Introduction
Actinic keratoses, also known as solar keratoses, are common precancerous skin lesions caused by years of sun exposure. At our dermatologist clinic, we specialise in early detection and treatment to halt progression to squamous cell carcinoma while prioritising minimal discomfort and excellent cosmetic results. This guide explores diagnosis, proven treatment options, and practical prevention steps for patients in London and Hertfordshire.
As the video suggests, regularly checking your skin, or joining one of our screening programs will help bring about key early intervention.
What Are Actinic Keratoses and Why Treat Them?
Actinic keratoses appear as rough, scaly patches, often red, pink, brown, or skin-coloured, typically on sun-exposed areas such as the face, scalp, ears, forearms, and hands.
These lesions signal chronic UV damage and carry a small but real risk of transforming into squamous cell carcinoma over time, especially with multiple lesions or in high-risk individuals like the immunosuppressed.
Early treatment not only clears existing lesions but also reduces future skin cancer risk, making it essential for long-term skin health.
How a Dermatologist Diagnoses Actinic Keratoses
Diagnosis usually relies on clinical appearance, enhanced by dermoscopy for detailed lesion assessment.
In unclear cases, a small biopsy may confirm the grade (mild, moderate, or severe) and rule out invasive cancer.
Effective Treatment Options for Actinic Keratoses
Treatment choice depends on lesion number, thickness, location, and patient factors. We offer a range of evidence-based approaches.
Topical Treatments for Field Cancerisation
For widespread or multiple lesions, topical therapies target both visible and subclinical damage.
- 5-fluorouracil (5-FU) cream: Highly effective for field treatment, often applied for weeks with strong clearance rates.
- Imiquimod cream: Immune-modulating option, suitable for the face and scalp.
- Diclofenac gel: Milder for thinner lesions.
- Tirbanibulin ointment: A newer, convenient option with shorter application time and good tolerability.
These creams often cause temporary inflammation but deliver excellent long-term results.
Cryotherapy (Freezing)
Liquid nitrogen freezes individual, thicker lesions quickly and effectively, with minimal scarring in most cases.
Ideal for isolated actinic keratoses, this in-clinic procedure suits busy patients.
Photodynamic Therapy (PDT)
A light-activated treatment using a photosensitising cream followed by light exposure to destroy abnormal cells.
Our clinic offers both conventional and daylight PDT in a comfortable setting, providing high clearance with good cosmetic outcomes, especially for facial areas.
Other Advanced Options
- Chemical peels: Refresh sun-damaged skin while treating superficial lesions.
- Laser therapy: Precise removal for sensitive or resistant areas.
We select treatments to balance efficacy, comfort, and aesthetics.
Prevention and Long-Term Skin Care After Treatment
Sun protection remains vital to prevent new lesions.
- Apply broad-spectrum SPF 50 daily, even on cloudy days.
- Wear protective clothing, hats, and seek shade during peak hours.
- Perform regular self-exams and attend annual checks with a dermatologist.
Post-treatment moisturisers and emollients support healing and maintain skin barrier health.
Conclusion
Actinic keratoses are highly treatable when addressed early by an experienced dermatologist, offering excellent clearance rates and reduced skin cancer risk.

Frequently Asked Questions
These answers address common concerns about actinic keratoses treatment to help you make informed decisions.
It is precancerous, with a low individual risk of progressing to squamous cell carcinoma, but multiple lesions increase this risk over time; early treatment prevents complications.
Some may resolve temporarily, but they often recur without treatment, and sun protection alone is insufficient for established lesions.
Topical creams may cause inflammation and discomfort during application, cryotherapy feels cold and stingy, while PDT involves mild burning; we provide guidance to minimise issues.
Topicals span weeks, cryotherapy is quick in-clinic, and PDT sessions last about an hour with follow-up as needed.
Yes, as they stem from cumulative sun damage, ongoing prevention and monitoring reduce recurrence.
For new or changing scaly patches, especially on sun-exposed skin, or if over-the-counter measures fail, prompt specialist review ensures accurate diagnosis and optimal outcomes.
