JenLab is the leading specialist in multiphoton tomography. Their innovative tomographs create scar-free and label-free optical biopsies and make it possible to detect skin cancer much earlier with subcellular resolution directly on the screen. The efficiency of anti-aging cremes can be evaluated and skin modifications of astronauts during long-term space flights investigated. Usually practitioners assess an abnormal part of a patient’s skin with their naked eye. In most cases, a biopsy will be carried out that causes pain and scars occur. The skin sample will be tested in a laboratory, a process that is not only costly but might also take weeks, leaving the patient with uncertainty.
