Continuous activation of PpIX by daylight is as effective as and less painful than conventional photodynamic therapy for actinic keratoses; a randomized, controlled, single-blinded study
S.R. Wiegell,Merete Haedersdal,Peter A. Philipsen,P. Eriksen,Claes D. Enk,Hans Christian Wulf +5 more
TL;DR: Daylight‐PDT would make the treatment independent of the clinic and less painful due to the continuous activation of small amounts of porphyrins during its formation.

Vitamin D production after UVB exposure depends on baseline vitamin D and total cholesterol but not on skin pigmentation.
Morten Karsten Bentzen Bogh,Anne Schmedes,Peter A. Philipsen,Elisabeth Thieden,Hans Christian Wulf +4 more
TL;DR: The increase in 25(OH)D level after UVB exposure was negatively correlated with baseline 25( OH)Dlevel and positively correlated with Baseline total cholesterol level, but no significant correlations were found with constitutive or facultative skin pigmentation.

UV radiation exposure related to age, sex, occupation, and sun behavior based on time-stamped personal dosimeter readings.
TL;DR: High UVR doses are connected with risk behavior, except for outdoor workers, and there is no need to change sun exposure habits on days without risk behavior.

Daylight‐mediated photodynamic therapy of moderate to thick actinic keratoses of the face and scalp: a randomized multicentre study
S.R. Wiegell,Susanne Fabricius,Monika Gniadecka,Ida Marie Stender,Berit Berne,S. Kroon,B. L. Andersen,Cato Mork,Carin Sandberg,Kristina S Ibler,Gregor B.E. Jemec,K. M. Brocks,Peter A. Philipsen,Jakob Heydenreich,Merete Haedersdal,Hans Christian Wulf +15 more
TL;DR: Lightning‐mediated PDT is a simple and tolerable treatment procedure for PDT and Methyl aminolaevulinate‐PDT is approved for the treatment of thin or nonhyperkeratotic AKs on the face and scalp.

How Finsen's light cured lupus vulgaris.
Kirsten Møller,Brian Kongshoj,Peter A. Philipsen,Vibeke Østergaard Thomsen,Hans Christian Wulf +4 more
TL;DR: Production of singlet oxygen through radiation of porphyrins with light of e.g. 400 nm seems to be a most plausible explanation why Finsen's therapy worked in spite of the lack of shortwave ultraviolet radiation, whichFinsen believed was the most effective radiation for treating skin tuberculosis.
