Actinic keratosis

Actinic keratosis describes a skin condition of sun damaged skin, usually located on nose/face, scalp, chest or back of the hand. It can be a precursor of skin cancer and therefore should be treated in an early stage.


Local treatment with cremes such as 5 fluorouracil or photodynamic therapy destroy actinic keratosis. New skin cells will be formed and the affected spots heal with a new skin layer


Aktinische Keratose can be treated by PDT. The affected skin is covered with a cream. The cream is then absorbed by the skin cells and makes it sensitive to certain wavelengths of light. The cream takes 3 hours to be properly absorbed by the skin cells. Then the skin is illuminated with a special lamp. The following days, a superficial abrasion often develops and heals the skin without scarring.
