Actinic keratosis: symptoms
In the early stages it is not easy for laymen to recognize an actinic keratosis: At one or more places it comes first to one sharply reddenedthat look like fine sandpaper feels. Later, the horny layer thickens and it forms thick, partly yellowish-brown horn deposits, Their diameter can be a few millimeters to a few centimeters.

Actinic Keratosis: Cause & Diagnosis
Actinic keratoses develop on skin areas that are too strong UV radiation (especially sunlight) were exposed. The skin changes often become visible only decades after the intensive exposure to sunlight: the UV light damages the skin cells and their genetic material. This results in altered cells (atypical cells), which multiply strongly in the upper skin layer - the horny layer thickens. This process is very slow over several years. Eventually, the cells can degenerate into a spinalioma.
