Objective; to choose the optical clearing agent with the best illuminating ability in the long-wave UV spectrum used in phototherapy. Material and methods. Ex vivo skin samples were used as objects of study. Measurement of the total transmission spectra of the skin sections was carried out on a multi-channel spectrometer Ocean Optics QE 65000 (Ocean Optics, USA) using 4 optical clearing agents (40% glucose solution, glycerol, propylene glycol, oleic acid).
Results. Having conducted a comparative analysis of ex vivo data collected from spectroscopy of these optical clearing agents at a wavelength of 370 nm, it was found that the maximum optical clearing was achieved using propylene glycol at 44 minutes, which was 11.56%. Conclusion. The use of optical clearing agents is possible not only to improve the visualization of the skin structure, but also to explore the dynamics of light transmission in long-wave UV A-1 therapy of patients.
