Keratosis patches are frequently found on areas of skin exposed to the sun. Common areas affected by solar keratosis include the

Face, Neck, Lips, Ears, Forearms, Scalp and the Back of hands

Although solar keratosis and actinic keratosis lesions are not usually serious – a small proportion of them can develop into skin cancer. We recommend booking a consultation with Dr Anna Hemming if you are concerned about a skin lesion or think you may have solar keratosis or actinic keratosis. Dr Hemming can diagnose and treat these lesions in a single appointment. Multiple lesions of Actinic Keratoses can be treated at the same time.

What is actinic keratosis (AK)?

Actinic keratoses, also known as solar keratoses, are areas of sun-damaged skin that typically develop after prolonged exposure to ultraviolet (UV) light. The term “actinic” or “solar” means caused by sunlight, while “keratosis” refers to thickened skin. These lesions often feel rough or scaly, like dry patches and are commonly pink but can also be skin-coloured or red. You may notice a change in skin texture before any visible discolouration. Common causes include sunbathing, use of sunbeds, outdoor work and living in sunny climates.

Where on the body do actinic keratoses typically appear?

Actinic keratoses most often develop on parts of the body that receive frequent sun exposure. These include the face, ears, scalp (particularly in balding individuals), lips, forearms and the backs of the hands. Because these areas are exposed to sunlight over long periods, they are more prone to developing these lesions.

How is actinic keratosis diagnosed at Thames Skin Clinic?

At Thames Skin Clinic, actinic keratosis is diagnosed through a thorough skin examination by Dr Anna Hemming, focusing on sun-exposed areas. She assesses for rough, scaly patches, which are typically pink, red or skin-toned and can confirm the diagnosis. In many cases, treatment can be offered during the same appointment, with multiple lesions treated together when needed.
