What is actinic keratosis?
Actinic keratosis is a precancerous patch of sun-damaged skin. It often feels rough or sandpaper-like and commonly appears on the face, scalp, ears, forearms and hands. Most do not become cancer, but some can progress to squamous cell carcinoma, so diagnosis, treatment and sun protection are important.

Understanding actinic keratosis
Actinic keratosis is caused by long-term ultraviolet exposure. It develops when sun-damaged keratinocytes, the main cells in the outer skin layer, become abnormal and form rough scaly patches.
AKs are not invasive skin cancers, but they sit on a spectrum of sun damage and may progress in some cases. They are also a marker that the surrounding skin has received significant cumulative UV exposure.
What actinic keratosis looks and feels like
Texture
Many people feel AKs before they see them. They may feel like fine sandpaper or dry scale.
Colour
Lesions may be pink, red, tan, brown or skin-coloured with adherent scale or crust.
Behaviour
They may flake off and return, feel tender in sunlight or gradually become thicker.
Common locations
Forehead, temples, nose, ears, bald or shaved scalp, forearms, backs of hands and other sun-exposed areas.
Concerned about a rough sun-damaged patch?
A dermatologist-led assessment can confirm whether it is actinic keratosis and whether treatment, monitoring or biopsy is appropriate.
Diagnosis and when to seek assessment
Diagnosis is often made clinically by examining the lesion and surrounding skin. Dermoscopy can help distinguish actinic keratosis from eczema, psoriasis, seborrhoeic keratosis or superficial skin cancer.
Seek assessment if a rough patch persists beyond six weeks, becomes painful, bleeds, thickens quickly, ulcerates or looks different from your other lesions. If a lesion is unusually thick or suspicious, skin biopsy or diagnostic analysis may be recommended.
Actinic keratosis treatment options
Cryotherapy
Liquid nitrogen freezes abnormal cells. It is quick and often suitable for individual lesions.
Curettage, cautery or excision
Thicker or suspicious lesions may need removal under local anaesthetic, sometimes with histology.
Prescription field therapy
Medicated creams can treat visible and subclinical lesions across a sun-damaged area.
Photodynamic therapy
PDT uses a photosensitising cream and light activation to target atypical cells, often with good cosmetic outcomes on the face or scalp.
Laser resurfacing
Fractional or ablative laser resurfacing may be considered for selected sun-damaged skin to improve texture and support skin renewal.
Lesion-directed vs field-directed treatment
Lesion-directed treatments target individual visible patches. Field-directed treatments treat the wider sun-damaged area, including early changes that may not yet be visible.
Many patients benefit from a combination approach: clearing thicker or isolated lesions, then treating the broader field to reduce the chance of further lesions developing.
Aftercare and recovery
Healing
Redness, crusting or flaking may occur depending on the treatment used.
Gentle skincare
Cleanse gently, moisturise and avoid picking crusts or scales while healing.
Sun protection
Daily broad-spectrum SPF is essential during healing and long-term prevention.
Long-term skin health and prevention
Daily broad-spectrum SPF 30–50 is one of the most important steps to reduce new actinic keratoses and support lower skin cancer risk. Hats, UV-protective clothing, shade and avoiding sunbeds are also important.
Periodic skin checks are recommended for patients with multiple AKs, previous skin cancer, significant sun damage or immunosuppression.
