Also known as solar keratosis, actinic keratosis is the most common skin condition caused by sun damage on face. It’s a small, thickened, scaly growth on the skin on sun-exposed areas such as the head and face that is caused by excessive exposure to ultraviolet (UV) rays. They can be anywhere between 1-3 cm in size and can be light, dark, pink, red, the same colour as your skin, or a combination of all or some of these.
People with fair skin who do not tan easily are most commonly affected because they have less protective melanin. Sometimes they go away or fade away, or they may stay unchanged for years. It is important to keep an eye on it and see your GP if it grows larger or is something you’re worried about.
