Quantification of skin sensitivity to ultraviolet radiation using ultrawideband optoacoustic mesoscopy.

Dear Editor, Phototesting is used to assess individual sensitivity to ultraviolet (UV) radiation in order to determine adequate UV dosage for phototherapy.1 Under the standard procedure, small skin areas are exposed to increasing doses of UV radiation. Moreover, the results indicate that UWB-RSOM could be a useful tool to detect the suberythemal response of the skin to UV radiation, which may increase the sensitivity of phototesting.
