Study type
Interventional
Description of intervention(s) / exposure
PDT-eze (a spray made up of naturally derived actives menthol/ginseng) topically administered 2-4 sprays to 1/2 face or 1/2 forearm (whether applied to face or forearm will be determined on clinical evaluation of severity of solar dermopathy in these areas, with clinician selecting most severe area for treatment) 10 minutes prior to onset of illumination and further 2-4 sprays at any time during the course of illumination that is requested by the subject – ensuring no cross contamination between each side of face or forearm. Illumination shall comprise 20minutes of blue light at 470nm followed by 10minutes of red light at 640nm using a TGA approved light source.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Trial patients will be enrolled in the trial as either a ‘face or forearm’ subject according to the clinical assessment of solar dermopathy made by the study clinician at each trial centre. 1/2 face (left or right) and left or right forearms will then be randomised to receive topical application with PDT-eze (case) or placebo (controls) at the study control centre utilizing a validated computer based randomisation tool.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence for randomisation was generated via an internet randomisation generator via the following website:
http://www.randomization.com/

Available using seeds 1303 for forearm; 7323 for face.
Masking / blinding
Blinded (masking used)
