Everything you need to know

Actinic keratoses are small scaly patches of thickened or rough skin that usually develop in people over the age of 40 in response to years of sun exposure. Actinic keratoses are usually harmless but can be itchy and feel rough to the touch, their appearance can also cause embarrassment particularly when on the face. Actinic keratoses may turn into squamous cell carcinoma, a form of skin cancer, so it is important to get them checked and treated if required.

Alternative names: solar keratosis, sunspots, sun damage.

actinic keratoses causes

Actinic Keratoses are caused by sun damage from long periods of sun exposure, both natural and artificial. As they result from cumulative sun exposure over many years, they are more commonly found in older people. They are found predominantly on skin that experiences the most sun exposure such as the face, ears, hands and lower legs. Individuals who have fair skin and eyes and who burn easily are particularly at risk. They are not hereditary, however some of the risk factors such as fair skin do run in families.

What are the symptoms of Actinic Keratoses?

It can sometimes be hard to tell if you have actinic keratoses so it is worth checking with a consultant dermatologist if you are worried. Patches of actinic keratoses are usually rough to touch and range in colour from pink to brown. They can measure anywhere between 5mm and 30mm in width and can be thick and raised from the skin. They are often sore or itchy. If an area of your skin which resembles these characteristics starts to bleed, hurt or rapidly change in appearance or size, this may indicate that it is progressing toward squamous cell carcinoma, a form of skin cancer, and must be assessed by a consultant dermatologist as soon as possible.

Due to the risk of progression to skin cancer, it is generally advisable to treat actinic keratoses by removing it from the skin. This can be done through a range of techniques including creams, Photodynamic Therapy which uses a photosensitive cream and a light source, Cryotherapy which uses liquid nitrogen to freeze the lesion or Cutterage and Electrocautery which uses a small blade to remove the cells.

Frequently Asked Questions

Actinic Keratoses are not life-threatening themselves and small patches may disappear on their own but some actinic keratoses can turn into squamous cell skin cancer so can be considered as precancerous. If they are found and treated early, they do not have the chance to develop into skin cancer.

The patches can feel like sandpaper, they are dry rough and scaly. They usually range in size from 1cm to 2cm and can be itchy. They can either be the same colour as your skin, pink, red or brown.

As the patches of actinic keratosis are caused by exposure to the sun, they are most commonly found on areas of the body which are exposed to the sun such as the face, hands, arms, legs, ears and scalp.

If you have patches of actinic keratoses, it is important to get them checked by a dermatologist to reduce the risk of them developing in to skin cancer. To stop getting further patches and to look after your skin it is important to

  • use sun cream before exposing your skin to the sun
  • wear clothing which will protect your skin from the sun
  • do not use sunbeds or sunlamps
  • avoid the sun when it is at it’s strongest (between 11am and 3pm)

Actinic keratoses are usually little cause for concern. Small patches may disappear by themselves. However, it is important to adopt good sun-protection habits.

As actinic keratoses are caused by exposure to the sun, the key to prevention is avoiding the sun when its rays are most intense, especially around the middle of the day. Before going outdoors follow the usual sun safety measures of applying sunscreen with a high SPF and protection from both UVA and UVB light and wearing clothes designed to provide sun protection. It is also important to follow these steps if you already have signs of actinic keratoses in order to reduce the chances of them developing into skin cancer.
