Keratosis senile or age-related pigmentation (in Latin “keratosis senilis”) is a disease in which the detachment of the stratum corneum of the skin is impaired.

This process usually occurs faster on the following parts of the body: face, neck, hands, knees, elbows and legs. Typically, symptoms and signs of keratoses become noticeable after the age of 60, but the onset of development can occur in younger people. The likelihood of occurrence increases if there is a genetic predisposition. There is also a connection between the disease and the use of solar and halogen lamps during exposure to the sun. In this case, photosenile keratosis develops, when the layer of keratinized cells is very thin and hyperpigmented. Such skin is at increased risk of developing malignant tumors. It must be taken into account that treatment should be aimed at the underlying cause of the pathology. This
