Sitting in the sun for a prolonged period may be pleasant, but it can harm your skin in the long run. One of the skin issues that can occur is actinic keratosis. These are dry, scaly areas that develop on your skin after it has been exposed to excessive sun over the years.
The good news is that actinic keratosis can be treated if caught early. In this blog, you will explore all about actinic keratosis, including its causes, appearance, and treatment options.
Let’s get into all the details.
What Is Actinic Keratosis?
Actinic keratosis is a dry, rough, scaly skin patch. It results from prolonged sun exposure over several years. The patches themselves may not appear to be a concern at first, but they are precancerous. That is to say, they could develop into skin cancer if left untreated.
They are not necessarily easy to spot initially. They might gradually become like sandpaper or a very small scab. Other individuals don’t feel them until they become red, sore, or start to peel.
Most individuals have more than one patch, particularly on areas of the body that are frequently exposed to the sun.
You may also hear it referred to as solar keratosis. It’s not immediately dangerous, but it is a signal that your skin has been injured.
What Causes Solar Keratosis?

Actinic keratosis results from the sun’s or a tanning bed’s ultraviolet (UV) radiation. These are the primary causes:

Spending lots of time outdoors without using sunscreen or wearing protective clothing allows UV rays to damage your skin. This damage accumulates over time, increasing your risk.
Sunburns, Especially at a Young Age
Getting sunburnt, particularly during childhood or teenage years, can deeply harm the skin cells. Even if your skin healed then, the effects may show up later as rough, scaly patches.
Tanning beds give off intense UV radiation, just like the sun. Regular use increases your chance of developing skin problems, including actinic keratosis and even skin cancer.
Having Fair Skin that Burns Easily
Individuals with pale or fair skin are more susceptible to the sun’s effects. If your skin turns red quickly in sunlight, it means it’s more likely to be damaged by UV rays.
If someone’s immune system is weak (due to illness, medication, or age), their body might not be able to repair sun damage properly. This makes it easier for sun damaged skin cells to turn into actinic keratosis.
Actinic keratosis doesn’t happen overnight. It builds up slowly over decades. Even brief periods in the sun, without proper care, can accumulate over time and lead to rough patches appearing later in life.

Now, let’s see who can get it.
Who is at Risk of Getting Sun Keratosis?
Anyone can develop actinic keratosis, but some individuals have a greater risk than others. You are more likely to develop it if you:

- Are older than 50 years.
- Have fair skin, light-coloured eyes (blue or green), and light-coloured hair (blonde or red).
- Have spent considerable time in the sun for employment or recreation.
- Have experienced many sunburns.
- Use sunbeds or tanning lamps.
- Take medications that suppress your immune system.
What Does Actinic Keratosis Look Like? (Symptoms)
Here’s what to be aware of:
- Dry, scaly, or crusty patches that won’t heal.
- The patches can be red, pink, skin-coloured, or brown.
- They are rough, similar to sandpaper.
- Some are itchy, sting, or are sore.
- The area may bleed or develop into a hard lump later.
Actinic keratosis typically appears on the areas of the body that are exposed to the sun more often. These include your:
- Face
- Scalp (particularly in bald men)
- Ears
- Neck
- Forearms
- Back of hands
- Shoulders
- Chest
- Lower legs
Most patches are tiny, but some become larger or spread. If left untreated, some develop squamous cell carcinoma (skin cancer).
Professional Treatments for Actinic Keratosis Skin
Here are advanced options to treat the skin affected with solar keratosis:

Neogen Plasma Treatment is a relatively new procedure that utilises a unique form of energy to treat injured skin. It involves releasing a soft wave of plasma (which is created from nitrogen gas) over the surface of the skin. Plasma heat destroys damaged cells, allowing healthy new skin to develop.
What’s unique about Neogen Plasma is that it treats the whole surface of the skin, not a single patch. This makes it highly beneficial for individuals with numerous patches or sun-damaged areas that are broad, such as those on the face or scalp.
UltraClear Laser Resurfacing
UltraClear laser resurfacing is a potent procedure that exfoliates the top layers of sun-damaged skin with a focused beam of light. It works particularly well for treating multiple patches at once, especially on the face or scalp. The laser eliminates the sun-damaged skin cells and stimulates the skin to produce new, healthy layers underneath.
Practitioners tend to use this technique when the skin is severely sun-damaged or when numerous actinic keratosis lesions are clustered together.
If you wonder how to get rid of freckles, know that UltraClear Laser Resurfacing can be your answer.
Chemical peels work by peeling the outer layers of the skin with a special acid solution. This removes damaged skin cells, making way for new, healthier skin to develop. The treatment is frequently applied to the face and is well-suited for use on numerous small patches or uneven, sun-damaged areas.
It works particularly well for individuals who would like to treat early actinic keratosis while enhancing the appearance of their skin.
Cryotherapy is one of the most popular treatments for actinic keratosis. It is usually used for one or two patches. During this treatment, the practitioner sprays the patch with liquid nitrogen. The intense cold freezes and kills the abnormal skin cells.
After treatment, the patch can blister and then develop a scab. Within the next several weeks, the scab will crack off, and new, healthy skin will replace it. Cryotherapy is a fast treatment that is always performed in a clinic.
Curettage is a minor surgery performed on thicker or more persistent patches. In a curettage, the practitioner utilises a sharp device called a curette to remove the affected skin. At times, the doctor uses heat (referred to as electrocautery) to kill the remaining cells and prevent bleeding.
This is typically carried out under local anaesthetic, so the area is made insensitive, and you will feel no pain at all while undergoing the procedure.
Doctors may also use special creams to treat actinic keratosis. These creams help destroy damaged cells or support your body’s immune system in removing them. They are often used when there are many small patches or when the patches cover a wide area, such as the face or scalp. If you want to try, consult a specialist who prescribes the topical cream solutions.
Everyday Care & Prevention Tips for Solar Keratosis
Even if your doctor is treating the patches, daily home care is equally important. These easy steps can prevent new patches from developing and shield your skin from additional sun damage.
Apply Sunscreen Every Day, Must!
Select one with an SPF of at least 30 and ensure it is labelled as “broad-spectrum” to protect against both UVA and UVB rays. Use it on all exposed skin, even on winter days or cloudy days, and reapply every 2 hours if you plan to be outside.
Protect Your Skin With Clothing
Wear long sleeves, long pants, and a wide-brimmed hat to protect your skin from the sun’s rays, as they can harm your skin. There are also UV-blocking clothes, which are particularly useful for individuals who spend a lot of time outside or have extremely fair skin.

