The photodynamic therapy is a highly effcient, evidence-based and beneficial procedure to repair sun-damaged skin and actinic keratoses.

Pinke Laserstrahlen Auf Schwarzem Grund

Modern, efficient and gentle.

The latter lesions are an early form of skin cancer (early SCC) and need to be treated, as they can suddenly develop into an SCC. So, if you experience a reddish, scaly spot that does not vanish for weeks, particularly on sunlight exposed areas (forehead, scalp, nose, ears) it can be such a lesion. For the PDT a special cream (A-LA) is applied to the affected areas. This cream is left on the skin for three hours, and it marks the damaged cells. When the light therapy is applied, it specifically targets the damaged cells so the body is capable of removing them, leaving younger, healthier looking skin. The treatment has the added-value of a rejuvenating effect. This therapy is more specific than e.g. liquid nitrogen as it is more specific at identifying and attacking the damaged cells.


The Erbium-lag laser in FRAXEL (i.e. fractional) mode is used to enhance performance: laser assisted drug delivery and PDT: LADD-PDT.
