clinician can help you understand which approach may be appropriate after examining your skin. At Waverly DermSpa, we offer Photodynamic Therapy (PDT) and can help you understand whether it may be appropriate.

When to see a dermatologist

It is worth scheduling a dermatologist visit for a rough spot that persists, returns, grows, becomes painful, bleeds, crusts repeatedly, or looks different from your other skin marks. A skin check is also important if you have many sun-damaged areas, a personal history of skin cancer, or a spot on the lip, ear, scalp, face, or back of the hands.

Prompt evaluation does not mean panic. It means giving your skin the benefit of trained eyes, especially when a spot has been shaped by years of ultraviolet exposure.

FAQ

Is actinic keratosis skin cancer?

Actinic keratosis is generally described as a precancerous skin growth, not the same as a diagnosed skin cancer. Because some AKs may develop into squamous cell carcinoma, evaluation and follow-up are important.

What does actinic keratosis feel like?

Many people describe AKs as rough, dry, scaly, gritty, or sandpaper-like. Some are easier to feel than see, especially early on.

Can moisturizer make it go away?

Moisturizer may soften dry skin, but it does not diagnose or treat a suspected actinic keratosis. If a rough spot persists despite basic skincare, a dermatologist should evaluate it.

Should I be worried if I have more than one?

Multiple rough spots can be a sign of cumulative sun damage. A dermatologist can examine the full area and discuss whether spot treatment, field treatment, or ongoing surveillance makes sense.

Can actinic keratosis come back after treatment?

Some people develop new AKs over time because prior sun damage remains part of the skin’s history. Consistent sun protection and regular skin checks can help support long-term monitoring.
