Inclusion Criteria:

  1. Subjects with at least 12 distinctive and clinically confirmed mild to severe AK lesions (according to Olsen et al. 1991 (37)) with a diameter of ≥ 4 mm each, on either the face/scalp (including forehead, excluding eyes, nostrils, ears, and mouth) or the neck/trunk/extremities, within treatment field(s) of about 60 cm² in total.

  10. Any therapy such as cryotherapy, laser therapy, electrodessication, surgical removal of lesions, curettage, or treatment with chemical peels such as trichloroacetic acid within the treatment field(s), or within a radius less than 5 cm away from the treatment field(s) 4 weeks prior to screening.
  11. Any topical medical treatment of the skin within the designated time period below:

  15. Positive test for HIV antibodies, Hepatitis B-virus surface antigen (HBsAg) or positive Anti-hepatitis C-virus antibody (Anti-HCV) test.

  17. Breast-feeding women.
  18. Subject unlikely to comply with the protocol, e.g. inability to return for visits, unlikely to complete the study, or inappropriate in the opinion of the investigator.
  19. Prior participation in the study (participation is defined as having been screened).
  20. A member of study site staff or sponsor staff directly involved in the conduct of the protocol or a close relative thereof.
  21. Simultaneous participation in a further clinical study.

Reassessment of subjects is allowed once if sunburn, wounds, irritations, bleeding or skin infections detected at Visit 1 are expected to resolve within the screening period.

Reassessment can be done on the day of the actual treatment.

Dosing day exclusion criteria:

  1. Febrile or infectious illness within 7 days prior to Visit 2.
  2. Subjects with sunburn, wounds, irritations, bleeding or other confounding skin conditions within illumination areas at Visit 2.
  3. Use of topical NSAIDs inside and outside the treatment field(s) or systemic intake of NSAIDs within 7 days prior to Visit 2.

In case a subject meets one of the dosing day exclusion criteria, Visit 2 can be rescheduled once within 14 days. Meeting any of the dosing day exclusion criteria on the rescheduled visit will lead to discontinuation of the trial.
