We read with interest the article of Thomas Emmanuel and colleagues recently published (1). We would like to elaborate and highlight some critical points whichmight alter the authors’ conclusions regarding their statement on long term effects of the treatment. In the light of currently given treatments for Psoriasis, DSC remains a valuable and attractive option for many reasons. Defined as a natural and selective balneo-phototherapy, DSC should benefit from the recommendations of many authors regarding the necessity to maintain Phototherapy “as an integral part of the dermatology treatment armamentarium” (2). DSC is an effective therapeutic option with almost no side effects, if realized under strict medical supervision, and proposed through a personalized UVB dosage regimen, adapted to the time of the sun exposure sessions (3, 4). Administered in this manner, this modality can be easily compared to artificial Phototherapy, in mean of cumulative UVB dose received, while controlling the potential long-term risks of UV treatment.
