Combined Effect of Ultrasound-SLS on Skin Optical Clearing
Our previous studies demonstrated the ultrasound-induced skin optical clearing enhancement with topical application of optical clearing agents on in vitro porcine skin and in vivo human skin. The objective of this study was to develop more effective methods by simultaneously using two kinds of skin permeation enhancers. The effect of ultrasound (SP) in combination with a chemical enhancer, sodium lauryl sulfate (SLS), on skin optical clearing was investigated. Light transmittance and imaging depth of in vitro porcine skin were measured with spectroscopy and optical coherence tomography (OCT). Three treatments were performed: 1) 60% glycerol (60% Gly); 2) 60% glycerol $+ $15-min ...
