Managing Sun-Induced Skin Changes: A Guide to Actinic Keratosis

Actinic keratosis, also recognized as solar keratosis, is a common skin condition resulting from prolonged sun exposure. These skin patches are typically dry and scaly, with a texture likened to sandpaper. They can range in size from about 1 to 2 centimeters and exhibit hues from skin-toned to varying shades of pink, red, and brown. Occasionally, these patches may cause discomfort such as itching.

These patches are most frequently observed on sun-exposed areas, including the face, hands, arms, ears, scalp, and legs. It is advisable to consult a general practitioner (GP) if you detect new patches,dermoscopy of actinic keratosis or if existing ones start to bleed, increase in size, change color, become tender, or form a lump, especially on the lips. Early medical attention is crucial to rule out more severe conditions like skin cancer.

Treatment Options for Actinic Keratosis

In cases where a single patch of actinic keratosis is present, a GP may advise monitoring to see if it resolves on its own. However, when multiple patches are present or if a patch is problematic, causing pain or itchiness, medical intervention is typically advised. A GP may refer you to a dermatologist, who can offer various treatments, such as:

Prescription topical creams and gels.

Cryotherapy, which involves freezing the patches, causing them to blister and eventually peel off.

Surgical removal or curettage under local anesthesia to minimize discomfort.

Photodynamic therapy (PDT), where a special cream is applied followed by light exposure to treat the patches.

Preventive Measures and Lifestyle Adjustments

To prevent the worsening of actinic keratosis and reduce the risk of skin cancer, consider the following actions:

Regularly inspect your skin for any new or changing patches.

Apply sunscreen with an SPF of at least 30 before sun exposure and reapply as needed.

Wear protective clothing and hats that shield your arms and legs when outdoors.

Avoid sunbathing and the use of tanning beds, as they can further damage the skin.

Steer clear of direct sunlight between 11 am and 3 pm, when the sun's rays are most intense.

Additional Considerations

For those who consistently protect their skin from the sun, consider supplementing with 10 micrograms of vitamin D daily to ensure adequate levels, as sunlight is a natural source of this essential vitamin. Maintaining a balance between sun protection and vitamin D intake is key to overall skin health.
