Actinic keratosis (AK), also known as solar keratosis, is a common skin condition resulting from prolonged exposure to ultraviolet (UV) rays. This condition is characterized by rough, scaly patches on the skin, primarily affecting areas frequently exposed to the sun such as the face, ears, neck, scalp, chest, backs of hands, forearms, and lips. With the intense sun exposure in Dubai, effective management of AK is crucial to prevent its potential progression to squamous cell carcinoma, a type of skin cancer. Here, we explore effective strategies for managing actinic keratosis in Dubai, taking into account the unique environmental factors and healthcare resources available in the region.

1. Sun Protection and Preventive Measures:

a. Use of Sunscreen:

Consistent application of broad-spectrum sunscreen with a high SPF (30 or above) is essential. Given Dubai's year-round sunny climate, incorporating sunscreen into daily routines can significantly reduce UV damage. Reapplication every two hours, especially after swimming or sweating, is recommended.

b. Protective Clothing:

Wearing sun-protective clothing, such as long sleeves, wide-brimmed hats, and UV-blocking sunglasses, provides a physical barrier against harmful rays. Light-colored, tightly woven fabrics are particularly effective.

c. Avoiding Peak Sun Hours:

Limiting outdoor activities during peak sun hours, typically between 10 AM and 4 PM, can reduce UV exposure. Seeking shade whenever possible is also beneficial.

2. Topical Treatments:

a. Prescription Creams and Gels:

Dermatologists in Dubai may prescribe topical treatments such as 5-fluorouracil (5-FU), imiquimod, or ingenol mebutate. These medications work by selectively destroying abnormal skin cells.

b. Retinoids:

Topical retinoids, like tretinoin, can be used to treat and prevent AKs by promoting cell turnover and repair of sun-damaged skin.

c. Diclofenac Gel:

This nonsteroidal anti-inflammatory drug (NSAID) in gel form can help reduce the growth of actinic keratosis lesions by targeting the inflammation associated with UV damage.

3. Procedural Interventions:

a. Cryotherapy:

Cryotherapy involves the application of liquid nitrogen to freeze and destroy AK lesions. It is a quick, effective procedure commonly available in dermatology clinics across Dubai.

b. Photodynamic Therapy (PDT):

PDT combines a photosensitizing agent with a specific wavelength of light to target and eliminate abnormal cells. This therapy is particularly useful for treating larger areas with multiple lesions.

c. Laser Therapy:

Laser treatments, such as fractional laser or ablative laser therapy, can precisely target and remove damaged skin layers, promoting the regeneration of healthy skin.

d. Curettage and Electrosurgery:

This method involves scraping off the AK lesion followed by cauterization to minimize bleeding and reduce the risk of recurrence.

4. Regular Dermatological Check-Ups:

a. Skin Cancer Screening:

Regular check-ups with a dermatologist are crucial for early detection and management of AKs. Annual skin exams can help monitor any changes and ensure timely intervention.

b. Dermoscopy:

Dermoscopy, a non-invasive diagnostic tool, allows dermatologists to examine skin lesions with greater detail, improving the accuracy of AK diagnosis and differentiation from other skin conditions.

5. Patient Education and Lifestyle Modifications:

a. Awareness Campaigns:

Educational initiatives aimed at raising awareness about the risks of UV exposure and the importance of skin protection can empower residents to take proactive measures against AK.

b. Healthy Lifestyle Choices:

Adopting a healthy lifestyle, including a balanced diet rich in antioxidants and regular exercise, can bolster the skin’s resilience against UV damage. Hydration is also vital in Dubai’s arid climate to maintain skin health.

Conclusion:

Managing actinic keratosis effectively in Dubai involves a multifaceted approach that includes preventive measures, topical treatments, procedural interventions, regular dermatological check-ups, and patient education. By integrating these strategies into daily routines and healthcare practices, residents can significantly reduce their risk of developing actinic keratosis and its potential progression to skin cancer. Given the high levels of sun exposure in Dubai, prioritizing skin health and sun protection is essential for maintaining overall well-being.
