Abstract
Objective To evaluate the quantitative evaluation of red and blue light to acne patients.Methods The 150 acne patients were enrolled randomly in study during Jun 2010 to Jun 2011 in our laser center.They were using red and blue light two times in one week for four weeks.Before treatment,after four times and eight times were evaluated and analyzed using VISIATM complexion analysis system and SOFT 5.5 skin property system.Results VISIA data showed that pigment spot,texture and pore were not different before and after using red and blue light(P0.05).The porphyrin was improved after four times and eight times compare before(P0.05).There were not different between after four times and after eight times(P0.05).SOFT data showed that moisture and elasticity were not different before and after using red and blue light(P0.05).The only greases after four times treatment were improved compare before(P0.05).The pH and greases after eight times treatment were improved compare before(P0.05).There were not different between after four times and after eight times(P0.05).Conclusion Red and blue light could obviously reduce skin greases and change pH temporarily but could not change skin pigment and moisture in a certain degree.
