Home daylight-PDT treatment for Actinic Keratosis

Easily treat Actinic Keratosis using natural sunlight from the comfort of your patients' own home.

SmartPDT® enables the use of daylight-PDT, the natural alternative method to conventional laser or lamp photodynamic therapy, in a safe and reliable way remotely within the patient’s own home.

With its simple and effective smartphone-based application and web-portal dashboard interfaces, SmartPDT® has been designed for those who are both novice and well-trained in daylight-PDT. It provides doctors and healthcare staff with time-saving administrative solutions, actionable data, and accurate tracking of photosensitiser [Protoporphyrin IX (PpIX)] while offering optimal comfort and convenience for patients.

SmartPDT® is a CE marked software system, compliant to the European Medical Device Regulation 2017/745.

Explore The Main Features

Remote patient monitoring

SmartPDT® enables dermatologists and clinicians to monitor their patients' progress remotely, proactively adjust actinic keratosis treatment plans, supervise the patient behaviour during and after the therapy session and stay connected between visits.


Easy daylight-PDT scheduling

SmartPDT® makes treatment scheduling for each patient easy by highlighting the most suitable treatment time slot according to the weather forecast and clinical staff and patient availability.

Measured impact

Enhance care diagnostics using actionable, data-driven, and agile results personalised to the patient. Administrators and clinical staff can use SmartPDT® dashboards and reports for high-level healthcare intelligence and management use. Standard reports available include protocol adherence, precipitation, and UV exposure changes, PpIX dose, percentage of Minimum Erythemal Dose (MED) received, and patient feedback.

Instant and post-treatment feedback

Patients can take photos of their skin lesions through the app for their clinical staff to see and analyse without the need to go into the treatment centre. Remote patient monitoring of clinical markers like sun exposure, pain and skin lesions progression leads to improved outcomes and therapy adherence.

Patient support

SmartPDT® gently guides patients on when and how to prepare their treatment session. Using notifications and alerts to when the patient needs to start and finish their treatment, SmartPDT® ensures that both treatment and aftercare protocol procedures are followed.

Personalised sunlight protection

SmartPDT® uses HappySun® technology - siHeath’s innovative sensor-less personal solar radiation dosimeter - to continually measure the safe UV solar dose related to the patient’s phototype and what sunscreen factor they applied, and the PPIX effective radiation dose, in order to assure an erythema-free, safe and effective therapy session.

Scientifically approved

SmartPDT® uses satellite imagery and computer algorithms to determine in real-time the exposure to PpIX-effective visible and ultraviolet solar radiation, ensuring accurate and precise readings. The methodology for monitoring ground-level solar exposure by using satellite imagery has been scientifically validated thanks to the collaboration with the University of Dundee and Public Health England.

Our published research shows that the agreement between satellite-determined, weather-forecasted and ground-measured radiant exposure was better than any existing method or system published in literature for dPDT. Scientific validation of the real-time and forecasted radiant exposure algorithms was performed against direct ground-based measurements under all weather conditions in the UK (see the “Scientific Publications” section).