Wear UV-Protecting Sunglasses.
Your eyes and the skin around your eyes can also be damaged by the sun. Select sunglasses that specifically state they block 100% of UV rays to protect this delicate area.
Avoid Sun Exposure At Specific Times
Attempt to avoid the direct sun between 11 a.m. and 3 p.m., when the UV rays are most intense. Sit in the shade of trees, use an umbrella, or take early morning or late afternoon walks.
Avoid Sun Beds & Tanning Booths
They emit intense UV rays that are more damaging to the skin than the sun. Exposure to them increases your chances of getting new patches and developing skin cancer.
Check Your Skin Regularly
Examine your skin every few weeks for new dry areas, ulcers, or spots that do not heal. If something appears or feels different, particularly if it bleeds, enlarges, or crusts over, consult a healthcare professional.
What is the Difference Between Keratosis and Actinic Keratosis?
Keratosis refers to the thickened or rough areas on the skin that result from the accumulation of keratin. It encompasses benign forms such as seborrhoeic keratosis and keratosis pilaris.
On the other hand, actinic keratosis is a special form caused by sun damage and may develop into skin cancer if left untreated. Therefore, all actinic keratosis is keratosis, but not all keratosis is actinic.
Can Actinic Keratosis Turn Into Skin Cancer?
Can a rough patch of actinic keratosis become cancer? In some cases, yes. Actinic keratosis isn’t cancer, but it may become squamous cell carcinoma (SCC), a form of skin cancer. This doesn’t occur in all cases, but experts usually comment:
- Around 1 in 10 untreated AKs could become SCC.
- The risk is greater if the patch is thick, tender, or enlarging.
- That is why treatment and early examination are so crucial.
When to See a Doctor?
Consult your doctor or a skin specialist if:
- You notice new rough patches that don’t go away.
- The damaged skin patch gets bigger, bleeds, or hurts.
- The skin looks red, raised, or starts to change shape.
- You have lots of spots and don’t know what they are.
Regular skin checks are also advisable if you have been getting more than usual sunburns or excessive sun exposure.
Final Thoughts
Actinic keratosis may seem like just dry skin, but it is a warning sign from your body. It indicates that your skin has been damaged by the sun for many years. While the patches are not cancerous at first, they can become skin cancer if ignored. That’s why it’s so important to notice the signs early and get help from a doctor.
Moreover, if you are looking to address skin damage caused by actinic keratosis, consult with experts for advanced treatments such as Ultraclear Laser Resurfacing, NeoGen Plasma, Chemical Peels, or topical creams.
Protecting your skin from harmful sun rays, applying sunscreen with SPF, and avoiding tanning booths may help prevent this condition.
FAQs
1. What is the best cure for actinic keratosis?
There is no single cure, but many treatments work well. These include freezing (cryotherapy), creams, laser resurfacing, chemical peels, and plasma therapy. The proper treatment depends on the number of patches you have and the extent of skin damage.
2. What stage is actinic keratosis?
Actinic keratosis is considered a precancerous condition. This means the patches are not cancer yet, but could turn into squamous cell carcinoma (a type of skin cancer) if not treated. It’s an early warning sign that should not be ignored.
3. What is the new treatment for actinic keratosis?
Neogen Plasma is a newer treatment. It uses a soft wave of heat to treat sun-damaged skin. It works well on larger areas and helps the skin heal while enhancing its appearance. It’s often used in conjunction with other methods, such as lasers or creams.
4. Does actinic keratoses spread?
They don’t “spread” like an infection, but new patches can form over time, especially if your skin keeps getting sun damage.
