Daylight-PDT
Make use of the advantages of the medically usable parts of visible light
The beginnings of photodynamic therapy date back to the year 1400 BC. In Egypt, psoralens derived from plants were used as photosensitizers activated by the power of the sun to treat skin diseases.
The same interaction of light and drug is now used in modern dermatology in the form of photodynamic therapy (PDT) to treat actinic keratosis, the most common type of precancerous skin condition.
