The digital medical device for solar photoprotection
Less skin erythema and improved vitamin D levels for Sun4Health® users
Sun4Health is a medical device smartphone app designed to enable a safe sun exposure, minimising the risks and maximising the benefits for the health.
It is especially suited for photosensitive skin, out-door workers, vitamin D deficiency at–risk people and Actinic Keratosis (AK) patients.
The app allows to plan outdoor activities and personalize photoprotection measures according to your skin features, tracking the solar radiation dose for preventing erythema (sunburn) and long-term photoinduced skin diseases.
The benefits of the App have been demonstrated in a clinical field study conducted in collaboration with King’s College London and MedCin Clinical Research Center involving more than 150 healthy volunteers in total demonstrated the benefits of using the Sun4Health® apps in real-world conditions1,2.
The results show that the Sun4Health® app is safe and induce to modify sun exposure behavior to reduce the level of skin erythema (28% less than control, 33% for eyewear 3D version), yet increasing the level of vitamin D synthesis (4 times higher than control, 14 times for eyewear 3D version).
According to more than 75% of the volunteers, the everyday use of the Sun4Health app positively modifies behaviour for a healthier lifestyle for sun protection and vitamin D intake.

How it works
Monitoring
Monitor your sun exposure time left for getting enough vitamin D with minimal sun damage risks (e.g. sunburn, AK development), updating your activity, scenario, clothes and sunscreen applied during the day
Planning
Plan your outdoor activities and body part-specific sun protection (e.g. SPF, sunscreen quantity) by simulating their impacts and getting personalised recommendations
Profiling
Assess your phototype and skin sensitivity to sunlight. If you are an AK at-risk patient, insert your personal sun damage risk factors (e.g. immunodeficiency)
Analytics
Review your sun exposure habits and get actionable insights, including the cumulative sun damage level minimised thanks to the app recommendations (e.g. optimal use of sunscreen, outdoor activity re-planning)
Additional Modules
To personalise and optimise your outdoor exposure benefits and minimise risks, you can purchase the following add-on app modules.
- Vitamin D add-on
To safely track and obtain a vitamin D level from sunbathing and form nutritional supplements when needed - Pollution add-on
To safely plan the best exposure time slot and urban path to minimise the impact of the atmospheric pollution on your skin and your health and monitoring it during your outdoor activities - Actinic Keratosis add-on
To support the prevention of new AK lesions for AK at-risk persons and AK chronic patients - 3D (Smart Glasses compatible)
To obtain body site specific recommendations and alerts for minimising skin
